Thai Airways International (TG, Bangkok Suvarnabhumi) has officially put four of its mothballed A340-500s up for sale. According to tender documents seen by ch-aviation, the jets in question are: HS-TLA (cn 624), HS-TLB (cn 628), HS-TLC (cn 698), and HS-TLD (cn 775), all of which are parked at Bangkok Don Mueang.

The Thai carrier has set a deadline of June 11 for proposals and bids to be submitted.

A bid to sell one of the aircraft to British firm, AvCon Worldwide, which represents the interests of Saudi Arabia's Prince Faisal al-Saud, collapsed in October last year when the airline's board rejected AvCon's proposed acquisition price of USD23.5million as being too low.
