Bangkok Airways plans to invest in new routes, aircraft and airport improvements in a bid to turnaround its fortunes.
Last Friday the airline reported a 55% drop in net profit for its 2017 fiscal year.
The carrier plans more charter flights to China, and new routes from Chiang Mai to Hanoi and Phuket to Yangon this year.
President Puttipong Prasarttong-Osoth said the airline expected to receive two Airbus A319 aircraft this year, with plans to replace six ATR72-500s with new ATR72-600s to maintain a fleet size of 38 aircraft.
It planned to build an aircraft repair centre at Sukhothai airport, and upgrade its airport at the resort island of Samui.
Revenue was expected grow 10% this year with passenger numbers rising 7%, Puttipong said.
