The PB contracts are being tossed in favor of some other arrangement, then one can assume that the airline is in some sort of talks with it crew re various employment models/options and Finally some more $$ .
I would have it a guess that any
VB guys operating on PB routes, receiving a pay slip twice that of there Kiwi cousins, may end up causing more than one or two problems between the two groups. If the roll was reversed and
VB needed to crew an additional 50% capacity overnight, I'm sure the thought of foreign crews operating
VB routes at twice the pay would unsettle a wasps nest............
