William P. Hobby Airport (HOU)

William P. Hobby Airport serves as Southwest Airlines' major Texas hub and Houston's secondary airport, featuring a compact yet efficient layout that has been significantly expanded and modernized to include international operations. The airport operates through a main terminal building with two primary concourses: the domestic concourse serving Southwest's extensive domestic network and other carriers, and the newer International Terminal (opened 2015) which accommodates Southwest's international flights to Mexico, Central America, and the Caribbean along with other international carriers. The domestic concourse houses Southwest's primary Houston operations with numerous gates arranged in a linear configuration that allows for efficient boarding and quick turnarounds characteristic of Southwest's point-to-point service model. The International Terminal is connected to the main domestic facility via secure walkways and features dedicated customs and immigration facilities including CBP processing areas, duty-free shopping, and international departure amenities. Walking distances between gates are minimal compared to larger airports, with most connections possible within 10-15 minutes. Security processing is streamlined with separate checkpoints for domestic and international operations, featuring TSA PreCheck and standard security lanes. Wait times are typically shorter than at larger airports, ranging from 10-20 minutes during standard periods to 30-45 minutes during peak Southwest departure banks, particularly during morning and evening waves when the airline's schedule creates concentrated passenger flows. International operations have transformed Hobby from a primarily domestic airport into a significant gateway for leisure travel to Latin America and Mexico, with Southwest's low-cost international model making international travel more accessible to Houston-area residents. The international facilities include comprehensive customs and immigration processing along with connections to Southwest's domestic network for passengers continuing to other U.S. destinations. Hobby's compact design offers efficient passenger processing with amenities including restaurants featuring Texas barbecue, Tex-Mex cuisine, and Houston-area favorites, retail shops highlighting Texas products and Houston sports teams, and modern facilities including free Wi-Fi throughout, abundant charging stations, and family-friendly amenities. The airport emphasizes its convenient location closer to downtown Houston compared to Bush Intercontinental, making it attractive for business travelers and those accessing central Houston areas.
