Bangkok Airways has begun an internal study on the possibility of being listing on the Stock Exchange of Thailand (SET) by the end of 2013.
The privately owned regional carrier could float up to 30% of its shares in a listing, said a spokesman.
It aims to raise funds to expand its operations, he added.
Bangkok Airways is targeting a minimum revenue of baht (Bt) 10.6 billion ($354 million) this year, up from Bt8.3 billion in 2010, the airline said on 3 August. Its revenue for the first half of 2011 reached Bt5.2 billion.
The carrier could also add more international services and branch into the low-cost market, added the spokesman.
However, these plans are still in the "very early stages", he said.
Bangkok Airways on 14 July inked a codeshare agreement with Singapore-based regional airline SilkAir. It also plans to deepen its codeshare partnership with Finnair, Malaysia Airlines and India's Kingfisher Airlines.
The airline operates six Airbus A319s, three A320s, and eight ATR 72-500s. The company has four A350-800s and three A319s on order, and options for three ATR 72-500s.
