About San Antonio International
San Antonio International is a mid-sized hub that punches above its weight for international travel, especially to Mexico and the Caribbean. Southwest Airlines dominates here with multiple daily flights, but you'll also find United, American, and budget carriers like Frontier and Spirit. The airport handles about 10 million passengers annually and has undergone steady modernization. It's smaller and less congested than Dallas or Houston, which means shorter lines and faster security — a real advantage during peak travel times. SAT serves as a major gateway for leisure travelers heading south, with competitive pricing on Caribbean routes and excellent connections to Mexico City, Cancun, and Puerto Vallarta.
Terminals & Airlines
SAT operates a single modern terminal building completed in 2008, so navigation is straightforward. Southwest operates from the west side of the terminal (Gates 1-15), while American, United, Frontier, and Spirit share the east side (Gates 16-32). International departures and arrivals run through the same main terminal with a dedicated international corridor. No separate terminals means you won't waste time wandering—security lines are the only real bottleneck.
Getting to the Airport
VIA (San Antonio's public transit) runs Route 5 from downtown to the airport every 30-45 minutes ($1.30 one-way, 35-40 minutes from River Walk). Uber/Lyft runs $12-18 from downtown depending on surge pricing (15-20 minutes). Taxi from downtown is flat-rate $25 (negotiate before getting in). Rental car shuttles are located on Level 1 baggage claim. Driving yourself? Parking is $3/hour in short-term (reasonable for a day or two) or $18/day in economy lot. The airport is only 8 miles north of downtown, so any transit option is quick.
Parking
Short-term parking is $3/hour, capped at $24/day—actually competitive if you're only gone 1-2 days. Economy lot (long-term) is $18/day but fills up during peak season (April-May, November-December). Book valet through the airport website for $27/day, which saves 10 minutes vs. hunting for spots. Off-site lots like ParkSAT charge $12/day but require a shuttle (worth it only for trips longer than 5 days). Avoid the daily rate trap: if you're going longer than 8 days, buy a long-term pass directly rather than hourly.

Pro Tips for Flying from San Antonio
Southwest's dominance at SAT means frequent flash sales to Caribbean and Mexico destinations—set price alerts for routes like SAT-SJU (Puerto Rico) and SAT-CUN, which routinely drop to $89-119 round-trip.
The airport WiFi (SAT-Free) is actually solid and covers the entire terminal, so you can work or track price drops from the gate area without buying airport food.
Frontier and Spirit use Gate 22-25 at the far east end—if you're flying a budget carrier, arrive early for overhead bin space; these gates can get crowded and bins fill fast.
Security PreCheck lines are usually empty here even during peak times; it's worth the $78-85 for the time savings alone if you fly 2-3 times yearly from SAT.
