Search FlightsTraveling from the bustling energy of Houston to the live music capital of the world in Austin has never been easier or more efficient than with a quick direct flight between IAH and AUS. While many locals choose the drive along the often-congested I-10 and Highway 71 corridor, opting for a flight allows business professionals and leisure travelers alike to bypass the unpredictable Central Texas traffic and arrive refreshed in under an hour. This short hop connects the state's largest economic hub with its vibrant political and cultural heart, offering unparalleled convenience for those looking to maximize their time in the Lone Star State, whether they are attending a board meeting or a music festival.
Travel Tips
First, consider using the United Airlines hub at IAH for the most frequent daily departures, which provides significant flexibility for last-minute schedule changes or business delays. Second, since this is an incredibly short flight—often less than 45 minutes in the air—don't expect a full meal service; instead, pack a light snack or grab a coffee at the terminal before boarding. Third, download the mobile apps for both Houston and Austin airports to monitor real-time security wait times, as both IAH and AUS can experience sudden surges during peak business travel hours on Monday mornings. Finally, if you are traveling with only a carry-on, you can often breeze through the Austin airport upon arrival, as the terminal layout is relatively compact and efficient compared to Houston.
Airport Information
Houston (IAH)
George Bush Intercontinental Airport (IAH) serves as a major international gateway and a primary hub for United Airlines, located approximately 23 miles north of downtown Houston. As one of the busiest airports in the United States, it features five expansive terminals connected by an underground manual train and an above-ground Skyway. Travelers can enjoy a wide array of amenities, including high-end dining options that showcase Texas's famous Tex-Mex and barbecue heritage, alongside numerous lounges and retail shops that cater to global travelers.
Austin (AUS)
Austin-Bergstrom International Airport (AUS) is located just southeast of downtown Austin and perfectly captures the city's unique spirit through its live music stages and local food vendors. Since opening on the site of the former Bergstrom Air Force Base, it has become one of the fastest-growing airports in the country, serving as a vital link for the tech industry and international tourists. The terminal features local favorites like Salt Lick BBQ and Amy’s Ice Creams, ensuring your Texas experience begins the moment you step off the plane.
Seasonal Pricing Patterns
Flight prices between Houston and Austin remain relatively stable throughout the year due to the high volume of business travelers, but you will notice significant spikes during major local events. Specifically, demand and pricing soar during the South by Southwest (SXSW) festival in March and the Austin City Limits (ACL) music festival in October. For the cheapest fares, look for mid-week departures in late January or August, when the intense Texas heat and lack of major conventions typically lead to lower occupancy on these short-haul regional routes.
