San Antonio International Airport
San Antonio International Airport


San Antonio International Airport is located on Airport Boulevard, approximately fifteen miles from the downtown area. Major freeways provide easy access to the airport. The airport is comprised of three runways and spans some 2,600 acres.

History of San Antonio Airport

This airport was originally established in 1941 following the purchase of 1,200 acres of undeveloped land by the City of San Antonio. This area, north of the city, is now part of the Uptown District. At the time, the project was known as the San Antonio Municipal Airport. With the onset of World War II, the yet to be completed airport was needed for government service and was officially opened in July of 1942. The United States Army Air Forces quickly began to use Alamo Field as a training base. Reconnaissance personnel from the 77th Reconnaissance Group who would later serve overseas began to train at the field. By the conclusion of the war, the airfield was no longer required for military service and was subsequently turned back over to the City of San Antonio.

The terminal formerly known as Terminal 2 was constructed between the years of 1951 and 1953. During this time, the FAA control tower as well as a baggage claim area was also built. A new satellite concourse, featuring eight jet bridge gates, was constructed for the HemisFair in 1968.

The airport’s first master plan was adopted in 1975 and included plans for a spacious new parking garage as well as a new terminal. Following the completion of Terminal 1, now known as Terminal A, in 1984, the airport went from a mere eight gates to 27 gates. Two years later, a new control tower was constructed.

After almost twenty years, it became necessary to develop a new Airport Master Plan that would set the airport on the path for the 21st century. The 1994 master plan included a number of significant updates to the airport, including an additional 3,000 parking-space garage, improved airport access, and improved concessions. In addition, two new terminals were added to the plans to replace the ancient Terminal 2. These plans would bring the gate capacity at the airport to 35.

In November of 2010, Terminal 2 was finally closed and Terminal B was opened. At this time, the former Terminal 1 became known as Terminal A. By the end of 1999, the airport had witnessed 3.5 million passengers.

Terminal Information

Today, two terminals continue to serve the needs of passengers at the San Antonio International Airport. Terminal A, originally opened in 1984, features a 16-gate concourse. This terminal also contains the U.S. Customs Federal Inspection Station. A modernization project is planned for Terminal A. Terminal B contains an eight-gate concourse. Directly across from Terminal A is a two-level parking garage as well as a five-level parking garage. One of the stark differences that do exist between the San Antonio International Airport and other major airports is that it is not possible to go between the two terminals in the security level. Instead, passengers must leave one terminal and then enter the security area again before proceeding to the other terminal.
