William P. Hobby Airport (IATA: HOU, ICAO: KHOU, FAA LID: HOU) is an international airport in Houston, Texas, 7 miles (11 km) from downtown Houston. Hobby is Houston's oldest commercial airport and was its primary commercial airport until Houston Intercontinental Airport, now George Bush Intercontinental Airport, opened in 1969. After the opening of Houston Intercontinental, Hobby was closed for several years before it became apparent it needed to be reopened. It became a secondary airport for domestic airline service as well as a regional center for corporate and private aviation.
Houston Hobby is a major focus city for Southwest Airlines, which operates international and domestic flights from HOU. Houston Hobby is the fifth largest airport in Southwest's network as of December 2017. Hobby is classified as a medium-sized airport, and is currently the third-largest of this airport classification in terms of passengers (behind only St. Louis and Nashville, in that order). Southwest opened its first international terminal at Houston Hobby, and began service from Houston Hobby to Mexico and Central and South America on October 15, 2015.
The airport covers 1,304 acres (528 ha) and has four runways. Its original art deco terminal building, which was the first passenger airline terminal in Houston, now houses the 1940 Air Terminal Museum.
