Booked to fly on NZ80 on 31/12 and the bird is ZK-OKB. Seat map became inaccessible as soon as ZK-OKB was scheduled for this flight. Checked a few other flights scheduled to be operated by ZK-OKB and also could not pull up their seat maps (displays the "cannot select seat for this flight" message). Anyone knows why? Could it be this plane is the first cab off the rank with the new seating refurbishment?
