(NEW YORK) — It’s the unofficial kick-off to the summer travel season, and automobile club AAA predicts 2.5 million people will take to the skies over Memorial Day weekend alone.
That’s a decrease from last year, but don’t think you’re going to breeze through the check-in line and airport security, especially if you’re flying out of one of the airports below.
FourSquare has analyzed check-in data to find out which of our nation’s airports will be the busiest over the upcoming holiday weekend. Here are the top 10 busiest airports for Memorial Day weekend:
1. Hartsfield-Jackson Atlanta International Airport
The world’s busiest passenger airport won’t get a break this Memorial Day weekend. As a Delta hub, there’s a good chance you’ll be flying through ATL if you’re on a Delta flight.
2. San Francisco International Airport
SFO comes in at number two this Memorial Day weekend. Morning flights are frequently delayed due to fog, so book a mid- or late-morning flight instead.
3. Chicago O’Hare International Airport
It’s coming in at number three, but not because it’s a major hub. Bad weather in Chicago can ground flights all over the country. Hopefully the weather will cooperate this Memorial Day weekend.
4. John F. Kennedy International Airport
It’ll be the busiest of the three major New York City-area airports. Flying out of LaGuardia or Newark? You’re not off the hook, they’re just a little further down the list.
5. McCarran International Airport
Bet on crowds at the Las Vegas airport, coming in at number five on Foursquare’s list. It’s also the number one summer destination on Orbitz’s top 10 list of summer destinations.
6. LaGuardia Airport
Over 24 million people flew out of New York’s LaGuardia Airport last year. It’s just eight miles from Manhattan and the favorite area airport of many New Yorkers.
7. Denver International Airport
The best part of Denver International Airport is the volunteer airport greeters that are there to help with all your airport questions. Look for the white cowboy hats.
8. Boston Logan International Airport
If Boston’s too crowded or too expensive this Memorial Day weekend, try the nearby airport in Providence, R.I. It’s usually less crowded and sometimes cheaper.
9. Seattle-Tacoma International Airport
The airport’s website claims it’s the 17th-busiest overall, but this Memorial Day weekend it’s expected to come in at number nine.
10. Newark Liberty International Airport
Rounding out the top 10 is EWR. Even though it’s in New Jersey, it’s a popular choice for New Yorkers as well, especially for international flights.
