San Antonio International Airport (IATA: SAT, ICAO: KSAT) is a commercial airport in San Antonio, Texas. The airport has three runways, covers 2,600 acres, and its elevation is 809 feet above sea level. SAT is a Class C airport.
In 2006, San Antonio International Airport handled 8,031,405 passengers, up 8 percent from 2005 and breaking the previous record of 7,437,290 set in 2005. SAT averages 280 daily departures and arrivals at its 27 gates, which serve 21 airlines flying to 43 metro areas, including Mexico City and Monterrey. The airport's top-ranked destinations are Dallas, Houston, Las Vegas, Chicago, Baltimore, New York, Los Angeles, Phoenix, Atlanta and Washington, D.C. As of December 2006, Southwest Airlines is the airport's largest passenger air carrier, enplaning 35.24 percent of the airport's total passengers. American, Continental, and Northwest are the next three largest carriers. From February to September 2006, United Airlines maintained a "mini-hub" (which it affectionately called a 'hublet') at the airport with flights to 12 cities in conjunction with their partner Trans States Airlines. Trans States Airlines redeployed their aircraft elsewhere, eliminating service to seven cities. ExpressJet Airlines currently operates a hub at the airport. Mexicana recently celebrated 50 years serving the airport.
The airport is currently undergoing a major, multi-million dollar expansion project which will add new terminals and parking facilities. The ultimate master plan for the project will increase gate capacity to 35. In addition, construction projects involving Interstate 410 and U.S. Highway 281 will improve access to the airport. (The airport sits near the northeast corner of the I-410/US 281 intersection.) Future plans also call for Stinson Municipal Airport, currently serving general aviation, to become the city's secondary commercial airport.
