Daring airport trend has travelers arriving at gate 15 minutes before takeoff

A viral trend has taken over social media showcasing a risky move made by many flight passengers.

Travelers are participating in the "airport theory" trend by arriving at their gates hst 15 minutes prior to departure.

A TikTok video shows a flyer setting a timer for 15 minutes as the person walks toward security. 

After 13 minutes, the TikToker revealed a successful arrival at the gate in time to catch the flight.

The TikToker said security went quickly, but the person needed to take a bus to transfer to the gate.

"My flight is just now boarding so we made it," the user said, adding that the boarding process had been delayed.

The user ended the video with a shot of the gate monitor that read "flight closed," meaning no more passengers were allowed to board - and the traveler missed the flight.

The user concluded, "Don't do it."

Fox News Digital reached out to TikTok users who appear to be participating in the travel trend.

Gary Leff, a Texas-based travel industry expert and author of the blog "View From the Wing," told Fox News Digital that people tend to show up at the airport too early. 

"The advice for when they need to arrive is too conservative. But 'airport theory' suggesting showing up 15 minutes in advance of departure is cutting it way too close," Leff said.

Leff said there are many things to be factored in with airport arrival, such as access to expedited security like PreCheck or CLEAR and the number of bags being checked.

"It all comes down to knowing how long the different pieces of the journey are likely to take, how much buffer your planning gives you, and just how bad it would be if you suffer a two-standard deviation event along the way," Leff said.
