The 1st marketing carrier decides whether to apply its policy or where to defer to the policy of the most significant carrier.. AA ime defers to the most significant carrier. The eticket receipt will tell the person for certain whose allowances apply and what the allowance is and which carrier's policies apply -whatever this says is what the passenger can expect
Whichever policy applies, applies for the entire journey
If it is a hand baggage only fare with BA policy applying, then there is no additional baggage allowance for OW status applicable
