Travelling around the Schengen Area

Europe is a continent that is relatively small but with many independent countries. Under normal circumstances, travelling through multiple countries would mean having to go through visa applications and passport control multiple times. The Schengen zone, however, works somewhat like one country in this respect. As long as you stay in this zone, you can generally cross borders without going through passport control checkpoints again. Similarly, by having a Schengen visa, you do not need to apply for visas to each of the Schengen member countries separately, hence saving time, money and paperwork.

While most EU countries are also Schengen members, the two are not the same, and even some territories of EU countries are outside the Schengen area.

The Schengen Area is not the same as the European Union (EU). Not all EU countries are part of the Schengen zone and not all Schengen countries are part of the EU. As such, when you as a non-EU citizen go to an EU member state that does not participate in the Schengen agreement, you will be subject to their completely separate visa, entry requirements and passport control systems. The most notable example of an EU non-Schengen member is Ireland. Cyprus is not yet part of the Schengen zone but are expected to join in the future. Iceland, Norway, Switzerland and Liechtenstein are part of the Schengen Area but not members of the EU. There is provision for Gibraltar to join the Schengen Area, but this hasn't been implemented yet. For EU citizens, the Schengen Zone is of somewhat less importance, as there is the related but separate concept of free movement inside the EU.

The Schengen Zone only covers immigration controls, whilst the EU is effectively a customs union. Therefore, you do not need to pass through customs when travelling between a Schengen and a non-Schengen EU country, but you will need to pass through immigration controls (e.g., Ireland to Germany or vice versa). The converse is true for travel between EU and non-EU Schengen countries: you must pass through customs, at least if you have goods to declare, but not immigration (e.g., Switzerland to France or vice versa).

The countries that form the Schengen Zone are Austria, Belgium, Bulgaria, Croatia, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and Switzerland.

Romania and Bulgaria are EU member states and joined the Schengen Area on March 31, 2024, but while air and sea border controls have been lifted (regarding commercial craft), passport checks are still present on land borders and when travelling by private yacht.
Cyprus is seeking to join the Schengen zone by the end of 2024.
The microstates Monaco, San Marino and Vatican City are not part of the Schengen Area and have differing formal relationships with it, but they all have open borders with neighbouring Schengen countries and can be legally entered with a Schengen visa.
Andorra is not part of the Schengen Area and conducts routine customs inspections at its border crossings with Spain and France. Passports are generally only given a cursory check but not stamped, and tourists may legally visit with a Schengen visa. Although a single-entry Schengen visa will technically be invalidated by visiting Andorra, in practice this is not enforced by immigration.

A Schengen visa and visa-free travel to the Schengen area (for eligible non-EEA and non-Swiss nationals) are valid for only short stays (those that are 90 days or less within a 180-day period – for all the area). Any non-EEA or Swiss national who wishes to stay for a longer period must apply for an appropriate long stay national visa, which is valid for a particular country only. Moreover, a Schengen visa might not be valid to visit overseas territories of a particular Schengen country (e.g., French overseas territories or Greenland). This article focuses on short stay tourist, family visit, and business visit visas as well as visits to the Schengen zone for those purposes. Travel for other purposes will require a national visa specific to the Schengen country that purpose will be undertaken in.

Visa and non-visa nationals

Citizens of the European Economic Area (EU, Iceland, Norway and Liechtenstein), and Switzerland only need a valid national identity card or passport, they do not need a visa for the Schengen Area and are generally allowed to stay for as long as they want.

The nationals of the following other countries do not need a visa for entry into the Schengen Area: Albania⁽¹⁾, Andorra, Antigua and Barbuda, Argentina, Australia, Bahamas, Barbados, Bosnia and Herzegovina⁽¹⁾, Brazil, Brunei, Canada, Chile, Colombia, Costa Rica, Dominica, El Salvador, Grenada, Guatemala, Honduras, Israel, Japan, Malaysia, Mauritius, Mexico, Moldova⁽¹⁾, Monaco, Montenegro⁽¹⁾, New Zealand, Nicaragua, North Macedonia⁽¹⁾, Palau, Panama, Paraguay, Peru, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Samoa, San Marino, Serbia^(1, 2), Seychelles, Singapore, South Korea, Taiwan⁽³⁾ (Republic of China), Timor-Leste, Tonga, Trinidad and Tobago, Ukraine⁽¹⁾, United Arab Emirates, United Kingdom, United States, Uruguay, Vanuatu, Vatican City and Venezuela. The same applies to persons holding Hong Kong SAR or Macau SAR passports and all British nationals.

