On the ground the Qantas lounge is a much better offering than Air NZ's, starting with the barista! The Qantas lounge has improved heaps over the past couple of years.
In the air the yanks can have their bad days just as much as QF - food and wine on Qantas is the better too. If you fly on the A380 - there's no competition when it comes to seat and IFE.
Pacific doesn't even come close to QF.
That all said.... is it worth the extra 2-3000 dollars for QF??
