United Airlines passengers in Houston were offered flexible rebooking after the FAA imposed a ground stop at George Bush Intercontinental Airport on 23 May, with storms and flood risks in the Houston area sending delays through one of the carrier's biggest hubs and into the wider US network. The disruption left United with the highest number of cancellations among US airlines that day and briefly made Houston the world's most delayed departure airport.
