As a powerful winter storm continued to rage over the weekend with a nor'easter forming off the New England coast and the Midwest expecting more heavy snow, airlines are offering waivers to their customers.
As of 11:59 p.m. EST, 921 flights within, into or out of the United States on Sunday have been canceled, 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.

Airlines offering waivers
The waivers that airlines, including American, are issuing give travelers who have booked flights on specific dates heading to and from certain cities the option to change or cancel their flights for no fee during the storms.
Here's a look what some airlines are offering:
- JetBlue is offering a "Winter Storm Ezekiel Waiver."
- American Airlines has a list of airports that customers traveling to, through or from can change their trip at no cost because of winter weather.
- United Airlines is offering travel waivers to passengers going through airports in New England or San Francisco because of the weather.
- Delta Air Lines is offering waivers for travelers headed to or from the Midwest, Upper Midwest or Northeast areas of the country.
- Southwest Airlines has travel advisories listed for the Northeast and Minneapolis/St. Paul. Travelers going through any of the listed airports may rebook in the same class or be put on standby for another flight within 14 days of the original ticket with original city pairings.
