‘Home Alone 2’ nailed holiday travel chaos, but flight rules make movie's plot less plausible today

The parents' alarm clock never rings, bags and coats spill across the floor, and the family barrels out the door to catch a flight to Florida. There, the McCallisters must dodge fellow holiday travelers and luggage as they sprint to their gate while final boarding calls echo overhead. Amid the mayhem, 10-year-old Kevin accidentally boards the wrong plane and finds himself alone in New York City just days before Christmas.
