On board a Vietnamese search aircraft
Vietnam has set up command posts at Phu Quoc island - the closest port to the plane's last known location - and Ca Mau airport on the country's southern tip.
It has dispatched a total of eight ships and seven aircraft and is expected to send more.
The BBC's Nga Pham accompanied the crew on one of the search flights from Phu Quoc.
