Delta's response to One World
 

Does anyone know if Delta and its Qualiflyer partners plan to integrate their frequent flyer programs so that they are recognised by all partners like on One World with their emerald, ruby levels etc.?

That would seem to be a logical idea, but I'm wondering how that would affect Delta's relationship with United (or lack of relationship!)

But remember that in some cases (NOTE: SOME)
Delta goes backwards instead of forwards when
it comes to frequent Flyers. CATMAN

I don't bet - if I would my answer would be NO. Even more NO if I look at the current discussions/speculations/rumours of anticipated changes of partnership in the near future:

*Delta with Air France (this makes Swissair mad)
*Swissair (with some Qualiflyer daughters like Sabena, Crossair, AOM; and some Qualiflyer partners as Austrian) is in discussions with Oneworld.