The non-EU/EFTA visa-free visitors noted above may not stay more than 90 days in any 180 day period in the Schengen Area as a whole and, in general, may not work during their stay (although some Schengen countries do allow certain nationalities to work – see below). The counting begins once you enter any country in the Schengen Area and is not reset by leaving the Schengen are. Exceptions may apply for New Zealand citizens and certain other nationalities in certain countries.
Starting in mid-2025, non-EU/EFTA visa-free visitors are also required to apply for a clearance through the European Travel Information and Authorisation System (ETIAS) at least four days prior to their trip (those without ETIAS will not be permitted to board their flights). Similar to the ESTA scheme for the US, the traveller will have to answer a series of questions to assess if they are a security risk to the Schengen area. The fee is €7 for travellers aged 18 to 70, free for children and the elderly. Once ETIAS clearance is approved, it is valid for up to three years. If the traveller's passport expires earlier than that, a new clearance is required for the new passport.

If you are a non-EU/EFTA national (even if you are visa-exempt, unless you are Andorran, Monégasque or San Marinese), make sure that your passport is stamped both when you enter and leave the Schengen Area. Given that passports are not always scanned into the computer databases upon entry and exit, without an entry or exit stamp, you may be treated as an overstayer when you try to leave the Schengen Area. Thus, you may be refused entry or face intense questioning the next time you seek to enter the Schengen Area as you may be deemed to have overstayed on your previous visit. If you cannot obtain a passport stamp or the dates indicated there are illegible, make sure that you retain documents such as boarding passes, transport tickets, passport stamps from the next country, currency exchange receipts, credit card charge slips, etc. which may help to convince border inspection staff that you have stayed in the Schengen Area legally.

If your status depends on the United Kingdom's former membership of the EU, Brexit has probably affected your rights.

Non-EEA nationals who would need a Schengen visa, but have an existing residence permit or long-stay national visa for one of the Schengen countries, generally do not need to apply for another Schengen visa to visit the other Schengen countries while that permit or visa is valid. However, their visit in the other Schengen area countries will still be limited to the standard 90-day per 180-day period. Work or residence rights are also generally not extended outside the country that issued this long-stay visa.

In some cases, certain nationals who do not require a Schengen visa may be able to legally work in a few individual Schengen countries for the duration of their 90-day visa-free period. However, these work rights do not necessarily extend to other Schengen countries. Check the Wikivoyage pages of the individual Schengen countries and the websites of those countries' immigration departments to find out if and for which countries your nationality may qualify for such arrangements.

Transiting

Citizens of 12 countries need a transit visa even for airside transits: Afghanistan, Bangladesh, Democratic Republic of the Congo, Eritrea, Ethiopia, Ghana, Iran, Iraq, Nigeria, Pakistan, Somalia and Sri Lanka. And citizens of a number of other countries need a transit visa even for airside transits in some Schengen countries: Algeria, Angola, Armenia, Cameroon, Central African Republic, Chad, Republic of the Congo, Côte d'Ivoire, Cuba, Djibouti, Dominican Republic, Egypt, The Gambia, Guinea, Guinea-Bissau, Haiti, India, Jordan, Lebanon, Liberia, Libya, Mali, Mauritania, Nepal, Niger, Palestine, Philippines, Russia, Senegal, Sierra Leone, South Sudan, Sudan, Syria, Togo, Turkey, and Yemen.

Everyone else is allowed to change planes at an airport in the Schengen area without obtaining a visa. However, if the airport you are transferring to is in the Schengen area as well or you intend to leave the "airside" area of the transit airport, this means you're entering the Schengen area and the normal rules governing Schengen visas and entry for visitors apply. This also applies if you have a flight within the Schengen area as part of an itinerary beginning and ending outside it: For instance, a Moroccan citizen travelling from Rabat to New York with stops in Paris and Amsterdam would need a Schengen visa because the Paris-Amsterdam flight cannot be accessed without entering the Schengen area.

