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

Excellent 10.0

The crew were professional and looks the part, food was warm and tasty and they made regular checks to see if we needed water or food.

Well there were 3 crying babies for a good portion of the flight which is no fault of the airline or parents it's just something that wasn't as desirable.

747-400, new seats with more legroom. Awesome selection of movies, TV & documentaries.

Tray table would not stay up - steward gave me stickers to hold it up.

Mediocre 2.6

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.

Good 6.0

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.

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 !

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.

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.

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.

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.
