Hi all ! As a primarily DCA flyer and in anticipation of new options out of DCA following the US-AA merger, I'm thinking of switching allegiance from *G to AA Plat. My regular business travel is to ORD, SFO, LGA. I'd optimally like to fast track myself beginning of next year by doing the plat challenge for 10k EQP at around 6-8 CPM. If possible I'd like to do this trip in one go in Jan/Feb either through some brutal 20k MR in discount economy or a 10k in K,W but I wouldn't mind doing say 2 trips max. Any ideas or thoughts? Thanks in advance!
