NASHVILLE, Tenn. (WKRN) — Winter weather has not only impacted travel in Middle Tennessee but it’s also canceled thousands of flights across the nation Friday.

According to Flight Aware, before 5 a.m., there were 4,177 flights canceled within, into, or out of the United States. The East Coast experienced a major winter storm, which caused major delays and cancellations at airports in New York, Washington D.C., and Boston.

Crews continued to clear runways after 6.3 inches of snow hit the Nashville International Airport (BNA), but dozens of flights had already been canceled for Friday. BNA announced 103 flights were canceled, along with 81 delays.

Thursday, BNA saw nearly double the number of cancellations when it came to outbound and inbound flights. At one point, the John C. Tune Airport runway was closed for a few hours for snow removal.

BNA officials said some of the runways are over one mile long, meaning it took crews multiple trips to clear each one – not including taxiways.
