A day after scores of passengers experience long delays amid the first snowstorm of the season, Denver International Airport is working to return operations to normal.

There's no snow in Friday's forecast, although highs aren't expected to exceed 38 degrees. Crews are continuing to clean the airfield.

Thursday evening, DIA said on Twitter that United Airlines was experiencing delays due to deicing and vendor equipment issues. Travelers were urged to check their flight status.

Several people contacted 9NEWS about the delays. One said on Twitter that they'd been stuck on the plane for more than hour waiting to disembark. Another person said they've been on the ground at DIA for more than two hours waiting for gate.

According to flydenver.com, numerous United flights were either delayed or canceled.

Other airlines were also reporting delays but they were much shorter.
