Continuity mistake: Towards the end of the film and in the shot of the 747 as it turns to change course to Salt Lake City the company's name "Columbia" is printed on the aircraft's side on top of a large, white rectangle. After the aircraft comes to a stop on the tarmac the white rectangle is gone and the name is painted directly on its metallic fuselage.
Factual error: The 747 takes off from Washington D.C., while there's still some daylight, toward the west coast. Due to complications it's diverted to land in Salt Lake City. The Sun goes down and the plane is shown flying all night long. The Sun even comes back up before they get to Salt Lake. Really, how could it take that long for a jumbo jet to fly a measly couple of thousand miles?
