The FAA briefly halted departures Saturday at Houston’s Bush Intercontinental Airport as heavy rain and flooding risk swept across the city, and United Airlines ended the day with 27 canceled flights, the most of any U.S. carrier. The ground stop at Bush Airport was lifted at 5:45 p.m. ET, but the disruption had already spread across the schedule.
More than 61% of departing flights at Bush were delayed on Saturday, when the airport handled 388 total departures and 318 arriving flights were also hit by delays. United, which uses Bush as one of its major hubs, reached out to passengers with flexible rebooking after the disruptions and said affected travelers could change their plans without paying change fees or fare differences.
The airline’s travel alerts page was updated with a Houston thunderstorms section, underscoring how quickly the storm system rippled through its network. By Sunday, United still had 834 delays and 16 cancellations, while disruptions continued at other major hubs. The scale of the trouble pointed to more than a brief Houston slowdown; it became a broader operational problem that carried into the next day.
United’s rebooking offer was narrow. Tickets had to be on a United flight departing between May 21, 2026 and May 26, 2026, for the same cities and in the same cabin as the original trip, and the original ticket had to be purchased on or before May 21, 2026. That leaves passengers with a workable option, but only if their plans fit the airline’s exact terms.
The question now is not whether the storm caused the cancellations. It did. The question is how long the schedule at Bush and United’s other hubs takes to settle once weather, flooding risk and a crowded summer travel calendar collide.
