Not so much tit for tat; rather US anti-trust rules IIRC
AA and BA cannot code-share, cannot award FF points for flying on the other's metal (US-UK flights only), cannot redeem awards on each other's flights (again just US-UK flights)
All this might be changing; there is thread on the AA forum discussing just this
