Winter storm cancels 30% of all US flights: What to know

Travel delays are all but certain for passengers at some of the nation’s busiest airports as a massive winter storm brings crippling ice, snow and bitter temperatures to 180 million people. 

If you haven’t changed your travel plans yet, you may want to do so before your scheduled flight time. 

Flight cancellations

By the numbers:

More than 13,500 flights have been canceled across the U.S. since Saturday, according to flight-tracking site FlightAware. About 9,600 of those were scheduled for Sunday. Aviation analytics company Cirium says its data shows that Sunday will be the highest cancellation event since the pandemic, with over 29% of all U.S. departing flights axed.

Significant disruptions were also expected at major airport hubs in Dallas-Fort Worth, Charlotte, Philadelphia and Atlanta, home to the nation’s busiest airport, as well as New York’s John F. Kennedy International Airport and LaGuardia Airport.

American Airlines had canceled over 1,400 flights for Sunday, according to FlightAware. Delta Air Lines and Southwest Airlines each reported about 1,000 cancellations for the day, while United Airlines had more than 800. JetBlue had more than 560 canceled flights, accounting for roughly 70% of its schedule for the day.

What if my flight is canceled?

Big picture view:

If your flight is canceled, airlines will book you on another flight, but if multiple flights are canceled because of weather it may be a problem. Sometimes, they’ll partner with competing airlines to offer seats on other flights when the airline you’re flying with can’t accommodate. 

According to the U.S. Department of Transportation, you are entitled to a refund if your flight is cancelled or significantly delayed – regardless of the reason – but only if you choose not to travel or accept travel credits, vouchers or other forms of compensation offered by the airline.

If you want to rebook your flight, do it as soon as you learn your flight is delayed or canceled. Try re-booking it quickly online, with the app or at the kiosk. If the airline’s phone number is backlogged, try calling through the international number – according to The Points Guy. If that doesn’t work, then try a ticketing agent. Speed is your friend here.
