Re: New Zealand Aviation Thread - September 2022

An A350-900 and eventual -1000 order keeps sounding more and more attractive. Boeing is like that abusive boyfriend who Air NZ keeps going back to. I would imagine that NZ is a pretty tough negotiator, and probably always wants the cheapest deal. They lived the dream with the launch customer discou...
