DENVER (CBS4) – Everyone wants things to go smoothly for travelers on busy holiday travel days, but when things go wrong it’s nice to have understanding passengers.

Heather Kinder and her family were among the dozens of Frontier Airlines passengers whose flights were canceled Sunday due to crew scheduling problems after a bout of bad weather Saturday that held up some planes Saturday night and Sunday morning.

“Our flight was canceled to Little Rock today, so we are here until the 25th, so we’ll be spending our Christmas in Denver,” Kinder said. “We’re going to try to make the best of it — grin and bear it.”

Kinder said she and her family will be staying at a hotel in Denver instead of being in Arkansas. A Frontier spokesman told her the reason for the cancelation was flight crew issues. Kinder admitted “I don’t know what that means.”

Approximately 150,000 were expected to pass through Denver International Airport on Sunday.

In the afternoon there were just a handful of short delays at DIA, but not any more for Frontier than any other airline.

Frontier told CBS4 they are doing their best to accomodate passengers.

On Sunday afternoon the Pikes Peak parking lot and the east and west economy lots were full but there was still space in the other lots.
