Is it cheaper to buy a plane ticket from SAT to Houston Airport last minute?
Booking your trip from San Antonio Airport to IAH at the last minute could save you a tidy sum if you luck out and find a real steal. However, tickets don't usually get cheaper closer to the departure date. If you hold out, flights could also be booked out or the best seats taken (we hope you like the middle seat!). If you want to be on the safe side, book well ahead of your departure date. In fact, some of the best deals are available on Expedia up to a year in advance. If your favorite airline hasn't released tickets yet, check back regularly as deals are updated on Expedia constantly.

With an on-time flight record of 68%, United Airlines is the carrier most likely to fly you from San Antonio Intl. Airport (SAT) to George Bush Intercontinental Airport (IAH) on schedule. Flight delays aren't just an annoyance — they can also lead you to missing a connection that upends your entire trip. Stay updated about delays by looking up your flight status through the free Expedia App before you even reach the airport. If you're already at your gate and your plans will be significantly impacted, head to your airline's customer service desk to work out your next move.
What airports do you fly into for Houston from San Antonio?
From San Antonio, you can travel to Houston via George Bush Intercontinental Airport (IAH), William P. Hobby Airport (HOU) and Ellington Field Airport (EFD). Do some research into which hub is right for you before making your decision. If you pick George Bush Intercontinental Airport (IAH), it's roughly 26 kilometers north of downtown. Use the money you save when booking your ticket with Expedia to experience the city's well-known sights, such as Toyota Center and Minute Maid Park.

Between 12:00 PM - 1:00 PM is the busiest time for United Airlines flights making their way from San Antonio Intl. Airport (SAT) to George Bush Intercontinental Airport (IAH). Our suggestion? Book a trip that departs in the morning. With air traffic yet to build up around airports, your chances of boarding a delay-free flight are higher.
Can I change the date of my flight from San Antonio Intl. Airport (SAT) to Houston Airport?
Quickly make changes to your SAT to Houston Airport trip through the Expedia Trips portal. But before you make any adjustments, check the conditions in your itinerary to see what the carrier will let you do and if change fees apply. Some airlines have a change fee per person, on top of any difference in fares. But if you booked in the last 24 hours, you may be able to cancel for free and book new flights. You can also head to our Customer Service portal for more useful advice and to chat with our Virtual Agent.
