Wondered if someone could help? My parents are off to Australia/ New Zealand in February on a RTW BA/QF economy ticket. Not being a oneworld person (all my travel Star/ CO)I wondered which FF programme to advise them to join. They're based in the UK, and travel to US/Europe mainly on cheapest fares (they've just retired)So aa/ba or qf? Thanks

ps they booked it without checking with me first