Requirements for a visa

In general, if your nationality needs a Schengen visa for either business, tourism or family visits, you usually will need to procure the following documents (specific requirements vary slightly per embassy and jurisdiction so check with the embassy where you're applying at for the specific and additional requirements):

Basic requirements
- Completed application form (the form can be downloaded from the website of the embassy concerned or filled out and submitted electronically and later printed) and some member states may also request you to fill-out an additional form. Parents will need to sign the application form of minors whether they will accompany them or not.
- Passport with at least two blank pages, which must be valid for at least three months from the day you return
- passport-sized ID photograph (please check the website of the embassy you are applying to determine how the photo should look like)
- copies of previous Schengen visas (if previously issued)
- Application fee
  - €80 for most applicants
  - €35 for children at least 6 years old but younger than 12 years old and nationals of Albania, Bosnia-Herzegovina, Montenegro, North Macedonia, Serbia, Russia, Ukraine and Moldova
  - free for children 5 years old and below, spouses and minor children of EU nationals as well as pupils/students accompanied by teachers on a school trip
  - The fees must usually be paid in the local currency equivalent (the exact/actual amount as well as acceptable modes of payment will be specified by the embassy/consulate concerned).
  - If the embassy/consulate outsources the administrative aspects of the application to a third party (e.g., to VFS), then a fee may be charged by these third parties in addition to the above fees.
- For those applying in a country where they are not a citizen of but have legal residence: Residence permit which must be valid for at least three months from the day you return.
- Minors who are travelling alone (or with an adult who is not a family member) and in some cases with only one parent may need to secure a permit to travel form or its local equivalent from local authorities in their home or resident country signed by the parents or legal guardian who is not accompanying the minor. This requirement depends on the local laws.
Proof of socio-economic ties and finances
- Employment certificate/letter and recent payslips (if employed), or enrolment certificate/letter from institution (if a student). These may be known as "letters of no contest". As much as possible, they should state the period in which you are allowed to go on a holiday or business trip. In some cases, if you are unemployed or a dependant on someone else financially, you will have to procure an affidavit of support and/or a declaration form.
- Bank statements covering the last 3 months prior to the application. The specific amount required to be in the balance depends on the member state whose embassy you are applying at (typically €40-60 per day per applicant on your party plus enough to cover unpaid ticket costs, accommodations, pre-booked tours). If you do not have a bank account, traveller’s cheques might be accepted by some embassies. If you reside outside your country of your citizenship (e.g. a Thai citizen living in the UK) and you have bank accounts in both countries, the embassy may only honour bank account documents issued in the country you are residing in.
- If available or applicable, any other evidence that shows your strong motivation to return to your country of citizenship or legal residence at the end of your trip, e.g. property titles, tax returns, share certificates, certificates showing immediate family in your home country. If you reside outside your country of your citizenship (e.g., a Thai citizen living in the UK) and you own property in both countries, the embassy may only honour property titles, assets, etc issued in the country you are residing in.
Travel plan and Proof of travel arrangements
- Detailed travel itinerary
- Confirmed transport arrangements .
- Confirmation of accommodation arrangements. These have to establish that the country whose embassy you're applying at is your main destination (see next section).
  - For tourists staying at a hotel/hostel, your confirmed bookings.
  - If you intend to stay with friends/relatives, they may need to course their invitation through local authorities, fill-in official paperwork and post it to you.
- Official letter/invitation from organisers/sponsors, if you are on a business trip or conference.
- Travel insurance that covers at least the entire Schengen Zone for the duration of your trip and at least €30,000 in emergency treatment and medical repatriation.
Additional requirements for spouses and children of EU nationals only
- copy of passport of the EU national
- marriage certificate (for spouses)
- birth certificate with the name of the EU national parent (for children)
- other proofs of relationship as may be requested by the consulate

Do not submit original copies of the above-mentioned documents to the application centre as they may not be returned to you (except the passport of course).

The application form may have an option of whether you want a single or multiple entry visa. However, the latter is rarely granted for first-time visitors and not all countries grant it at all unless you can demonstrate that in between two Schengen states, you intend to visit a non-Schengen country.

Visa Requirements

Setting an appointment

Visas cannot be applied for at the border, nor at a "visa hub": you need to apply early enough, from your home country (or abroad, if there is no consular services in your country), with few exceptions. In most cases, you need to show up in person, even if travel to the consulate is awkward.

In applying for a Schengen visa, there is no such thing as applying at the embassy, consulate or visa application centre of your choice. The one at which you must apply will depend on where you plan to actually go, how long you plan to spend in each of the countries, what the main purpose of your trip is and your country of residence.

