If you find you’re missing some Avios or Tier Points on your account you can claim them back within six months of your flight. New members can even claim Avios and Tier Points for any British Airways flights flown in the three months before joining.
Note that you can't claim* for flights on partners, you'd have to check to see if you could claim on the partner airline themselves.
No credit will be granted for flights you flew on our airline partners prior to your enrolment in the Executive Club.
