Bangkok Airways expects to take delivery of its first Airbus A350-800 in 2015.
The carrier has a total of four A350-800s on order, but has not received a firm delivery schedule for the subsequent three, a company spokesman said.
The spokesman added that Bangkok Airways does not have immediate plans to convert its A350-800 orders to A350-900s.
Bangkok Airways also has two A319s and one A320 on order. The carrier expects to receive one of the A319s in November this year, and the A320 in October 2012.
The airline operates six A319s, three A320s, and eight ATR 72-500s.
