A cursory glace for me on the air nz website still shows flights departing Kerikeri for Auckland at 0655 over the next three months. All of the fares I saw had 'seat' tickets available for under $80. Whats the issue?
If Air NZ can't make money out of services like Wanganui, why should they have to continue? Air Chats is already making noises about taking that one over...
