Blizzard Nemo Tracker: Over 1,000 Flight Cancellations Reported As Killer Storm Bears Down On Northeast

As Winter Storm Nemo barrels into the Northeast, travelers should be wary: the storm has already caused over 1,000 flight cancellations.

Accuweather meteorologist Alex Sosnowski says that "enough snow will fall to cause travel problems."

"Low cloud ceilings and increasing winds during Friday may lead to building flight delays and cancellations, even if snow were to stay away from the several major airports in the New York City area."

Sosnowski cautions that in the north, "blowing and drifting snow, blocked roads and other travel problems are likely to linger into much of the weekend." More than 950 flights in and out of the United States are canceled, while another 250 on Saturday.

Here's what the major airlines are doing:

US Airways has waved fees for passengers at 26 airports from Montreal to Scranton, Pa. Friday and Saturday.

American Airlines has issued an advisory 14 airports from Quebec City to New York City and waived change-fees.

United has issued an advisory for 11 New York, New Jersey, and New England (triple kill!) airports on Friday and Saturday. Fees for same-day flight changes have been waived, so long as the new flight departs within 24 hours of the originally scheduled time.

Delta is offering a one-time change for those flying into 24 Northeast or Canadian airports on Friday or Saturday.

Southwest has issued travel advisories, though you'll need to enter your airport and flight # on their website for specific information regarding delays, cancellations, and waived charges.

Jetblue will allow passengers traveling in or out of 12 New York to Maine airports on Friday or Saturday to rebook their flights, and waived all charge and cancel fees.

Air Canada will allow passengers entering in and out of Toronto Thursday will be able to change their flights penalty-free.
