The Greater Houston metropolitan region is served by George Bush Intercontinental Airport, an international airport in Houston, Texas, in the United States. In 1997, Houston native and 41st President of the United States George H. W. Bush had the airport, which had previously been known as Houston Intercontinental Airport, renamed in his honor.

It is the second busiest airport in Texas overall, the 12th busiest in the United States for total passenger traffic, and the busiest airport in Texas for the volume of foreign passenger traffic and the number of international destinations.

In order to protect the site of Bush Intercontinental Airport until Houston could come up with a plan for a new airport to replace William P. Hobby Airport, a group of businessmen from Houston bought it in 1957. (at the time known as Houston International Airport). Although the name Jethro was no longer used in official planning documents after 1961, the airport's eastern entrance was named Jethro Boulevard. Most of Jetero Boulevard was later renamed Will Clayton Parkway. The holding company for the land was named the Jet Era Ranch Corporation, but a typographical error transformed the words "Jet Era" into "Jetero," and the airport site subsequently became known as the Jetero airport site in Houston .

Domestic scheduled passenger flights were run by American Airlines, Braniff International Airways, Continental Airlines, Delta Air Lines, Eastern Air Lines, National Airlines, and Houston-based Texas International Airlines, originally known as Trans-Texas Airways, at the time of IAH's debut in 1969.

In 1997, Houston native and 41st President of the United States George H. W. Bush had the airport, which had previously been known as Houston Intercontinental Airport, renamed in his honor. IAH has five runways with a total land area of 10,000 acres (4,000 hectares).

A Skyway automated people-mover above ground and a railway beneath connect all five terminals of IAH (Subway).

Up until it opened in 1969, William P. Hobby Airport served a significant amount of intercontinental service as the primary airport for the area. While Intercontinental was intended to take the place of Hobby, it actually supplemented it to the point where, in the 1970s and 1980s, there were even flights operating between the two as "cross-town shuttles." Continental Airlines created a dual hub system with IAH and Hobby in the 1980s and 1990s, and United eventually took over the Intercontinental hub when they amalgamated. In actuality, this airport serves as United's principal hub and is the starting point of the airline's (and one of the longest) trips (Houston - Sydney). In addition to Central and South America, Houston serves as United's primary base for operations in the region, with nonstop service to the majority of Mexican cities.
