I selected two bags on kayak but when I checked in at Air New Zealand they said I just had tickets. Was forced to pay the full price for the baggage.

Good thing, we got there.

The flight attendants did nothing and told us we had to buy water. Really?? We were over charged for our baggage by a long shot. You sell cheap flights but by the time you pay for bags it is no longer a deal.

Boarding is an issue. Please have more staff in the early stages of boarding to make sure people go to the correct lines . It's not immediately obvious and leads to frustration . I wasn't too bothered as I worked it out quickly but I could hear many others expressing their frustration around me . I was disappointed in the movie selection. I wanted more new release movies to choose from . Cabin crew friendly and polite . Love the wine ! Put up with being cramped .. would love more leg room but overall very happy ! Thank You everyone involved !

They put me in a broken seat in business class for which I had to call a flight attendant every time I wanted to adjust it.

Again, cabin crew is friendly and no last minute gate changes,

The food was gross, which could be a just a cultural difference in food tastes. There were no functioning USB charger ports on the return flight even though the ports were present. No wifi, which is a first. Most airlines I fly on these days always have some type of wifi. Lastly, the 'touch-screen' on the seat for entertainment barely worked. Buttons didn't work no matter how much you touched them. There was a delay and the selection of movies and tv were pathetic. I will not be flying Qantas again.

Very professional, nice crew, smooth flight. Loved the tail outside camera. Had fun watching that. Very enjoyable for such a long flight.

Wasn’t thrilled that only salmon salad was left as a choice for dinner. Hubby can’t do salad, and I can’t do fish. Crew brought us some snacks.

The vegan food was delicious. The stewards and stewardesses were available and friendly. The seats were bigger than the new norm. He movies and documentaries were a good selection.

The seats could be bigger. The eggs could be vegetarian.

Boarding was smooth and easy. Food and service on board was excellent. No hassle with baggage or hand luggage. Comfortable and able to use my One World Status and earn miles.

Overall service, food quality vs US airlines, selection and ease of use of entertainment system.

I purchased a $50 select economy upgrade which should have included priority boarding but it did not. That’s on the airline though, not Kayak. The airline also did not reply to an enquirer submitted weeks before the flight. Seat leg space was restricted more than average due to large black blocks in addition to the metal seat frames. Maybe that’s due to the enhanced entertainment and power outlets so can’t say it’s a complete negative.

The people and the service were top notch. I fly on numerous carriers and overall AirNZ has been my favorite, hands down, primarily because of the helpful kind friendly staff.

Disembarking down onto the tarmac, and being made to stand out there for about 5 minutes (supposedly for safety's sake) while another plane was being pushed out from the next gate, all the while breathing in the choking nauseating jet exhaust fumes while our own plane was idling.

Everything was excellent , no complaints at all. Staff friendly and efficient,food was pretty good , wine nice good flight .

Not enough good new release movie selection was very average/ poor. Your boarding from LAX could be improved. You have two signs about Premium and economy lines for boarding! These are not obvious . There needs to be a staff member or two checking people as they arrive in a line to check they're in the correct t line . Otherwise people don't trailer until they have been in the wrong line until the reach the top of the line . Leads to frustration even before the flight begins! Otherwise great job everyone !

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
