airport in Houston, Texas, United States

George Bush Intercontinental Airport (IAH IATA) is the main international airport of Houston and a major gateway into Texas.


Until its opening in 1969, William P. Hobby Airport was the main airport of the region, serving quite a bit of intercontinental service. While Intercontinental was meant to replace Hobby, it ended up supplementing it to the point that there was even planes flying between the two as "cross-town shuttles" in the 1970s and 1980s.

In the 1980s and 1990s, Continental Airlines established a dual hub system with IAH and Hobby, and United eventually inherited the Intercontinental hub when they merged. In fact, this airport is United's largest hub and also hosts the airline's (and one of the world's) longest flight (Houston - Sydney). Houston is also United's main hub for Latin America, so it has nonstop flights to most cities in Mexico, in addition to Central and South America.

Note: If you're traveling with Southwest they only land and take off at the William P Hobby Airport (HOU IATA), another airport south of and closer to downtown and midtown Houston. Southwest does not offer flights into or out of George Bush International Airport. American Airlines and Delta/Delta Connection offer flights to both airports.

There are five terminals at the airport - Terminals A-C for domestic flights, and Terminals D and E for international flights.

United is almost in every terminal, speaking to the size of the hub.

  Terminal A

  Terminal B
  Terminal C
  Terminal D
Aeromexico, Air China, Air France, Air New Zealand, All Nippon Airways, Avianca, Bahamasair, British Airways, Emirates, Ethiopian Airlines, EVA Air, Interjet, KLM, Lufthansa, Qatar Airways, Singapore Airlines, Turkish Airlines, VivaAerobus, Volaris
  Terminal E

There are some interesting fifth-freedom flights here - Singapore Airlines operates a Houston-Manchester-Singapore flight, and Air China operates a Beijing-Houston-Panama City flight.


All international arrivals except preclearance flights must go through customs. While the building for that is techinally part of Terminal E, in practice it is shared by both international terminals D and E (terminals that are already quite interconnected, sharing a check-in area), which have bridges to the international arrivals processing area.


For those arriving on international flights, Immigration and Customs process usually takes 15–30 minutes, but can take over an hour at peak times. The busiest times are in the afternoon and evening.


Like all airports in the United States, there are no special transit facilities for international transfers. That means that if you are arriving from an international flight and have an immediate connection, you will still have to pass through Customs and Immigration. For details of entry and visa requirements see get in section of United States page.

Ground transportationEdit

The light rail hasn't been extended to the airport yet, so car travel is probably your best option

By carEdit

From Downtown Houston the Hardy Toll Road is usually the easiest way to reach the airport however an EZ Tag is required as all tolls are collected electronically. Alternatively taking the Eastex Freeway (I-69/US 59) to Will Clayton Parkway is another good option especially for visitors. Avoid taking the North Freeway (I-45) to the airport if possible as it is prone to traffic congestion.

By rental carEdit

Another option is to pick up a rental car at IAH. To do so, you will take the shared shuttle from the airport terminal to the consolidated car rental facility located at 17330 Palmetto Pines. The following companies are inside the facility:

EVA Air operates shuttles for its passengers between the Richardson Tapioca House in Dallas Chinatown and the airport, as well as a service to and from Austin (only available for Laurel class passengers).


There are several different levels of pricing for parking at the airport depending on proximity to the terminal and level of service. In addition, there are private parking services located near the airport that will drop you off at a terminal like the Parking Spot, Fast Park & Relax, and Park 'N Fly.
