As of 11:59 p.m. EST, 921 flights within, into or out of the United States on Sunday have been cancelled, with an additional 7,722 delays, according to flight-tracking service FlightAware.
The National Weather Service said the weekend winter storm could make travel impossible in some places. Six to 12 inches of snow was expected from northeast New Jersey to Connecticut, with “impactful amounts of snow” Sunday into Monday in Boston and the interior of New England.
And it’s a busy travel weekend. Dec. 1 is likely to be American Airlines’ second-busiest day of the year, spokesman Ross Feinstein told USA TODAY.
From Nov. 30 through Dec. 3, American Airlines had more than 27,000 departures scheduled with more than 2.6 million customers.
Feinstein said the airline has issued a travel alert for more than 40 airports, including its New York and Philadelphia hubs.
