Hi-

I'm moving to Baltimore in June, for the next 7 years, and though I don't expect to be travelling every weekend, I'd like to move all my flying to the "best" airline at BWI in terms of availability of flights...

I'm currently AA Plat. Should I stay on or switch? I'd probably be taking occasional flights to SFO/SJC/LAX and BOS/NYC.

And while I'm here, what's the best way to get to Boston from Baltimore--Amtrak? Fly? Drive? Thanks everyone!
