Jeanes, the passenger, had planned to propose to his girlfriend Casey Kinchella in Bali, but pulled down his oxygen mask and did it on the plane.
"Luckily she said, 'yes,'" he added. "We both reconfirmed with each other when we were on the ground."
The budget airline said in a statement the pilot turned back “following a technical issue to ensure the safety of passengers.”
“We commend our pilots for landing the aircraft safely and complying with standard operating procedure,” AirAsia Group head of safety Captain Ling Liong Tien said. “We are fully committed to the safety of our guests and crew and we will continue to ensure that we adhere to the highest safety standards."
The Australian Transport Safety Bureau, an accident investigator, said it was investigating the airliner’s depressurization at 34,000 feet.
The plane rapidly descended to around 10,000 feet, an altitude to which cabins are pressurized and at which oxygen masks are no longer needed.
Data from FlightRadar, a website which tracks flights globally using GPS, shows the plane descended 23,800 feet in the space of nine minutes.
