The whole "geography " of FF awards can be crazy making although sometimes it provides great advantages...last year I was very happy that United miles could buy a *A flight SFO-Vienna-Yerevan for 80,000 in business, apparently Armenia is in Europe!
However, this year I'm not so happy to find that while Sri Lanka is in South Asia (60,000 in economy from the US) Delhi is in Central Asia (80,000) ...Oh well, perhaps I should change my vacation polans and go to Uzbekistan which United assured me is in Europe and the routing from SFO would take me via Seoul on Asiana!!!
