Strong winds and snow are grounding flights in Chicago and Minneapolis. Even if travelers can make it out of Sioux Falls, many aren't sure just how far they'll get.
"We got a stop in Minneapolis and I understand that one is delayed out of Minneapolis, but we'll see when we get there," traveler Joe Vig said.
It's the same story for passenger after passenger, delays and cancellations are causing headaches.
Some travelers say they are arriving extra early so they have time to reroute their travel plans
"I say we'll spend a little time in the airport for a while, I imagine," traveler Rick Borkhuis said.
Borkhuis arrived more than five hours before his flight. He, like many travelers, wanted to be around in case of a flight change.
"We're just happy we don't have to rearrange any flights or that any of our flights have been canceled. This is tremendous," traveler Brad Spevak said.
Spevak and his wife, Margie, are fortunate. They say they are flying to Orlando without a problem.
"We can't wait to get there but hopefully the other folks don't have to sit in an airport too much time before they can fly out," Margie Spevak said.
For those stuck in the airport, one frequent flier says there's not much you can do except wait until things get cleared up and planes start taking off again.
"You have to roll with the punches, take a deep breath and try to be patient. Sometimes it's not very easy but there isn't much else we can do. The airlines own the airplanes so it's up to them," Vig said.
