You know what’s wild? I just booked a flight from San Antonio to Mexico City for less than I spend on groceries. After months of tracking deals from SAT, I’ve found some seriously cheap flights that’ll get you out exploring. And no, I’m not talking about another boring trip to Vegas (though those deals are pretty sweet too). These are the best places in San Antonio to catch affordable flights that’ll actually take you somewhere exciting.

Want to spend your weekend eating fresh seafood in Puerto Vallarta’s Zona Romantica or wandering through the colorful streets of Mexico City’s Condesa neighborhood? I’ve found round-trip tickets under $200 for both. Seriously. I’ve spent way too much time hunting down these deals, and now I’m sharing exactly how you can grab them too.

#1 tip for finding cheap flights from San Antonio

Looking for cheap places to fly from San Antonio? Before jumping into all the coolest cities and airports to fly into, I want to share a quick tip to save money on airfare.

For the past 5 years, I’ve used Scott’s Cheap Flights (now called Going) to find cheap flight deals. It’s free and super easy to use. All you have to do is enter in your home airport (i.e. SAT) and where you want to go, and they’ll send you mistake fares and other ridiculously cheap flight deals.

In 2024 alone, I saved thousands of dollars thanks to their email alerts. This includes most recently, a $537 roundtrip fare from San Antonio to London. On average, I save about $300 roundtrip on selected flight routes. So, I’m a huge fan and couldn’t recommend them more!

If you’re a frequent flier, consider getting their premium version. It costs $49 per year, but it will easily save you hundreds (or thousands) of dollars if you fly just 1-2 times. I recommend signing up for the free trial (which you can cancel at any time) to test it out for yourself. And if you like it, use my coupon code JON20 to save 20%!
