A statement on the Malaysian Airlines website noted that the MH370 flight code, marking the Kuala Lumpur to Beijing route, and the corresponding MH371 code for the Beijing to Kuala Lumpur route, will be retired from 14 March 2014 as a mark of respect to the lost passengers and crew of MH370 on 8 March 2014.
The replacement numbers are MH318 for Kuala Lumpur to Beijing, and MH319 for Beijing to Kuala Lumpur.
According to the statement there are no changes to the frequency of the airline's services, and the double daily services to Beijing will continue.
"Our thoughts and prayers remain with the families of our colleagues and passengers of MH 370," the statement concluded.
As of 12 March 2014, there have been many theories and false alarms since the plane lost contact in the early hours of 8 March, but no definitive conclusions as to where the plane is, nor what has happened to it.
