Airlines have begun issuing travel alerts and offering free changes or refunds, ahead of an expected snowstorm in the south and northeast this Friday.
The National Weather Service has posted a blizzard alert for Maryland, Washington, Virginia, West Virginia and Arkansas.
Snow in Kentucky and Tennessee has already caused the closure of some schools and resulted in at least one traffic related death.
American Airlines will ease its change fee policy for travel on flights departing January 21-24 through dozens of airports from New York to North Carolina.
These include Boston Logan, New York area airports, Rhode Island, Philadelphia, Tri-State and Yeager airports in West Virginia and Blue Grass Airport in Kentucky.
Delta Air Lines has advised customers that canceled or heavily delayed flights will be refunded and change fees are being waived for flights scheduled January 24-26.
Southwest Airlines, JetBlue, United Airlines and Frontier have all posted similar advisories and offered fee waivers to customers.
"Since we have advance notice of this weather event, we want to help out our customers by giving them the choice of making a change in their travel plans or requesting a refund," said Frontier spokesman Jim Faulkner.
