If I could give half a star I would and I haven't even taken the flight yet. I booked a return flight to Auckland from Sydney for my wife and myself, a family reunion. Due to some mis-communication I had to change the dates of departure and return. I expected a change fee but was gobsmacked to be hit with a bill for $400. Yes that's right $100 per person per change both ways. This is simply extortion or legal theft. I myself made the changes online so operator intervention was minimal. Updates to records take place in nano seconds so where is the justification for $400? Perhaps checking availability? Nope, this was checked by me prior to making the change. All flight times are the same, even the flight numbers are the same, just a week earlier. The only explanation I can think is that it is done because it can be done and you the customer can do nothing about it. Airlines and airports are totally out of control. The change fee plus all the other add on costs come to more than the flights cost. Perhaps if Air NZ cancel the flight I will be able to bill them for $400. Fat Chance!