If you only intend to visit one country, then you must go to the designated application centre for that particular country. Don't visit the visa application centre for Spain if you will only visit Austria; go to the visa application centre servicing Austria. If the country you wish to visit has no embassy or visa centre in your home country, it is possible that the country has outsourced applications to a Schengen country represented in your home country, but this has to be checked.
If you intend to visit more than one country, then you must identify the country which is your main destination. A main destination is defined as the destination where you will spend the longest time in if the purpose of your trip is the same for each of the countries you will visit, or where the main purpose of your trip will take place if you have more than one purpose. Your main purpose will also depend on the visa you are ultimately applying for.
- For example, if your itinerary says you will spend 2 days in Germany, 4 days in Sweden, 3 days in Poland and 1 day in Belgium all for a holiday, you need to apply for a visa at the Swedish application centre.
- If you will spend 5 days in France for a holiday but you will do this after attending a 3-day conference in Italy, you must go to the Italian application centre.
If there is no clear main destination and the purpose of your trip is the same everywhere, that is, you will spend almost exactly the same amount of time in each member state then you should lodge your application at the application centre of the member state where you intend to first arrive at. For example you will enter through France and spend 3 days there, then 3 days each in Denmark and finally Switzerland all for a holiday; you must go to the French application centre for the visa.

You can only apply at the application centre that has jurisdiction over the country (and possibly city) where you live. You will need to present proof of residence, at least if that country isn't the one you are a citizen of. If you are a temporary visitor in a third country, only in special circumstances can you apply for the visa there; travelling home for the application being impractical seldom counts.

Check the relevant embassy's website for more details on how to set an appointment, where you need to go, and what else you need to bring. If a member state has no mission in your home country, the embassy you need to visit may be in another country, serving also your area. In some cases, visa processing may be delegated to another Schengen country, accepting and possibly processing applications on behalf of the Schengen country to which you intend to lodge your application. This sometimes applies even if the Schengen country in question has an embassy in your home country. For instance, the Danish embassy in Singapore processes visa applications for Norway, Finland and Iceland even though the former two operate their own embassies in Singapore.

Get all your paperwork in order as early as possible, especially if it takes days to process or needs to be posted to you. Personal appearance is generally required and is usually by appointment only; walk-ins are only allowed in a few cases. Appointment slots run out quickly so book an appointment early. The application may be filed up to six months in advance of your scheduled journey.

Make copies of all relevant documents for later use. Give away the originals only when you need to.

Attending the appointment

In general, personal appearance at the application centre is required; that is, an agent cannot lodge the application on your behalf. Make sure you be at the application centre at least 15 minutes before your appointment and that your documents are in order.

The staff at the window will inspect your documents, ask routine questions about your trip, collect the application fee, and normally take biometric fingerprints and digital photographs. If your documents are insufficient or out of order, or you are requested to submit more, then you will usually need to make a new appointment. Your application will not be processed until this is satisfied.

Processing time depends on a variety of factors. They include the applicant's nationality (some nationalities are subject to consultation with other member states), purpose of visit, time of the year, outstanding documentation, referral of application to different government departments, and staffing levels at the embassy. Before the appointment is over, the application centre will advise you on when and how you can claim your passport (either by returning personally or by post).

After applying

If you receive a Schengen visa, make sure you check to see the information is correct. In particular, check that the visa says something to the effect of "valid for the Schengen States" (usually written in the language used by the embassy that issued the visa; for example, États Schengen). The validity dates must match your original travel dates and not expire earlier. Contact the application centre immediately if you notice any discrepancies (even if you applied for a multiple-entry visa, the consul may still grant a single entry visa).

If your application is unsuccessful, you'll normally be given a notice explaining the reasons for such a decision. The process and grounds for appeal vary between each application centre, but you are strongly advised to refer to the notice and address the issues outlined before returning there. Unless the refusal notice states that you are ineligible to apply for a certain amount of time, you can lodge a new application at any time (with a corresponding fee), but make sure you address the issues that caused your previous application to fail.

Keep copies of the documents you used in your application and those that will establish your purpose of visit, and be sure to bring them with you as border officers may ask to see them upon your arrival.

If you have been issued a Schengen visa but later you have been notified that the main purpose for your visit no longer exists (e.g. the conference you are scheduled to attend has been cancelled) yet you still want to pursue your trip to the other countries, then you may need to inform the application centre that issued you the visa about the change in circumstance and apply for a new visa with the pertinent application centre.

