A winter storm brewing in the northeast is set to upend weekend travel plans, with more than 5,600 U.S. flights canceled between Friday and Sunday.
The powerful nor'easter is expected to rip through the Mid-Atlantic and Northeast starting Friday night. Airlines canceled more than 1,450 Friday flights within, into, or out of the United States and delayed over 5,650, according to flight-tracking website FlightAware.
The storm has affected even more Saturday flights, with more than 3,500 U.S. flights canceled as of 7:30 a.m. ET. Affected airlines include JetBlue Airways, American Airlines, Delta Air Lines, United Airlines and Southwest Airlines. Hundreds of Sunday flights have already been canceled as well.
Travelers should check their flight status before heading to the airport and look into whether their flight is covered by travel waivers that will allow them to rebook without additional charges.
"The vast majority of impacted flights have been canceled in advance so we could proactively notify and accommodate our customers and avoid last-minute disruptions at the airport," American Airlines spokesperson Curtis Blessing told USA TODAY in an emailed statement. "We apologize to our customers whose travel plans may be affected, and want to thank our team who are working tirelessly to help us safely care for our customers."
Delta suspended operations at LaGuardia, John F. Kennedy, Newark Liberty and Boston Logan airports Saturday through Sunday morning but expects to restart operations Sunday afternoon, "depending on conditions," according to a statement from spokesperson Morgan Durrant.
FLIGHT DELAYED OR CANCELED?: These are your rights and what the airline owes you
What happens if my flight is canceled due to weather?
Airlines have been rolling out weather waivers that allow affected passengers to change their flight without penalty.
