Austrian Airlines have brought in a 'bid for an upgrade' scheme similiar to other airlines. I am flying from London to Bangkok in August for my honeymoon and would love to go business class. I paid £600 for my return flight and the business class option was £2200 at the time. We just want to uograde on the flight out from Vienna to Bangkok. Anyone have any idea of how much we should bid? I was thinking in the region of £600. I have researched what people have paid for similiar upgrades on Eithad but their flights were all generally shorter by 2000 miles.
