Following the warning of a “nor’easter,” which is expected to hit the Mid-Atlantic and Northeast shores on Friday, many airlines are waiving change and cancel fees for passengers.

It’s no surprise: with expected winds of at least 40 mph, inland snow, flooding and heavy rain, potential flights are destined to be grounded. Though each airline has different qualifications for rescheduling, most passengers will not be penalized for changing their schedules.

JetBlue announced the company will be waiving fees for those traveling March 2 and March 3 from airports in New York, Connecticut, Rhode Island and Massachusetts. Original travel must have been booked on or before February 28, and the rebooked travel must be no later than March 6. American Airlines is following JetBlue’s lead, though the original travel must have been booked by February 27.

Southwest will be waiving fees for flights scheduled on Friday or Saturday from 12 airports, including LaGuardia Airport (LGA), Philadelphia International Airport (PHL) and Long Island MacArthur Airport (ISP). Those with cancelled flights may request a refund for their ticket.

If you’re flying Delta from T.F. Green Airport (PVD), John F. Kennedy International Airport (JFK), Boston Logan International Airport (BOS) or another of their nine listed airports, you may reschedule by March 6 so long as you had planned to travel on or prior to February 28.
