An aircraft steward believed he was comforting an Australian woman when he allegedly put his hands down her pants on a Malaysia Airlines flight, the female passenger has revealed.

Channel Seven's Sunday Night will air a tell-all interview with 26-year-old Laura Bushney, who recorded the moment Mohd Rosli Bin Ab Karim, a married man with three children, put his hands under a blanket and down her pants while working.

Mr Rosli allegedly touched Bushney's upper thigh before putting his hands under her clothing after being under the impression he was "comforting her".

"He's massaging my legs, I'm so scared I just want to get off this plane," Bushney can be heard saying on the recording. "I don't want to see you, go away, you give me the creeps you dirty old man."
