Vietnam Airlines incurred a loss of around US$10,000 after a passenger opened an emergency exit after his aircraft landed in Ho Chi Minh City Tuesday, VnExpress quoted an unnamed official as saying.
The evacuation slide was released when 29-year-old Le Van Thuan, who was arriving from the central city of Vinh, opened the door, meaning the airplane could not be used for its next scheduled flight, VnExpress said.
Thuan admitted he had been reminded of safety rules by the flight crew, but still opened the door hoping it would help a woman seated near him exit the airplane quickly since her baby was crying.
The newswire said he opened the door immediately after the crew announced the aircraft had landed safely.
It quoted the official -- who works in aviation security -- as saying Thuan would probably be fined VND15 million ($720).
Last year a Vietnamese university student and a Taiwanese were also caught opening emergency exits and fined VND15 million each.
