I can't see either Air NZ or Turkish doing that. Air NZ already has a partnership with Singapore/Cathay so I'd imagine they'd continue to feed into SIN/HKG. Unless they form a partnership with Turkish which I also can't see happening even though they're both in Star Alliance. What's the downside of Qatar's hub? I'll be flying QR AKL-DOH-MAN then PRG-DOH-AKL this year so I'm interested to hear your experiences of QR via DOH.
Emirates/Qatar is a good hub, but not ideal for me.
