erko221 - Be aware that even though you are buying an economy ticket and using your Gold upgrade, ticket will be expensive. A few months ago my partner, who is ROP G, was able (with difficulty) to find one seat in business BKK-LHR in April. At that time a K fare could be upgraded. It cost 49,200 THB, due to added UK government imposed business departure taxes. (Actually this was CNX-BKK-LHR.)
