taupo, I'd assume that, while the booking classes are effective immediately, they'll remain as they used to be on 747 services until the 74R enters service.

AFAIK NZ itineraries don't show seat numbers - did you call AC? If you did, I'm willing to bet that AC requested the seats 1JK, however from memory Row 1 is blocked off for airport allocation due to having bassinets. When an AC agent requests seats from NZ, it will send off as "NN" (need need) status and NZ will send back a "KK" (konfirmed). Agents shouldn't confirm seat assignments that remain on "NN" status.
