DENVER - Denver International Airport is expected to return to normal operations on Sunday.
On Saturday, DIA reported more than 600 cancellations as a winter storm barreled down on Colorado's mountains and plains.
Delays are also expected, and travelers are being reminded to check their flight status at flydenver.com or with their airline.
Frontier, United, Southwest airlines and U.S. Airways are waiving change fees for passengers traveling through cities expected to be affected by the storm.
Weather conditions on Saturday are expected to lead to the delay or cancellation of flights into and out of several airports in the Midwest and Mid-Atlantic regions.
DIA spokesman Heath Montgomery says travelers whose flights were not canceled can expect delays as crews deice airplanes.
DIA normally has an average of 1,700 flights per day, with slightly fewer on the weekend.
Meanwhile, Mindy Crane with the Colorado Department of Transportation says 340 snow plows have been deployed across the Front Range, including 75 in the Denver metro area. Another 30 plows are working the Interstate 70 corridor from just west of Denver to Vail.
