South Korea’s ‘anti-nut rage’ law is now in effect

Thinking of causing a scene on a flight?

Best not to try it in South Korea. (Or anywhere, really.)

The South Korean authorities have revealed they’re toughening penalties for disruptive passengers on flights.

This action follows a notorious 2014 incident where a former airline executive caused a meltdown over how her macadamia nuts were served in first class.

The updated aviation law, which takes effect on Tuesday, is part of a broader initiative to enhance flight safety and curb unsafe passenger behavior, as stated by the Ministry of Land, Infrastructure and Transport on Monday.

In 2014, there were 354 reported incidents during flights.

By October 2015, 369 reports of in-flight disturbances had already been recorded for that year, according to the Ministry of Transport.

Just how extreme are ‘air ragers’?

Studies indicate that passenger rage comes at a high cost.

Inflight tantrums and disturbances not only endanger the safety of those on board but can also lead airlines to reroute flights, offer compensation vouchers, and deal with customer complaints.

Heather Cho stepped down from her role as Korean Air’s vice president shortly after causing a scene over her snacks and publicly apologizing.

Cho had the head flight attendant removed from the plane after takeoff at New York’s JFK Airport, resulting in the flight being delayed by 11 minutes.

Cho, the daughter of Korean Air’s chairman, was initially sentenced to a year in prison in February 2015.

She spent nearly five months in jail before Seoul’s High Court reduced her sentence to 10 months and then granted her release on two years' probation.