Length of stay and number of entries

The maximum of 90 days in a rolling 180-day timeframe refers also to those who can enter the Schengen area without the need to apply for a full Schengen visa. If you have been issued a multiple-entry Schengen visa with a long validity period (i.e. more than 6 months) or several single-entry visas, please be aware that you are only allowed a combined maximum stay of 90 days within a 180-day period in the Schengen area. When you apply for subsequent Schengen visas, you will need to account for your previous trips to the Schengen area to ensure you have not gone over this limit.

Pay particular attention to the validity dates and length of stay: make sure to leave before they expire (whichever comes earlier).

The validity dates simply provide the window in which you can travel to the Schengen area. If you decide to postpone and shorten your trip however, the original expiry date will still stand and you must still exit on or before this date even if the allowed number of days stated in your visa won't be totally used up by this date. The maximum 90 days in 180 is counted in a moving window of 180 days. If you stayed the 90 days at the end of your previous 180 days, you are not allowed to re-enter before 90 days have elapsed. If your previous stay was shorter you are allowed to re-enter immediately, but have to leave before the recent days of your last stay and the days of your current stay add up to 90 (in the past 180 days).

If you were given a multiple-entry visa, the number of days indicated on the visa will refer to the total amount of time you can spend in the Schengen area, regardless of the number of entries you plan to make or are allowed to make, in a six-month period or the period stated in the visa – whichever is shorter. Hence, if you are given a multiple-entry visa valid for three months but the length stay only allows 10 days, the 10 days won't be reset by you leaving the Schengen zone and returning later. In this case, if you stayed for 4 days on your initial visit but wish to come back while the visa is still valid, you can only return for a maximum of 6 days on that visa. Arrival and departure dates are included in the number of days you have stayed in the Schengen zone, regardless of actual arrival and departure time, so plan accordingly to maximize time.

Likewise, if you were only given a single entry visa for 30 days but have decided to cut your trip short by leaving only 20 days into your trip, you can no longer use that same visa any more and the remaining days you have left on that visa are forfeited (though this will not be taken against you when you apply for another visa in the future since you did not overstay). If you wish to visit non-Schengen states (e.g. UK, Ireland, Romania, Bulgaria) in between two Schengen states, make it clear in your application that you need to do so (though you may also wish to visit such non-Schengen states only before entry or after visiting the Schengen zone).

Some countries within the Schengen area, such as Spain and Portugal, offer an extension to the Schengen visa (or to the right to stay), valid for that country only. This allows staying longer than the 90 days period in the Schengen area without getting a long term visa. The extension requires a valid reason and the usual paperwork on sufficient funds etc. You might have to leave without entering any other Schengen country, as they probably will count your extended stay as part of the 90 allowed days.

Entering the Schengen Area

Unlike in most other countries, incoming passengers are normally not required to fill-in any additional paperwork to present to passport control officials.

Just like with other visas, a Schengen visa does not automatically entitle you to enter the Schengen area. As such, you must still demonstrate to passport control officers that you are genuinely entitled to the visa you were issued. Even if you possess a valid visa, actual entry may still be denied if you are unable to satisfy the border officer's questions or requests to see documents.

At most checkpoints, two sets of lanes are provided: one for EEA/Swiss nationals and another for all other passport holders. In some countries, the main airports may also provide a premium lane for eligible passengers (usually those who travel in first and business class); your airline will hand you a voucher which you will show to the staff upon arrival (ask your airline for more information).

Non-EEA travellers need to provide their biometric fingerprints at the point of entry.

Do not assume that border officers at the Schengen area states have access to the databases of other member states (they generally don't). Make sure to get a stamp put into your passport. If you are a non-EU/EFTA national (even if you are visa-exempt, unless you are Andorran, Monégasque or San Marinese), make sure that your passport is clearly stamped both when you enter and leave the Schengen Area with all the pertinent dates visible. Without an entry stamp, you may be treated as an overstayer when you try to leave the Schengen Area; without an exit stamp, you may be refused entry or experience more intense questioning the next time you seek to enter the Schengen Area as you may be deemed to have overstayed on your previous visit. When you need another visa in the future, the application may be refused or you may experience further prolonged processing and scrutiny. If you cannot obtain a passport stamp or the ink is not too visible, make sure that you retain records such as boarding passes, stamps of passports from other countries, transport tickets, financial documents and attendance records at work or school, which may help to convince border inspection staff that you have stayed in the Schengen Area legally.

