For when you don’t feel like doing the drive.
United has round-trip flights from Houston (IAH) to San Antonio (SAT) for $97, NONSTOP. Flights November to February. Departures on Monday, Tuesday, Wednesday, Thursday, and Saturday. Extended Weekends available. Origin/Destination reversible.
Note: United “Basic Economy” fares do not include a free carry-on bag. Only a personal item (like a small laptop bag) is free. Seats are randomly assigned for free prior to boarding. If you have the United MileagePlus credit-card, use the “free checked bag” perk.
Note: The personal item size on United flights is smaller (9-in/10-in/17-in) than Frontier or Spirit (8-in/14-in/18-in).
