Help. I have 600k miles on UAL, 600k on USair, and about 200k points on Diners, and cannot have any luck trying to get to Bangladesh (DAC). I do not have time to convert into American miles (the best partner with BA - the best choice to get there) via Diners Club (since UAL only allows 50k per annum), so what now? Both airlines' partners have no joy for me (Thai, Singapore, NWA, etc), so any ideas? The wedding is on 25 Dec, and I would be flying from IAD. I only need to stay for 5 days, and I would only consider either Business or First. Comments...
