,,, I flew to SFO last May with Air NZ. I took UNITED to Chicago, Lexington and Montreal, then Air Canada from Montreal to Vancouver. I think AIR NZ do a pretty good job. The best I've had was SWISSAIR (not flying anymore) and SINGAPORE AIRLINES. Also, I did a few routes with Cathay Pacific and they're pretty good.
I've paged someone who was staying with us last month who took AIR NZ down here and back home for his opinion.
As for the advice AIR NZ offered to the crew, they have to be aware of characteristics in markets where demographics and expectations differ.
