Seeking answers to a few question Scenario: If I fly on Airline F(Flown) and credits it to Airline M(Mile), Is it better to book through Airline F or Airline M?

If lounge access is involved, which FFP rules will apply or they combines? Which airline will get the flight (segment) flown credit? Airline M is definitely getting the redeemable miles Which airline will get the lifetime miles credit? Thanks!
