George W. Bush Intercontinental Airport (IAH)

2800 N. Terminal Road

About 23 miles north of downtown off Interstate 69, Intercontinental has been Houston’s major commercial international airport since it opened in 1969. It is a hub for United Airlines, which accounts for more than 75% of the airport’s passengers, many of whom are connecting on east-west U.S. domestic routes or using the airport as a gateway to/from Latin America destinations. The drive to downtown Houston takes about 25 minutes in normal traffic.


Bush Intercontinental Airport has five terminals, labeled A, B, C, D and E. All of the terminals are interconnected post-security via an automated train system called the Skyway. There is also a subway that connects the terminals, pre-security. International arrivals and departures use gates on the D and E concourses.

Terminal A is shared by Air Canada, Alaska, American, Delta, Frontier, JetBlue, Spirit, Southwest and United; Terminals B, C and E are used exclusively by United, and Terminal D is used by international airlines Aeroméxico, Air France, All Nippon Airways (ANA), Avianca, British Airways, El Al Israel, Emirates, Eva Air, KLM Royal Dutch, Lufthansa, Qatar Airways, Turkish and VivaAerobús.

Ground transportation options include taxis, app-based rides, and reserved car and limousine services and shuttles, all of which can be found outside baggage claim at Terminals A, B, C and E. Buses, including Houston Metropolitan Transit Authority‘s Route 102 to downtown as well as other lines to neighboring cities, depart from outside baggage claim of Terminal C.

To/From Tucson Connections

United Airlines flights arrive and depart at gates on the A, B, C and E concourses at Bush Intercontinental Airport. Connecting passengers arriving on domestic flights, or international flights that were pre-cleared by U.S. Customs at their departure airport, can use the Skyway automated train system between terminals without exiting the TSA secure area. Connecting passengers arriving on international flights who clear U.S. Customs at Houston will find the TSA’s international re-screening area can be chaotic and slow when it’s busy. Also PreCheck is not available. An often more efficient alternative is to exit the international arrivals area as if you are a local passenger leaving the airport. Once in the International Arrivals Hall take the escalator up to the ticketing level where there is a TSA checkpoint with PreCheck. United has check-in counters and baggage claim in each of the four terminals it uses.

William P. Hobby Airport (HOU)

7800 Airport Blvd.

Less than 10 miles southwest of downtown Houston via Interstate 45, Hobby Airport began as a private landing strip in 1927. It was acquired by the city of Houston in 1937 and was Houston Municipal Airport until 1967 when it was renamed in honor of a former Texas governor. The airport served as Houston’s primary airport until 1969 when Intercontinental Airport opened north of the city and the commercial airlines moved there. A new intra-Texas airline thought the location closer to downtown was better suited to its business model and on June 18, 1971 jet airlines returned when Southwest was launched flying passengers to three cities: Dallas (where it used Love Field), Houston Hobby and San Antonio. Now one of the four largest airlines in the United States, Southwest stayed at Hobby and accounts for more than 90% of the airport’s passengers. In 2015, Southwest helped pay for an expansion of the airport that added a concourse for international flights.


The terminal is one building with two concourses. Gates 20-32 and 40-51 are on the Central Concourse and Gates 1-5, which are also the international gates, are on the West Concourse. Both concourses are connected post-security.

Ground transportation options can be found outside baggage claim. Taxis are at Curb Zone 2, app-based ride services are at Curb Zone 5 and shuttles and Houston Metropolitan Transit Authority buses are at Curb Zone 3. Limousine and car service drivers can be met inside baggage claim.

 To/From Tucson Connections

Southwest Airlines flights arrive and depart Hobby Airport at gates 1-4, 20-27 and 40-51. Passengers making connections can reach all gates without exiting the TSA secure area.

Visit Space City

Houston is in Texas so of course it’s big. More than 7 million people live in the metro area, or ‘the 713,’ as it’s sometimes called, referring to its phone area code. Houston is more racially and ethnically diverse than the nation. Boosters like to point to the numerous Fortune 500 and Fortune 1000 companies that are headquartered in the area, making it an economic center for energy, manufacturing and aeronautics. For better or worse, Houston is also the only major city in the United States that has never had zoning ordinances.

Did You Know …

The closest seawater in Houston is down

The average elevation of downtown Houston is just 50 feet above sea level and the area’s highest point is 125 feet so you would reach seawater quickest by digging.  If you prefer your ocean with a beach, the nearest is Surfside Beach 65 miles away.
