About this route
Houston to Austin flights
Houston to Austin is one of the shortest commercial flights in Texas — under an hour in the air. It competes directly with the 2.5-hour drive on US-290, but for business travelers and connecting passengers at IAH, flying wins.
United operates from IAH while Southwest flies from Hobby (HOU). Despite the short distance, this is a high-frequency route due to demand from the tech industry in Austin and the energy sector in Houston. Same timezone keeps coordination simple.
