The airport handles roughly 10.8M annually and is a major operating base for Southwest Airlines. Travelers connecting through SAT have access to 3 airport lounges spread across 2 terminals or concourses, including some of the most highly regarded card-issued and airline-operated lounges in the United States.

The airport sits in San Antonio, Texas and is well connected to the surrounding metropolitan area by interstate, light rail, and rideshare. Most travelers heading to a lounge should pass through TSA security at their assigned terminal first, then follow signage for the relevant concourse. Plan to arrive at the lounge entrance at least 60 to 90 minutes before boarding to take full advantage of the food, drink, and shower facilities.

Lounge programs available at SAT include American Airlines Admirals Club, Priority Pass, The Club Airport Lounges. Below you'll find each individual lounge with its terminal, operator, access rules, and a current amenity list.

Insider tip: when planning a long connection at SAT, verify your boarding pass shows the correct terminal — and whether the lounge you plan to visit is post-security in your concourse. Some networks operate multiple locations within the same airport, and entering one and exiting through security to reach another can cost you 30+ minutes during busy periods.

For travelers planning a longer layover at SAT, lounges with shower suites and quiet rooms are highlighted in the listings below. Standard guest policies apply for each program; expect to pay $45–$75 for additional guests at most card-issued lounges. Day-pass options vary, so confirm pricing with the operator before relying on a paid walk-up.
