I've been on AA forever, bouncing around from GLD to PLT to EXP and back again (lifetime GLD right now). I have a legacy BA account (renewal date is mid-August). My traveling habits are about to change wherein I'll be going to London a couple of times a year and travelling NYC-ROA (on a mix of AA and US) every week. Wondering if I should stick with AA or move to BA where the qualification to Silver might be easier than Plat on AA. Opinions?
