With air travel during the holidays a notorious nightmare, one airlines decided to lift their passengers' spirits by surprising them with an unexpected Christmas present.

With the help of over 150 volunteers, Canadian low-cost carrier WestJet spent the past four months putting together this year's "Christmas Miracle" stunt, uploading the result to YouTube over the weekend.

Here's the gist of it:

Passengers heading to Calgary from Toronto and Hamilton were invited to share their Christmas wish with a real-live Santa Claus before boarding their planes.

WestJet then sent its "elves" to various stores around Calgary to pick up the items the passengers asked for.

Finally, upon arriving at the baggage carousel, passengers were greeted with individual gift boxes containing their custom "Christmas miracle."

Of course, the stunt was equal parts naughty and nice: While customers certainly got what they asked for, some would probably have asked for other things had they known they were actually getting them.
