Buses cover more of the country than trains and have more frequent departures; and unlike air travel, there is no hassle of security. Although it is not the fastest way, competition between the various operators makes bus travel generally inexpensive. It is even possible to obtain a trip between two cities for as little as $1.
Most intercity bus services use the interstate highway system for the majority of their routes, thereby taking the fastest route they possibly can.
Most long-distance buses are comfortable. Seats are spacious and sometimes have a small flip-down table, like on an airplane. On-board toilets for passengers are also more common than not. Some bus companies show movies on board. Power outlets and Wi-Fi for passengers' use is increasingly the norm. You can also bring food and drink onboard.
Shorter runs, sometimes up to several hours long, may have no intermediate stops. But on longer routes there will be scheduled stops, either in cities where passengers are picked up and offloaded and you can get off the bus for a few moments or at a truck stop where you can get off to eat and drink in a cafe or restaurant. Longer scheduled stops are usually printed on your ticket.
Even for those who fly and drive regularly there are still advantages to include bus travel with your plans. For travel within 300 mi (480 km) or to destinations with limited or no commercial air service, bus travel or driving would usually be most economical way to get there. Anything over 300 mi between metropolitan areas or across the country and you will find the cost of air travel to rival or even undercut bus fares. The exceptions for using buses over longer distances is if you plan to travel point to point across the country with the need to hop on and off frequently. To get between places not well served by commercial airlines would be to combine bus with air travel. Take the bus to the nearest city with a major airport, fly to the next city and then take another bus to the final destination. For example, if one is traveling from Arcata, California, to Key West, Florida, the round trip airfare may be $850 whereas the airfare from San Francisco to Ft Lauderdale or Miami in South Florida may be just $240 round trip. Therefore, one would take the first bus from Arcata to San Francisco; fly from San Francisco to South Florida and transfer to another bus going to Key West. This saves money on the difference in airfare, the cost of airport parking in San Francisco and the extra airport surcharges for renting a car from Ft Lauderdale. In context of this example, if you are planning to stay in Key West you can get around locally without a car! But this may not be true in other places especially if you are going to a remote locale like somewhere in the Florida keys, off of the main highway, or to the Everglades from Miami. Using buses in combination with air travel is more necessary for traveling east and west across Canada as the Canadian domestic airlines are predominantly with Air Canada and Westjet as a duopoly and with higher taxes imposed on them, domestic air travel is more expensive in Canada than in the United States. For example, for a traveler to get from Vancouver to Toronto he/she can takes a bus from Vancouver to Seattle; fly across the US from Seattle to Buffalo and then transfer to another bus going to Toronto. Same thing with travel between the U.S. & Canada and from outside the North American continent to Canada. Travel by bus from Toronto to Buffalo and fly from Buffalo to Florida or continue further south by bus into New York City to catch an international flight out of North America. The downside is that it takes more time and is less convenient, but it can save several hundreds of dollars in the difference in airfare especially if two or more are traveling together and budget is tight. Most people will still drive to the airport, rent a car from the airport or use Canadian airports because it is quicker and more convenient to get to there.

There are additional companies marketing as a "Chinatown bus" in the West Coast and in Canada. Because they're cheap, a number of them have questionable standards of safety and do not provide great service. Some had even gone out of business or have been being shut down by regulators as a result while others crop up to take their places. See GoToBus.com and ILikeBus.com to look them up and buy tickets.

The above list is not complete as there are numerous publicly operated buses as public transportation in urban and rural areas and privately owned & operated (for profit) companies traveling across longer distances. Some cross state lines (or international lines to Canada or Mexico) while others operate within a single state. See By bus under Get in, in a city or town article and under Get around and/or Get in, in a state article for a list of additional bus companies traveling to or through that location. A number of the Trailways and other bus lines have interline agreements with Greyhound Lines & each other to allow travelers to buy another bus company's ticket on Greyhound.com or their respective websites for contiguous travel. Under such agreements they usually use shared bus station facilities but not always the case either.
Tickets can often be purchased online with many of the bus companies, some offering discounts for buying online while others require the tickets can only be bought online. Others with established stations and stops at hotels and convenience stores may sell the tickets at the station or through the store or hotel front desk on a contract basis. The companies with only a curbside stop may require tickets be purchased online, printed and presented to the driver prior to boarding as the drivers cannot accept payment or carry any cash. See their websites as to what the policy may be.
Layovers are a part of longer bus journeys. Some last only 10 minutes, but they can be several hours long. If you have the energy, longer layovers can be used to explore the city. As bus travel is seen by most Americans as a form of cheap transport for those too poor to afford a car or plane tickets, do not expect much in the way of amenities in bus stations.
