The Premium Economy seats were very comfortable and the food was quite tasty. I did not use the entertainment system, but I was able to charge my phone and tablet with the seatback connection.

The Premium Economy seats were very comfortable and the food was quite tasty. I did not use the entertainment system, but I was able to charge my phone and tablet with the seatback connection.

Nothing better than Air New Zealand. Top scores in every category.

Your entertainment could be better. I flew on Air New Zealand in January so was expecting a better choice in February...but no luck. Same choices and also could have a better selection. Otherwise, lovely service, the purser came to our seats to welcome us. Overall, very nice. Direct flight from Auckland to YVR was fantastic!

The disembarking steps in Wellington were precarious and I felt quite insecure. There was no one on the tarmac to greet us and help. The embarking ramp in Blenheim was much more satisfactory. The rest of the flight was fine.

They are my favourite airline in the world by a million miles.

Again, Air New Zealand was great. They kept bathrooms clean, food was actually very good, New Zealand wines a big hit

It was good for a short domestic flight. As no food ar entertainment provided, there should be a n/a rating available for those.

Nothing special short flight - all good - difference between 1 fudge and 2 fudge is obligation and thankfulness

Major hassle with the weight of carryon luggage Having to repack bags at airport Not an issue in most of world Ridiculous issue considering the 400 pound gentleman sitting behind us

Overall good. We had to transfer to Bradly terminal. We had requested wheelchair assistance. The bus that picked us up had to wait for other passengers. The wait was long. Then, at the Bradly terminal we had to wait an extended period of time for the wheel chair assistance. These delays caused tension at checked in and resulted in arriving at the gate as passengers were boarding.
