ATLANTA (AP) — Delta Air Lines said Friday that it is letting customers whose flight plans may be affected by winter weather in five Midwest states this weekend make one-time changes to their travel schedules without having to pay fees.

The initiative applies to customers booked on Delta flights that take off, arrive or fly through Iowa, Minnesota, North Dakota, South Dakota and Wisconsin on Friday and Saturday.

Those passengers may rebook for travel before or after their original travel dates as long as they get their tickets by Saturday, the company said.

Travel for changed itineraries must begin by Monday and any changes to the flight's point of origin or destination may result in a higher fare.
