Airlines scramble after winter storm cancels and delays thousands of flights

A winter storm left many airlines scrambling to catch up after thousands of flights were canceled or delayed.

Travelers hoping to catch a flight somewhere in the U.S. likely experienced a delay or cancelation of some type on Monday, with over 5,000 cancelations and 18,000 delays on the books, according to reports.

Flight tracking website FlightAware.com reported 18,068 flight delays on Monday, with 7,143 of those delays being associated with flights within, into, or out of the U.S.

Southwest Airlines reported the largest number of cancelations of the day, with a total of 2,817 as of 7:30 p.m. The airline also reported the highest number of delays, at 723.

The delays are, for the most part, the result of extreme winter weather that swept across the U.S. when Winter Storm Elliot left behind a mess of snow, leaving some stranded on the roads, and many in their homes.

"Airports across the system have seen improved conditions which have allowed irregular operations recovery and a gradual return to normal operations," the release read. "A component of this recovery included repositioning aircraft and crews. While the build of the severe weather has passed, some cancelations subsisted through Monday afternoon due to damage to airport infrastructure, frozen equipment, and continued restrictions on some otherwise routine ground operations."
