Note that what you can upgrade with Asia Miles vs BAEC points is going to be different. What is on the BA website will no doubt be on the basis of BAEC points.
OK, thanks - won't rely on the BA website then, but call and check for next flights: Just dropped off conf call and have been asked to go to Basel middle of June and middle of July

For maybe one of those I'll probably try to get on BA WT+ since timing should be a bit more 'relaxed'.
