Toilet door comes off during 16-hour Cathay Pacific flight from Hong ...

Hong Kong flag carrier Cathay Pacific Airways has launched an investigation after a toilet door came off mid-flight.

Photographs of the incident believed to have been taken by a passenger and circulating online showed a female flight attendant in a cabin crew seat with her hand holding the detached door.

Another image shows two individuals standing beside the door on the Airbus A350, seemingly offering assistance.

A caption accompanying the images said the door came off three minutes after take-off.

Flight tracking websites showed the flight landed at New York’s John F Kennedy International Airport 16 hours after it took off from Hong Kong at around 5pm on Monday.

In a reply to the Post on Tuesday, the airline said it was aware of the defective door on flight CX840.

“The defect was rectified and our engineering team is performing a follow-up investigation,” the statement added. “The safety of our customers and crew guides every decision we make. We apologise to our customers for the inconvenience caused.”
