This is the stomach-churning moment a young airplane passenger annoyed other fliers when he was seen - picking his TOE NAILS.

Jade Thomas and her boyfriend Trong Nguyen were onboard an AirAsia flight from Kuala Lumpur, Malaysia, to Hanoi, Vietnam, on Sunday afternoon.

They noticed the young passenger across the aisle without his shoes and socks - while wearing a surgical mask to protect himself.

They were horrified when he put his dirty feet on the seat in front of him before picking the dried skin from his feet and dropping it on the floor.

He continued to pick the fluff under his toenails, oblivious to the hygiene problems it could cause for other flyers on the packed Airbus A320.

Jade, originally from Queensland, Australia, said she saw the man picking his feet and ''felt sick''.

She said: ''I was returning from a trip to Bali with my boyfriend.

''During the flight, we also observed some poor behavior that is not uncommon on these kinds of flights.

''There was shouting, loud burping, not following requests of airline staff, for example, everybody stood up and started getting their hand luggage before the seatbelt sign had been switched off.

''Then. of course, there were some people not wearing shoes.'' Jade had been in Bali, Indonesia, before flying to Kuala Lumpur to catch a flight onto her home in Vietnam, as there are no direct flights from Bali.

The flight left Malaysia at around 12.55 and landed in Hanoi at around 3pm. She made the video while the plane was in the air.
