Final boarding call…

If you’re lucky, you might be able to fly through security and be blessed with a nice gate attendant that will let you sneak onto the plane after the final boarding call announcement has been made. But sometimes things don’t work out and you’re left watching your plane back up from the airport without you on it. FinanceBuzz analyzed data from the 45 busiest airports in the United States to find the ones that are least forgiving when it comes to you running late for your flight. They analyzed a number of different factors—including average TSA wait time, number of departing passengers, on-time departure percentage, the number of gates, and the terminal square footage—then gave each airport and rating to see how they ranked in time it takes to get from the entrance of the airport to your gate. If you always tend to cut it a little too close when flying, you want to avoid these ten airports. A lot of the airports on this list also make the list of the busiest airports in the world.

#10: John F. Kennedy International Airport (JFK)

At JFK there’s a 75 percent chance that you’ll get stuck in the security line for more than 15 minutes, and on average the wait time is about 25:08 minutes. Even though this airport comes in at number ten on the list, it’s still a bad one to book through if you always run late. This is the most reliable airport in the United States.

#9: Detroit Metro Airport (DTW)

Detroit Metro has the shortest TSA wait time of 24:08 minutes, and about 20 percent of the time that wait is shorter than 15 minutes. But, this airport has a high average percentage of on-time flights, so even if you fly through security, your plane could already be pulling away from the jet bridge.

#1: Newark Liberty International Airport (EWR)

And the worst airport to travel out of if you’re running late is Newark International Airport in Newark, New Jersey. The average TSA wait time was the longest at 33:53 minutes.
