This is a naive question but after all the KLM/AF and SkyAlliance stuff goes into effect (which is supposed to be mid-September), does that mean I can use NW miles to upgrade on, say, AF flights? I travel alot BOS-CDG connecting through AMS, using a B fare which I upgrade with miles. But there is a direct AF BOS-CDG and it would be great if I could do the same thing on that flight. Also, would the miles I get on AF flights then be useable on NW, etc.

Thanks in advance.

PS Is there a link which discusses the implications of all this for WorldPerks?
