Hi, I noticed that BA's mileage program is changing on 1 July. My miles are mostly on AA, since I mostly make RTs from the US to Europe/Australia (all on AA flight numbers), so I never worried much about BA.

If I add an annual RTW flight ex Aust, I'll have to go between Australia and Europe without an AA doesn't codeshare, i.e. I must take flights with either BA/QF numbers.

From what I understand, economy RTW tickets are in M class, so I'll only earn 25% of mileage on BA-designated flights and 70% on QF. Now for my two questions!

1) On the face of it, 70% vs 25% suggests that I should avoid BA like the plague (in favour of QF) if I want AA miles. Correct?

2) Does anyone see a good reason to change from AA and put my miles somewhere else? Several months ago I posted here asking whether I should put my miles on AA/QF and the resounding answer was AA. I'm now AA PLT, so it would seem that the 100% PLT bonus on AA (0.7x200=140% acutal miles) basically makes up for the 50% bonus I would get as QF gold (1.0x150=150% actual miles). Just thought I would check, though.

Thanks gurus.
