TWO Malaysian teenage boys are suing Malaysia Airlines and the government over the loss of their father eight months after Flight 370 carrying him disappeared.

The lawsuit is the first to be filed by the family members of a passenger aboard the missing jet.

Jee Kinson, 13, and Jee Kinland, 11, are seeking damages for mental distress and the loss of support following the disappearance of their father Jee Jing Hang.

They said the airline and the government had been negligent and failed to take all due measures to ensure a safe flight.

The plane disappeared on March 8 while flying from Kuala Lumpur to Beijing with 239 people on board.

It was believed to have gone down in a remote patch of the Indian Ocean, where a search continues.

The investigation has focused on the actions of the pilot who is believed to have flown the aircraft off course.
