Shiney jet syndrome will win over, Jetstar NZ just offered the wonderful opportunity in AKL to transfer to the A330 for the SAME pay as a FO on the A320, union said don't take it, other pilots said don't take it, but 10 First Officers signed up on the first day just to get the A330 type rating
We are our own worst enemies
