Hi All, thanks so much to all the 'regulars' answering lots of these questions. Here's my particular case.

For historical reasons I've always been a Qantas member, and have just about got my lifetime Silver (which is only bronze for BA). I'm living in London permanently. So the question is whether to ditch QF and start over with BA? One thing to consider is that I'll seldom fly Qantas so I wont be able to use the status from year to year unless its a 'lifetime' impact (because of their 4 flights minimum). I'd imagine it will take another 7 years to get from 7000 SP to lifetime Gold 14000SP on QF (14000 points, 'silver' equivalent on BA). So I think I should be concentrating on mileage and upgrades?

Many thanks for your help, Giles_G