In many cities, many of the train stations are being converted to include bus stations for local city buses and intercity bus lines (Greyhound, Megabus, etc.) in a shared facility. Even in cities or towns not served by Amtrak trains they had also combined local public transportation and intercity buses in a shared transfer station. If arriving into a city by plane there are also long distance buses and van shuttles at the airport arrivals zone for direct travel to another city or town over 60 mi (97 km) from the airport terminal, thus saving a trip into town to reach the bus station. In other places each company maintains their own separate stations or they subcontract a convenience store/gas station; truck stop, travel agency, restaurant or hotel to the sell the tickets and serve as a de-facto bus station. In other locations or with some companies they only have a curbside bus stop with a sign at a street corner or in a parking lot while the surrounding businesses have nothing to do with the bus company. Therefore, you must prepay and preprint the ticket online before going to the bus stop as the drivers cannot accept cash or any form of payment. The bus stations or stops can be in sketchy neighborhoods and therefore you should plan to arrive before dark when possible and plan to use a taxi, ride share service (Uber, Lyft, etc.); or arrange for someone to pick you up prior to arrival. Even in a shared station with local public transportation, the station can be unmanned and all outdoors in a sketchy neighborhood.
If you plan to use the local public transportation, find out where the marked bus stop is, which routes you need, how frequent that bus goes by and which side of the street you need to wait at. In many cities the Greyhound station/stop is in or next to the transit center for multiple routes of the local city or county buses. In some places the local buses may quit running M-Sa after 6:30PM or 7PM evenings and no service all day Sundays and holidays while in bigger cities they tend to operate longer hours every day. Use the maps provided by Google or Wikivoyage to determine the nearest bus stop location and the trip planner program on the transit agency's website to see which buses or trains to take to get to there. Know the fare required in advance of arrival. Local bus fares are typically paid with exact change to the cash box as the driver does not make change for the difference in overpayments. In rural locales and small towns there may not be marked bus stops either but rather flag down the bus or the stop must be prearranged in advance (usually 24 hours prior). In most other rural and remote locales there may not be any local public transportation available either.
The available amenities inside the stations varies with some offering a restaurant and gift shop while others may have nothing more than vending machines for snacks and drinks. There could be individual TVs on the armrest of each seat or one big TV mounted on the wall for everybody in the room to watch. There can even be a time limit on how long one can be in there before being asked to produce a ticket or leave in order to keep the homeless from taking shelter inside. Some stations like the Greyhound station in Chicago have lockers but most don't. Unattended bags are more likely to be confiscated by security than to be stolen. Try to separate your valuables into a smaller bag you can always keep with you and not tempt fate. In other places there are also car rental offices or desks (Avis, Hertz, Enterprise) inside or somewhere next to or nearby the bus station. In places where the bus station is in a shared station with local public transportation, the facilities are usually very basic with only a series of bus stops lined up, one next to another, on several islands in an open lot.
Occasionally drivers may point out a convenience store or fast food restaurant nearby the bus station but most don't except to announce the arrival to the stop and the re-boarding instructions for onward travel. If you look up where your stops are before the journey, you might be able to find better and cheaper food, drink, and entertainment; accommodations or local city bus routes going by the bus station or stop. If you don't, still keep your eyes peeled for gas stations, restaurants, accommodations and city bus stop signs or shelters near the bus station.
If you choose to spend your layover time sampling nearby bars do not get drunk as you will not be allowed on the bus. Even the smell of alcohol in your breath may be enough for a driver to disallow you back on the bus.
Generally, the few rules imposed on bus travelers are very basic and largely common sense. Smoking and alcohol consumption are always forbidden. Some buses have signs banning eating and drinking, but this is rarely enforced; if you do eat or drink try to clean up after yourself. Try to keep noise to a minimum - no-one wants to hear other people's conversations, no matter how fascinating you think they are. Unlike air travel, security checks are rare, but there are occasional inspections for 'banned' items, though items that are obvious hazards such as firearms may not be brought on board. Each company has its own guidelines regarding live animals.
- Driving in the United States Driving offers the most flexibility and freedom to go wherever and whenever you want and is the most preferred method with many folks especially when three or more are traveling together.
- Air travel in the United States Can be the most economical and quickest way to get across longer distances. A flight across the nation from New York to Los Angeles is 5-6 hr vs. 3 days (65-72 hr) on a bus for the same amount of fare. Flying is (almost) a must for travel to Alaska, Hawaii and Puerto Rico.
