The YVR route has been on the rumour mill for a while now. A very welcome expansion for NZ, and once the AC fleet refit is sufficiently advanced, the AC product will be quite acceptable, I think.
I know NZ moved heaven and earth to have the US authorities allow the transit arrangements for the pax on NZ1/2 - even though they are less than ideal, and you still have to suffer the US entry process, at least you don't have to reclaim your bags, if you're staying in the transit lounge.
Despite that, one can't help wondering if NZ would move the LHR flight to transit through YVR as opposed to LAX, or whether the LAX O&D pax make it worth while keeping that flight routing through LAX?
I think they do have a fairly strong O&D following on the LAX route.
Talking of which, in the article is news that NZ1/2 will revert to 744 from the Northern summer, which will mean two NZ 744s in LHR every day. This releases 772s for YVR and other new routes.
Cheers,
Mike
