If you're flying anywhere this winter, you might want to avoid the airports in Chicago, Fort Lauderdale and Newark. Travel planning and data site Hopper analyzed data from the Bureau of Transportation Statistics and its own flight search numbers to determine the 20 busiest airports most likely to have delays between this December and March. 

Chicago's O'Hare International Airport came out on top, with a whopping 42 percent of all flights facing delays. Florida's Fort Lauderdale-Hollywood International Airport came in second, with 38 percent of flights delayed. Newark Liberty International Airport and Denver International Airport tied for third place; both had 37 percent of flights delayed.

Three other Florida airports made the top 10. Because the Sunshine State is a popular winter destination, it's often affected by winter storm delays from other cities, according to Hopper. But warm weather seekers should take heart: Hawaii is your best bet for uneventful winter travel. The Honolulu airport only saw 14 percent of flights with delays.
