Pilot Fariq Abdul Hamid, 27, whose "All right, goodnight" were the last words from the missing MH370, is engaged and had plans to get married soon.
The son of a top state civil servant, Mr Fariq was described by his friends as mild-mannered, with a bright piloting future ahead of him.
Earlier reports painted a racier picture of the first officer of the missing Malaysia Airlines plane, who allegedly breached security rules by inviting two South African women into the cockpit during a flight in 2011.
Malaysia Airlines had said it was "shocked" by the allegation and has "not been able to confirm the validity of the pictures and videos of the alleged incident".
Mr Fariq met his fiancee Nadira Ramli, 26, at a flight school in Langkawi nine years ago. She joined Malaysia-based budget carrier AirAsia, while he flies for its rival Malaysia Airlines.
Local media reports said that Captain Nadira is the daughter of a senior Malaysia Airlines pilot. She has been given one month's leave and has been keeping Mr Fariq's mother company at an undisclosed hotel in Kuala Lumpur.
Mr Fariq, who has four siblings, joined Malaysia Airlines in 2007. He has clocked 2,763 flying hours.
He is said to have regularly worshipped at his neighbourhood mosque outside Kuala Lumpur and would also attend Islamic courses there.
Last Wednesday, a fan page was created for him on Facebook, and the page has since garnered more than 4,800 likes.
