My partner and I are flying LHR-SYD in business class with Asiana in March, as Asiana had the cheapest C class fares of any decent carrier. We are not a member of any FFP other than BA Exec Club and therefore will get no points for this journey, however this seems a waste! Which airline's FFP would be best to join? I fly a lot but there is no point me joining the Asiana FFP as I almost never need to go to Asia and therefore probably won't use them again for a long time, however good they are.
