A recent report from the International Air Transport Association suggests that unruly passenger incidents on airplanes are on the rise, increasing by 47% globally in 2022 over 2021.

In the U.S. alone, 250 unruly passenger cases have been referred to the FBI for possible prosecution.

Former FBI Special Agent Jonathan Gilliam, who was also an air marshal, told Fox News Digital that part of the reason for an increase can be attributed to the fact that even the biggest airlines are now "no-frills airlines."

"The care for the patrons is no longer there. A lot of that occurred because they got fed up with people during COVID. And the other problem is a lot of people left during COVID that were good flight attendants, and now they have, like every other industry, they have people who are just aren't customer-service oriented," he said.

Gilliam said that passengers simply "don't care."

"They really don't care. And I think you see people treat police officers the same way," Gilliam said. "This type of stuff and this type of self-centered, self-indulgent behavior is everywhere now. I mean, we see it everywhere."

Here are four instances of unruly passengers.

Chiang Mai, Thailand

While on a flight from Chiang Mai International Airport in Thailand to Bangkok, a passenger forced the entire plane to return to its original gate after a passenger became upset after leaving his bag behind.

A video recorded by another passenger on the plane shows the individual on the Thai Smile flight complaining to flight attendants about his bag that was left behind, which contained valuable items, including money.

At one point, a flight attendant grabbed his arm in an attempt to force the passenger back to his seat.

"If you still feel like this, we have to move you off the flight, so do you want to go? Or do you want to wait until Bangkok?" a flight attendant asked the man.

"Yes, yes, I want to go now. Ask the captain," the man replied.

The plane then returned to the terminal, pushing back the flight that was already delayed by 45 minutes.
