don't see why an A320 couldn't comfortably operate into Rotorua (assuming Rotorua is anywhere near 17-1800m).
Landing distance is
less than 1600m and elevation 935' - it's very tight.
Because JetConnect salaries are so low that even Jetstar crews would gag.
Jetconnect salaries are similar to Air NZ 737 salaries. Australian wages are around 30% higher than NZ across the board. It sucks but that's the reality.
