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 ! Thank You !

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.

Flight cancelled due to weather, the workers made it seamless.

Had to tack on extra expenses for food while waiting for the next flight. Should have gotten some type of vouchers to cover meals at the very least during cancellations. That would be next level.

First off the planes I flew on were noticeably old.

Despite the delay in boarding, we were greeted with a smile from the crew. Meal service went well and love the 3 choices of meals offered in economy

Would be nice to check-in for flight on app instead of laptop or tablet

The crew on both legs of our flight were great and did their very best to take care of the customers even in poor circumstances.

Our original flight from Sydney to SFO was cancelled due to mechanical issues after boarding over an hour late and then sitting in our seats on the tarmac for over 3 hours. The flight was rebooked for the next day, but on a much older and far less comfortable plane. The plane had no room of any kind, especially for a taller person, and there was no choice but to put your seat back if the person in front of you had. The inflight entertainment was also far less advanced. After having such an excellent flight to Australia I was highly disappointed by the flight home. Other than putting us in a free hotel for the night and paying for taxi fares there was no compensation which cost me a full day of work.

The exact timing going and coming

After returning back and the airplane taxing on the ground it takes one hour to go out of the airport gate to my riding although I have no luggage

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.

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.
