The family is on a flight to Colorado to spend Christmas with some relatives, and this is a trip that Danny has spent months planning -- but on the way to Colorado, a blizzard forces an emergency landing at an unfamiliar airport. The family is forced to spend Christmas in the baggage claim room, where everyone thinks Christmas is ruined this time around. Among the things that happen here are: Jesse's father Nick tries to get Jesse to kiss Becky under a mistletoe, D.J. is upset that the gifts that the family brought along on the flight with them are missing, and Michelle is afraid of Lionel, a man who made her cry on the airplane. Jesse, becoming ever so frustrated by everyone's sour attitudes, speaks to the people in the baggage claim room about the real meaning of Christmas, then Santa Claus shows up and shows the family where the missing gifts are, and it turns out that Lionel is Santa Claus.
