I'm planning my next trip to Europe. Using my favorite flights/schedule, the option with 3 EK legs and one QF leg (operated by EK as a QF code share) is $600 less than the same itinerary with all four flights under EK codes. So it would be EK/EK - two weeks at destination - QF/EK.

Of course I can earn FF points in either EK or QF on all these flights, but I'm more interested in tier miles (status credits in the QF system). I'll miss out on EK tier miles on the QF code-share, but is it possible to get the QF status credits for that flight? In short, can I assign my QF FF number to one flight and my Skywards number to the next? If I start with the Skywards number on the booking, fly to Europe, then change the FF number from Skywards to QF, fly the QF segment, and then in DXB (10 hrs), change it back to Skywards, will that work? Potential pitfalls? Any way to do this in advance rather than progressively?

For the return trip both BPs would show the QF number. As Silver I don't () have lounge access at the European port anyway, but at DXB I would need to get the number changed back to Skywards to get lounge access. Otherwise I think this would work.

Thoughts? Experiences? Funny stories?
