Story highlights A plane departing southwestern China was canceled after irate passengers opened three emergency exits

Passengers were reportedly angry with the crew for turning off the air-conditioning during the de-icing process

Beijing (CNN) Chinese-style air rage is now served both hot and cold.

Last month, a China-bound Thai AirAsia flight was forced to return to Bangkok after a female Chinese passenger threw hot water on a flight attendant amid a heated argument between her boyfriend and the cabin crew over service.

On Saturday, passengers on a plane departing Kunming Changshui International Airport in southwestern China, angry with the crew for turning off the air-conditioning during the de-icing process, opened three emergency exits just as their plane was pushing back from the gate.

The flight was canceled and 25 passengers onboard were detained.

China Eastern Airlines flight MU2036, bound for Beijing, was already seven hours behind schedule at 3:45 a.m. when crew began to de-ice the plane at the Kunming airport, which saw more than 100 flights delayed or canceled that night because of snowy weather.
