A winter storm moving across the country caused airlines to cancel and delay flights in more than two dozen cities.

U.S. Airways canceled 150 flights, and more were delayed.

Jacqueline Rothschuh-Krejci and her husband were stuck at Charlotte-Douglas Airport on a layover from Fort Lauderdale to Cleveland.

"We've been canceled twice," she said. "I think this is going to be the third cancellation."

They were trying to get to Cleveland for her mother-in-law's wake.

"We're still here," Rothschuh-Krejci said. "And our feet hurt and we're hungry."

Earlier in the day, there were long lines and crowds from the post-Christmas rush as people discovered their flights were delayed or canceled.

U.S. Airways announced a travel advisory, saying a winter storm would affect flights in and out of more than 20 cities, including seven cities in upstate and Western New York, five cities in Ohio and four cities in Pennsylvania.

U.S. Airways officials said in most cases, people can change their trips online, adding that the airline is waiving its regular $150 domestic change fee.

But travelers need to meet specific conditions to get home without shelling out more money.

Travelers need to keep the same departure and arrival cities and fly by Jan. 1.

They may have to pay if that isn't the case or if there's a difference in the fare cost.

Eyewitness News asked U.S. Airways officials for specifics but they said it all depends on what each traveler is doing. They said travelers should talk to a reservation agent if they have questions.

Rachel Smith, who was trying to get to Columbus, said she was getting mixed signals from the airline, starting with a call this morning that her flight would be delayed.

"Then I got a call saying it was canceled," she said. "Then I got a call two minutes later saying it was earlier than my originally schedule flight time. So now I just need to wait in line and see what's going on."

U.S. Airways spokesmen said the travel advisory lasts through the end of Thursday.

They said you should call U.S. Airways directly if part of your trip is on another airline or if you can't change your trip online.
