Terminal A
The larger terminal, used by Southwest and most other airlines, including every international flight. U.S. Customs and Border Protection is here, so all international arrivals clear customs in Terminal A.
San Antonio International Airport (SAT) is the main airport for San Antonio, Texas, in the United States. It sits in the city's Uptown Central area, near Interstate 410 and U.S. 281, about 8 miles (13 km) north of downtown, the River Walk and the Alamo. In normal traffic the drive downtown takes about 15 to 20 minutes.
Southwest, American, Delta, United, Alaska, Frontier, Breeze and Sun Country fly nonstop to cities across the United States. Aeroméxico, Viva Aerobus and Volaris fly to Mexico City, Monterrey, Guadalajara and other Mexican cities, and Air Canada flies seasonally to Toronto.
The airport has two terminals side by side, Terminal A and Terminal B, linked inside the building. Terminal A handles most airlines and all international arrivals, and Terminal B handles American and United. A new Terminal C is under construction and is planned to open in 2028.
From the airport, most travelers head downtown to hotels along the River Walk, to the Henry B. González Convention Center or the Pearl, north to Stone Oak, or northwest to La Cantera and Six Flags Fiesta Texas.
