For those taking off today on a holiday or heading back home for Christmas, be warned today is the busiest travel day of the year at the Calgary International Airport.

Jody Moseley, spokesperson for the Calgary Airport Authority, says passengers should expect lineup delays.

She suggests people come a little earlier than they normally would.

Roughly 50,000 travellers are expected to go through the Calgary airport today.

There are no flight delays so far, but some have been cancelled.

Travellers are reminded to check the website before heading to the airport.

Cancelled flight forces Plan B

The freezing rain and snow in B.C. is causing some travel problems for Chris Moren and Taro Snell.

They found out today their flight to Vancouver was cancelled and there is not another flight until Saturday. The pair decided to rent a car and drive home for the holidays.

But there are number of things being offered at the airport to keep people entertained if they are waiting, such as carollers and volunteers wrapping Christmas presents. There is also the oxygen bar and spa available for stressed-out travellers waiting for a flight. 

Teena Dashin, who is heading home to Fort St. John, was able to catch up on some Christmas shopping while waiting for her flight. 

"Calgary is one of the better airports for that —​ there's lots of shops and good things to do."
