Looks like a turn-around.
MAS in a statement said the previous flight number of MH370 for flights from Kuala Lumpur to Beijing would be revised to MH318.
Its return flight MH371 would be changed to MH319. The frequency of flights remains unchanged.

Maggie,
I think hoosiermama was wondering where the flight originated before coming in to kuala lumpur, and whether it had fuel left over from that trip.
and if they gassed up at KL they would have had more than ‘ just enough + extra’ for the flight from KL to Beijing.
