A woman was removed from a flight in China after she opened the emergency exit for "a breath of fresh air" just moments before the flight was supposed to take off, local media reported.
The incident happened on Xiamen Air flight MF8215 from Wuhan to Lanzhou, which was scheduled to take off at 3.45pm on Monday.
Cabin crew had already briefed the woman about the rules when sitting next to the emergency exit.
She was told not to touch the button that opened the emergency doors, but instead she ignored the warning and pressed the button when flight attendants had their back turned.
The woman explained she needed fresh air.
