San Antonio International Airport opens Terminal A expansion with three ground-level gates and updated amenities

Expanded capacity arrives ahead of a much larger terminal project

San Antonio International Airport has opened an expansion to Terminal A designed to add near-term capacity and improve the passenger experience while a new terminal remains under construction. The newly completed addition centers on a ground load facility built south of Terminal A, creating three new ground-level boarding gates and associated holdroom space.

The facility adds about 37,000 square feet and is intended to support operations that board passengers at ground level rather than through jet bridges. Airport planning documents describe the expansion as part of a broader terminal development program that aims to address gate constraints and congestion during peak travel periods.

What changed for travelers in Terminal A

The Terminal A expansion is structured around additional seating and waiting space and a set of passenger-focused upgrades commonly associated with new gate areas. Project descriptions tied to the ground load facility have outlined features such as dual-level seating areas, additional concession capacity and upgraded power access for devices.

• Three additional ground boarding gates connected to Terminal A operations
• Expanded holdroom space intended to reduce crowding near boarding areas
• Space planned for expanded food, retail and passenger services

The airport has also been rolling out new concession offerings across existing terminals, including additional locally owned restaurant outposts scheduled in phases through 2026. Those changes are separate from the new terminal build but align with the airport’s wider modernization push.

How the expansion fits into the airport’s long-term redevelopment

The Terminal A work is one component of a multiyear, multibillion-dollar redevelopment effort that includes construction of a new terminal complex commonly referred to as Terminal C. City and airport materials describe that terminal as a major capacity and amenities expansion, with plans for up to 17–18 gates, a modern federal inspection station to support expanded international service, and substantial increases in concessions and passenger circulation space. The project has been publicly framed as a response to sustained passenger growth over the past decade, even as annual totals can fluctuate year to year.

Airport planning materials describe the Terminal A ground load facility as a near-term capacity addition while the next-generation terminal is built.

What happens next

With the Terminal A expansion now open, construction activity is expected to continue around the terminal district as enabling projects advance for the new terminal and related infrastructure. Travelers should anticipate an extended period of phased work across the airport footprint, with the newly opened gates and waiting areas intended to provide added operating flexibility during that transition.

Airport timelines published by the city and airport have pointed to the new terminal opening in 2028, positioning the Terminal A expansion as an interim step to add capacity and improve comfort before the larger build is completed.
