A new TikTok trend called airport theory is telling travelers they can show up just 15 minutes before their flight and still make it on board.
The idea behind this trend is that people waste too much time waiting at the airport. Some TikTok users claim they have walked straight through security and onto their flight without any problems.
But what these TikTokers aren’t mentioning is that airlines often give away your seat if you’re not at the gate 15 minutes before departure.
Airlines also close the doors about 10 minutes before takeoff—so cutting it that close is extremely risky.
Some people have successfully boarded last-minute, but many have missed their flights completely. This has led to a big spike in online searches for “what to do if you miss your flight.”
TikTok Users Put “Airport Theory” to the Test
While many travelers are skeptical about showing up last-minute, some TikTokers have documented their experiences testing “airport theory”—with mixed results.
One user decided to try it at Atlanta Airport, the busiest airport in the world. In his video, he says:
“If airport theory works here, I think it’ll work anywhere.”
With no checked bag and a lucky break at TSA PreCheck, he made it to his gate in under 15 minutes. He admitted that security was busier than expected but still called it a win:
“Airport theory is looking good!”

Another TikToker arrived at security after boarding had already started and still managed to make it onto his flight with time to spare. After rushing through the airport, she celebrated her success:
“I was the first one to walk on the plane. Make that make sense.”

Not Everyone Is So Lucky…
However, not all travelers have been successful. In a viral clip with 17.4 million views, TikTok user Jenny Kurtz sips her iced coffee as she sits far from her gate. Her caption is a warning:
“For those of you thinking about testing out the airport theory, don’t do it.”
The video then shows a closed gate sign—her flight had already departed.

Should You Really Arrive That Late?
Airports and airlines recommend arriving early for two main reasons:
- They don’t want to be blamed if someone arrives late and misses their flight.
- They make money when people shop or eat at the airport while waiting.
But does that mean you need to show up hours before your flight? Not always.
How early you should arrive depends on several things:
- Are you checking bags? If you have luggage to check, you’ll need extra time. Economy passengers usually wait longer than business or first-class travelers, who get priority service. Some airports also offer curbside check-in for a fee.
- Do you have TSA PreCheck or CLEAR? These programs let you skip long security lines, but not every airport has them. If you’re stuck in a regular line, security could take anywhere from a few minutes to over an hour.
- Do you need extra time for anything? Some travelers need time for bathroom breaks, grabbing snacks, or keeping kids entertained before a long flight.
- Which airport are you flying from? Some airports, like Miami, Denver, Austin, and Atlanta, are known for long security lines and crowded terminals. Others are easier to get through.
- How important is this flight? If you absolutely must be somewhere—like a wedding, a job interview, or an important meeting—you should arrive early just in case. But if missing your flight isn’t the end of the world, you might be okay taking a risk.
So, When Should You Arrive at the Airport?
For travelers who aren’t checking bags and have TSA PreCheck or CLEAR, arriving just before boarding might work—but it’s still a gamble.
For a stress-free airport experience, most frequent travelers suggest arriving about 90 minutes before your flight.
This gives you time to check bags, go through security, and find your gate without rushing.
At the end of the day, rushing to the airport last minute is a big risk.
While some people might get lucky and make it, others will lose their seats, miss their flights, and have to rebook—all because they followed bad advice online.
