Kleenex alert: the following video will fill you with holiday warmness and may invoke a tear or two.

The folks at WestJet are giving back to customers during the holiday season.

In the video entitled "WestJet Christmas Miracle," WestJet did a pretty cool thing.

The Canadian carrier, with the help of Santa Claus, nonchalantly asked passengers at the Toronto and Hamilton International Airports what they wanted for Christmas this year.

Then, more than 150 WestJet employees, or elves, went shopping for the desired gifts. By the time passengers landed in Calgary, presents had been set up to greet them at the airport.

The spectacle, captured by hidden cameras, was presented on YouTube and themed after the poem "The Night Before Christmas".

WestJet vice president of communications and community relations Richard Bartrem explains how the event came together in this video.

WestJet even unveiled a bloopers video featuring Santa Claus.

Last year, WestJet created a flash mob centered around Christmas. The video was so popular—receiving more than 500,000 views—that the airline decided to donate flights to a family in need through its community investment program.

This year, WestJet said it would donate flights if the "WestJet Christmas Miracle" video received more than 200,000 views. It has already received more than 1.5 million views on YouTube as of this writing.

WestJet is making sure it rewards customers for their loyal service, and customers appear to be returning the favor by adding to the carrier's publicity and popularity.

If that doesn't exemplify the spirit of giving during the holidays, I don't know what does.
