Updated flight rules impact realism of ‘Home Alone 2’ plot.

Panic ensues in the McCallister household as they rush to catch a flight to Florida, with 10-year-old Kevin accidentally boarding the wrong plane to New York City. In today’s age of tight airport security, experts say Kevin wouldn’t have been able to board the plane alone.

Despite the chaos, holiday travel remains popular, with millions expected to hit the roads and skies during the festive season.
