(7) What is most important to you in a FFP? (upgrades on travel, priority services when flying the airline, extra baggage allowance, good award redemption rates, better award access, free - discounted lounge access, etc.)
Better access, especially in business class

(8) Preferred Airlines
I like BA, haven't flown many other OW carriers other than AA.

I'm a member of both AA and BA, have had both credit cards (no longer have BA's), but seem to prefer BA's program to AA's. I just did a big redemption of OW miles for half a RTW trip.

So my question is: I'd like to drop one of the two programs, but which one?
