I redeemed united miles for a trip from yvr via akl to chc in the later half of April 2013 for 3 weeks and got seat class I. I presume that it is business premier. Or isn't it? Well in case it is (please let me know) there were very few seats available at all and the few that were available were almost all via Sydney (6+ hours transit wait included), the one I got is actually the shortest I could find and I wonder if I will get to sit in the premier section... No idea how it works on Air NZ... so info is most welcome... Regardless, it will be fun to see my family again in NZ after 7 years...
