I'm thinking of switching to OW from *A (UA). I am BD*S, so will become BA Silver as of May1-ish. I could also obtain AA PLT right now based on my Premier Gold UA status, although if I go AA I may be better to wait until June 16/July 1 and pay for a challenge as I have a SFO-LHR WT+ trip in July which will easily get me >10k EQP and then I'll have status until Feb 2014 right?
