Every year, some unlucky Americans end up stranded at U.S. airports trying to get home for Thanksgiving. But your risk of getting stuck at the airport for hours on end varies depending on where you’re flying. Using five years of data from the U.S. Bureau of Transportation Statistics, Elite Fixtures collected statistics on the worst airports to travel through around the Thanksgiving holiday, a time when airports are traditionally at their busiest.

The results show that delays aren't necessarily tied to the airports where the weather tends to be worst or those that see the most passengers. What airline you are flying, whether you’re on a regional flight, and the route you’re traveling can all affect your likelihood of getting stuck, and so the percentage of short-haul flights or the number of, say, Delta flights out of a certain airport might affect its overall score negatively. Still, you might want to avoid airports like Chicago’s Midway or the Oakland airport. Good luck with Houston or Dallas, too.
