American Airlines and Southwest Airlines are canceling more flights as the East Coast recovers from the massive weekend winter storm.
Officials at Fort Worth-based American Airlines updated their travel policy to include 42 airports, including hubs in Charlotte, Washington D.C., New York City and Philadelphia.
Customers whose travel plans are affected by the storm can rebook without penalty.
"Email notifications have been sent to all of our impacted customers, informing them of the waiver. They will also receive another communication if their flight is cancelled," the airline said in a statement Thursday.
Customers whose flights are cancelled can request a refund or reschedule their travel on aa.com by retrieving their reservation. Customers may also contact American Airlines reservations at 1-800-433-7300 in the U.S. or Canada. Customers calling from outside the U.S. or Canada should check aa.com for our worldwide reservation phone numbers.
Across the country, airlines canceled more than 6,000 flights over the weekend, as the storm dumped more than two feet of snow in some locations.
Dallas-based Southwest Airlines said service at 20 airports may be impacted by delays or cancellations.
