Found this site by chance. http://www.FlightsFromThailand.NET Inquired for business fare Bkk - Frankfurt in August. High season for Europe. They offered 39.400b on Srilanka Airways, stop over in Colombo. That is cheaper than economy class on other airlines. The fleet is Airbus only. I would have tried it but the dates dont work. http://www.FlightsFromThailand.NET did not come back with other offers which probably means they work for Srilanka Air only. Reviews of Srilanka Air are ok, you get what you pay for.Because of my leg the overriding criteria for me is more space not food nor booth. If anyone can give a hint how to find a good business class deal in early August. My eyes are cross and wall eyed from searching the net.
