Got it — thanks for this information.
Do you happen to know if a gate agent can add something like Premier Access to my ticket? Basically I have very limited use of *G benefits, but I use them always: I usually don't check bags, so usually have a large carryon (so boarding in an early group is important) and I'm always on a 24-30 hour trip (so UC access is really helpful). It sounds like UC access is easy as long as I bring my NZ*G/NZ*E card and show it to the UC agent. Is there something similar I could do for Premier Access?
