What about encouraging EI, IB, MA and FI to operate some DXB for QF connections rather than via LHR-BKK/SIN? (obviously BA won't be interested, it doesn't involve LHR) And if EK get stroppy about DXB becoming a minihub for oneworld get the NZ rights revoked.
QF's 380 order means this is pretty unlikely stuff, since it would cannibalise some kangaroo route traffic - let's face it who would go 2-stop when you could go one?
