What You'll Learn

San Antonio Airport System (SAAS)
The San Antonio Airport System (SAAS) is comprised of two airports: San Antonio International Airport and Stinson Municipal Airport. The former, founded in 1941, is located in Uptown Central San Antonio, about 8 miles (13 km) north of Downtown. It has three runways, covers 2,305 acres (933 ha), and is the 44th busiest airport in the United States by passenger traffic, averaging 260 daily departures and arrivals at its 27 gates. The airport currently serves 14 airlines flying non-stop to 45 destinations in the US and Mexico.
San Antonio International Airport was established when the City of San Antonio purchased 1,200 acres (490 ha) of undeveloped land for a project initially called "'San Antonio Municipal Airport." The airport's name was changed to its current one in 1944, and it has since undergone several expansions and renovations, including the addition of Terminal 2 in the 1950s, and a new satellite concourse built for HemisFair '68. The original Terminal 2 was eventually closed and demolished between 2010 and 2012, with the opening of Terminal B.
Stinson Municipal Airport, on the other hand, is the second oldest continuously operating general aviation airport, having been built in 1915 by the Stinson Family.
The SAAS has recently embarked on a significant development program, with a $1.4 billion price tag. This includes the construction of a new 17-gate terminal, a ground transportation center, and the expansion of elevated roadways. The project is being managed by Colorado-based company Hensel Phelps, one of the largest aviation construction contractors in the country. The new terminal is expected to enhance the efficiency and capacity of the airport system, accommodating the growing aviation demands in the region.

Airport history and development
San Antonio International Airport (SAT) is an international airport in San Antonio, Texas, United States. The airport was founded in 1941 when the City of San Antonio purchased 1,200 acres of undeveloped land north of the city limits for a project called "San Antonio Municipal Airport." Due to World War II, the airport was not fully finished until after the war. In 1944, the airport's name was changed to San Antonio International Airport.
The first airline to serve the airport was Braniff Airlines in 1943, followed by American Airlines in 1944. In 1951, construction began on Terminal 2, which was completed in 1953. The terminal included a new FAA control tower and a baggage claim area. In 1959, the terminal was expanded with new east and west wings, and in 1968, an eight-gate satellite concourse was added to handle visitors to HemisFair '68.
In June 1971, Southwest Airlines chose San Antonio International Airport as one of its first three destinations, along with Dallas and Houston. In 1975, the city adopted its first Airport Master Plan, which included plans for a new parking garage and a new terminal (now called Terminal A).
In 2002, ST Engineering, known as SAA (San Antonio Aerospace), purchased facilities previously owned by Dee Howard Aircraft Maintenance during their bankruptcy. SAA provides maintenance, services, and aircraft leasing operations for passenger and cargo airlines.
In 2010, Terminal 2 was closed and demolished, and Terminal B was opened. In 2013, SAT Customs and Border Protection became a Global Entry enrollment center. In 2023, construction began on a Ground Load Facility connected to Terminal A, expected to be completed by 2025. The facility will include ground load gate positions, retail, and food options, catering to ultra-low-cost airlines.
