A DFW Airport spokesperson says 84 percent of flights at the airport are with American Airlines.

Many passengers traveled with families, including small children.

Herget says she and her fiancee’s flight Thursday morning was cancelled – and all flights online were cancelled or booked already.

“She was on hold with customer service for an hour. They tried to get us into Chicago for a layover and into Minneapolis. But that flight cancelled when they were on the phone. They told us everything is canceled,” says Herget.

The Littleton family from Plano were headed to Walt Disney World but their flight was cancelled.

The family has spent hours trying to get their luggage back.
