A ground stop for flights arriving at Denver International Airport (DIA) was lifted on Saturday afternoon, August 15, 2026, following severe thunderstorms that disrupted air traffic for several hours. The Federal Aviation Administration (FAA) had implemented the stop earlier in the day to hold arrivals due to storms affecting final approach paths.
Flight cancellations and delays by airline
As of 4:30 p.m. local time, FlightAware reported a total of 91 flight cancellations and 708 delays at DIA. The average delay for inbound flights was approximately two hours at that time. SkyWest Airlines recorded 38 canceled flights and 121 delays. United Airlines had 34 cancellations and 265
delayed flights. Southwest Airlines reported 14 cancellations alongside 211 delays, while Frontier Airlines reported five canceled flights and 49 delays.
Weather conditions and ongoing impact
Severe thunderstorms included damaging winds and large hail, prompting a severe thunderstorm watch for the Front Range region, including the Denver metro area, until 9 p.m., according to the National Weather Service. These storms caused the FAA to halt incoming flights temporarily due to safety concerns on final approach courses.
The thunderstorms continued to affect flight operations into the evening hours, extending delays beyond the lifting of the ground stop at 4 p.m. Travelers experienced widespread adjustments to schedules, with
hundreds of inbound flights affected primarily by severe weather hazards.
