Talk about killing a spring break buzz.

A new report highlights airports around the U.S. that are notorious for delays and other bad service for the months of March and April.

Perhaps not so surprisingly, several popular spring-break destinations like South Florida and Las Vegas earned spots atop the 10 worst in the nation, according to Department of Transportation data analyzed by aGamble.

First and worst is Fort Lauderdale-Hollywood International Airport, with a reported 39.5% rate of delays during the two-month time span. On top of that, 4.6% of its flights get canceled.

At nearby Miami International, the sixth worst on the list, about 30% of flights succumb to delays around those weeks, too.

Travelers heading to Las Vegas’ Harry Reid International are also out of luck as it’s the second worst in the U.S. for spring break — with just two-thirds of flights departing on time from there.

In addition, the Nevada transit hub saw 465 flights canceled in both March and April.

Those in Disney World’s home city likely don’t find Orlando International to be the happiest place on Earth: the third-worst springtime airport sees a third of flights delayed and 436 canceled.

Things aren’t much better in the tri-state area, either. Newark-Liberty Airport was ranked seventh with about 26% of its flights delayed, and JFK ranked 10th with 25% stalled departures.
