I suspect the questions have been asked and answered numerous times on this forum, but I will ask it (again) nonetheless. I will not ask about the seat specifications - as that information is in the sticky thread.

In terms of the flight attendant service, what are the differences (in this case - for example between Honolulu and Auckland and between Auckland and Sydney) between the premium economy service, and the 2 other classes of service?

I would like to look at the fares (either by using the KVS tool, or the expertflyer tool). What the booking codes corresponding to premium economy class of service?

Thansk,
