The modern, big-city energy of Houston is a contrast with the more chilled-out, historical focus of San Antonio. Traveling from Houston to San Antonio is quick and easy. By air, you’ll travel the roughly 200 miles between the cities in under an hour’s flight time.

For a trip this short, direct is the only way to go. United offers 78 non-stop flights between Houston’s George Bush Intercontinental Airport (IHA) and San Antonio International (SAT) every week. Southwest also has a non-stop route, with 30 weekly flights back and forth.

Making your way to Houston’s Airports

Houston’s largest and busiest airport is the George Bush Intercontinental Airport(IHA). Depending on traffic, it will take you about an hour’s driving time to get from downtown to the airport. If you want to take public transportation, METRO’s public bus route 102 connects to IHA and tickets are just $1.25. The airport consists of 5 large terminals. You can travel between terminals without having to leave the secure area. The TerminaLink train connects terminals B through E, and a bus service provides also transport between Terminals A, B and C. Every terminal also offers WiFi and a relief area for traveling pets.

If you’re flying with Southwest, you’ll need to get to William P. Hobby Airport(HOU). It’s a single-terminal airport, easy and convenient, especially for short trips. HOU is just 10 miles outside the city and the drive should take you about 20 minutes. You can also catch the METRO public bus route 88. The fare is $1.25. If you’re driving, the trip is about 20 minutes long. You’ll find Hobby’s pet relief area on the east side of the baggage claim area and just north of the passenger pickup area. WiFi is available throughout the terminal.

Arriving in San Antonio

The historical heart of the city is The Alamo, revered around the state as the cradle of liberty for all Texans. It’s San Antonio’s biggest tourist draw, and absolutely worth a visit. History buffs in general will find a lot to love here, with restored missions and beautiful old churches like the Cathedral of San Fernando sharing space with the city’s contemporary architecture.

Of course, you can’t mention San Antonio without talking about the city’s beautifully restored River Walk. A story below street level, it provides a shady escape from the Texas heat, offering miles of dining, shopping, and strolling enjoyment.
