San Antonio International Airport: A Catchment Success Story with a Twist!
You might be surprised to learn that despite its proximity to Austin-Bergstrom International Airport, San Antonio International Airport has an impressive 69% market share in its core catchment area. That's right! San Antonio is a dominant force, even though it's just a stone's throw away from Austin. But here's where it gets interesting: when it comes to passenger leakage, Austin-Bergstrom captures a significant 77% of those travelers, with Houston George Bush Intercontinental Airport taking the remaining 17%.
Now, let's dive into a fascinating revelation. On the top three routes where San Antonio is losing the most passengers to Austin (Los Angeles, New York, and San Francisco), there's a notable concentration of passengers living close to San Antonio. It's almost as if they're just a hop, skip, and a jump away from choosing San Antonio over Austin!
But wait, there's more! San Antonio Airport has been making some serious moves. In July 2025, it received a whopping $13.3 million grant from the US FAA's Airport Infrastructure Grants program. This funding is a game-changer, supporting the airport's new terminal development, which is currently in its fourth phase of construction. The terminal project is massive, with over 800,000 square feet of space, concessions galore, and up to 17 gates. It's scheduled for completion in 2028 and is the linchpin of the Elevate/SAT expansion, a $2.5 billion program to improve the airport's infrastructure.
