It was based upon ratings from Passengers. No UA did not bet AirNZ!!
Service, is one of AirNZ main ggod points and why they won 6th place!!
It went something like this Emirates, Singapore, Virgin atlantic, Lauda. In no paticular order!!!
If you donot believe me go look on their website.
My parents have flown First class on UA and NZ. They prefer NZ to UA. They said the FA's are rude, Donot create a Conversation and never answer the call bell.
Hope this helps
