Several major U.S. airlines announced Friday that they are offering waivers to travelers who are impacted by the historic winter storm this weekend that is projected to affect more than two dozen states.

States have already begun preparing for the massive snow storm, which could impact over 180 million Americans in the South, Midwest and Northeast. The storm is expected to impact some states beginning Friday and ending Monday.

Weather experts are encouraging Americans to stay home this weekend because the mix of freezing rain, sleet and snow could make travel dangerous and result in power outages, according to Fox Business.

Delta Air Lines began canceling some of its flights on Thursday at airports in Arkansas, Louisiana, Oklahoma, Tennessee and Texas, as a precaution ahead of the weekend. The travelers were rebooked to the next best itinerary and those whose flights have not been impacted so far but will be this weekend will have flexibility to change their travel with no fees.

Southwest Airlines said it will be offering customers the flexibility to rebook their flights that are impacted by the storm or be placed on a standby flight within a two-week window.

American Airlines and United Airlines said they are offering similar waivers for travelers to rebook their flights in major hubs like Dallas and Charlotte, North Carolina. 

JetBlue said it will issue a waiver for travelers in the Northeast, including New York and Boston-area airports, and will also waive cancel fees for travelers flying to and from 11 airports.

Budget airline Frontier said it will also help accommodate travelers impacted by the weather this weekend, by allowing travelers to request a refund if flights are canceled or delayed for more than three hours for domestic flights or six hours for international flights. 

Americans who still expect to travel this weekend are encouraged to monitor their flight status closely and use mobile apps and airline websites to rebook their flights in case of cancellations.
