(USA Today)-- Airlines waived change fees at airports from Texas to Pennsylvania as delays and cancellations snarled flights as a winter storm trekked over a large swath of the United States on Friday (Dec. 6).
The biggest disruption came at Dallas/Fort Worth (DFW), where American Airlines and regional affiliate American Eagle grounded all departures for a large part of the day because of wintry weather. All told, American and American Eagle grounded more than 1,400 flights.
"While we have very limited operations today, flights are leaving DFW as airport conditions improve," AA said in a statement issued at about 4:45 p.m. ET. "We have added some extra flights from other hub airports to accommodate customers affected by the cancellations. Our employees are working hard to enable the airline to return to more of a normal operation on Saturday."

FLIGHT TRACKER: Is your flight on time?
Nationwide, flight-tracking company FlightStats reports that more than 2,100 flights were canceled as the messy winter storm moved east out of the south-central USA. About two-thirds of that total came from American's cancellations at DFW, where the company operates its biggest hub.

But that wasn't the only problem. In addition to the cancellation, another 4,200 had been delayed nationwide as of 4:40 p.m. ET, according to FlightStats. Chicago O'Hare, Denver, Philadelphia, Atlanta and the New York City-area airports were among those with most delayed flights.
The Federal Aviation Administration's flight-delay map showed flights arriving to Philadelphia, Newark Liberty and New York LaGuardia were being delayed by an average of 45 to 2 hours.
