OR

If you are able to optimise your flight patterns, ticket types and/or AAdvantage butchers earnings rates, these parametres are no longer valid.
Yes I think I'd agree to go AA too as you are doing mainly Y flying. You will get status quicker on AA.
Caveats are
1) No lounge access in the US for domestic legs (but buy Admirals club membership instead if you miss it)
2) Its better to have status with the airline you fly with most - it just works better, and you should get preference for any upgrades or during service issues
3) Your patriotic American company should be told it doesn't matter which flight you take transatlantic (AA code, BA code, AA metal Ba Metal) as is all shared between the companies anyway.
4) You have less options to top up your AA balance as a UK resident than with BA from non-flying stuff. No 2-4-1s on Amex either, though I note AA does have a UK credit card