By plane

When travelling through a Schengen airport, flights are separated into Schengen and non-Schengen flights, similar to domestic and international flights elsewhere. This means if your first flight originates from a non-Schengen country but you are connecting via a Schengen airport to another Schengen country, you must clear passport control at the first airport you travel through within the Schengen area. Similarly, if your first flight is travelling from one Schengen airport to another Schengen airport and you are then connecting to a flight to a non-Schengen country, you must clear passport control at the last airport you travel through within the Schengen area. When a connection is inevitable, always consider the connection times and the potential for queues at passport control when booking your flights. Also consider the particular European culture you are dealing with at the connection airport. For example, a layover of only 75 minutes is more than sufficient to connect between Schengen and non-Schengen flights at Munich, which explains why Lufthansa makes such connections available for booking, but may not be enough in some other parts of the Schengen Area.

Baggage is transferred automatically between Schengen and non-Schengen flights, and vice versa, meaning that you only need to worry about the queues at passport control.

Getting around the Schengen zone

Once you are allowed into the Schengen zone, you can generally travel to any member state without having to go through formal passport control procedures again. Certain uncommon types of visas are exceptions, restricting you to the member state that issued the visa.

Some countries, like France, Italy and the Netherlands require people to declare their presence to relevant local authorities even if they arrived from another Schengen member state. Sometimes this is a requirement for all, sometimes only for non-EU/EEA/Swiss nationals, sometimes there is a formal requirement not followed up in practice. The registration may be taken care of by the accommodation you are staying at upon check-in, but otherwise you will have to visit the relevant authorities yourselves. Consult the Wikivoyage pages of the individual countries as well as the websites of their respective immigration authorities for more information.

Some countries have special rules in place for yacht visitors; in particular, Greece is a difficult country to visit with a yacht with a non-EU flag.

The Schengen agreement also has provisions for allowing individual member states to temporarily reinstate border controls in certain circumstances. These have included large sport events, important international meetings, the influx of refugees 2015–2016 and the Covid-19 pandemic. In addition, international ferries and flights may carry out their own checks, independent of those by border authorities.

Police and the border guard may check your immigration status also far from the border. Hence, you are strongly advised to carry your passport or some other form of ID that establishes your legal right to be in the Schengen area with you. Whether there is a legal requirement to do so varies between countries. This especially applies for Romania and Bulgaria, which despite being EU member states, are still continuing passport checks on its land borders.

Norway, Switzerland, Iceland, and Liechtenstein, while in the Schengen area, are not in the European Union and, accordingly, customs controls are in effect for all arriving travellers, regardless of point of origin. On some borders the controls are lax and you may have to find a customs official yourself to declare goods needing customs clearance. Åland, while a member of the EU and Schengen as part of Finland, is not a member of the tax union and you should thus declare some imports, even when there is no customs where you happen to pass the border. Similar considerations apply to the Channel Islands and some other areas.

When crossing the border by train, customs officers may enter the train; and when crossing by car, customs officers may stop your vehicle and inspect it. Customs controls can happen far from the border.

Check the following websites for more information on customs declaration requirements:

EU
Norway
Switzerland^{[dead link]}
Iceland^{[dead link]}

Finally, even within EU-Schengen states where customs checks are not carried out on importing or exporting goods, customs authorities of individual EU-Schengen states may still carry out checks to ensure that prohibited or controlled items (e.g., illegal drugs, firearms) are not transported across the border.

By plane

When using a plane to travel between two airports within the Schengen area, it will be as if you are taking a domestic flight. One odd difference from airports in the Americas is that some of the small Schengen area airports do not maintain physically separate baggage claim areas for Schengen and non-Schengen flights. Rather, they have a single baggage claim area, and then have one exit for Schengen flights and one exit through customs for non-Schengen flights. Arriving passengers must pay attention to the signage and walk towards the correct exit. These airports get so few flights that usually only the appropriate exit is actually open. When Schengen and non-Schengen flights arrive at almost the same time, the airports will post staff to check boarding passes to make sure non-Schengen passengers exit through customs.

If transiting through an airport in one of the non-EU Schengen countries from one EU country to another, you may not be required to clear customs in the transiting airport.
