BLOOMINGTON, Minn — The holiday travel rush is in full swing at MSP Airport, but at the same time, officials are monitoring a winter storm making its way to Minnesota.

American Airlines, Delta, Sun Country and Southwest have issued travel waivers for fliers affected at MSP Airport. Under the waiver system travelers can either change your flight without getting charged, cancel your flight, or you can keep your flight and take your changes. Either way, travel experts strongly recommend you try to reschedule your flight ahead of the storm.

John Welbes, a spokesperson for the Metropolitan Airports Commission says the airport has about 100 plows ready to go. De-icing trucks are ready, as well. Once snow starts to fall, crews will work until the storm has passed.

"Crews will be out there making sure that the planes can take off if the weather allows and try to keep things running smoothly here," said Welbes.

He suggests you arrive to the airport two hours before your flight leaves, and three hours if you're flying internationally.
