Why HOU gets delayed
Hobby is Houston's Southwest airport, and like Love Field and Midway its delays build through the day: 92% of departures left on time before 9 AM in BTS data and 58% after 9 PM. Half of all delay minutes came from late-arriving aircraft.
The FAA ran 40 programs for HOU in the 12 months to October 2026. Thunderstorms caused about half, and controller staffing 23%, mostly in a cluster of long programs between late October and mid-November 2025, during the federal government shutdown, including a 10 h 51 min program on November 7.
