I have a question which people here may be able to answer more easily in other places.
I have cousin who flew BA about 10 months ago, and has only now decided that he wants to claim the air miles.
I know most FFP require flights to have been in the last six months. So far I've managed to cross off BA, Qatar, Finnair, American (as you needed an account before flying). Struggling to find information on the others in OW, but thought some people might have some suggestions. Many thanks.
