NEW YORK (CNNMoney) — A small piece of good news if your Thanksgiving air travel has been thrown into turmoil by the winter storm: Several major airlines are letting customers change reservations without paying fees.
There are caveats, of course. But the savings could be considerable, since change fees can range from $100 to $300 per flight.
If you’re flying on Delta (DAL, Fortune 500), the airline is offering a one-time ticket change, without a fee, to Thanksgiving travelers to and from New York City, Washington, D.C., Boston, Baltimore and other airports in the East.
Delta also said travelers are entitled to refunds if their flights are canceled or “significantly delayed.”

US Airways (LCC, Fortune 500) is also relaxing its change-fee policies for travelers scheduled to fly during the days leading up to Thanksgiving, so long as the airports and the fares remain the same.
JetBlue (JBLU, Fortune 500) and American Airlines of AMR Corp. (AAMRQ,Fortune 500) waived their change fees for customers who were scheduled to fly to or from Dallas/Fort Worth on Nov. 24 or 25, after Texas got pummeled by an ice storm.
United, of United Continental Holdings (UAL, Fortune 500), is waiving fees for some passengers traveling to or from Cleveland, Washington-Dulles or Newark, N.J.
The storm is expected to hit the East Coast on Wednesday.
