The FAA issued the ground stop at DIA at 7 a.m. for “low ceilings,” which refers to the lowest level of cloud cover, according to the agency’s website. The ground stop lasted through 8:15 a.m. Thursday, but delays and traffic control programs continued.
As of 6:30 p.m., 1,005 flights had been delayed at DIA and 11 had been canceled, according to flight tracking software FlightAware.
Flights are delayed by more than two hours on average because of thunderstorms, FAA officials said.
