The flight had no pilot assigned to the flight yet the attendants still boarded us. Then we waited on the plane for an hour before exiting the plane. The attendants gave us little information on flight alternatives and when the flight was finally allowed to board again, they did not announce it and so had I not been waiting close by, I would have missed my flight. It was extremely disappointing but not shocking with all the scandals that have occurred this year with American Airlines. I do not recommend flying with them.

One of the flight attendants wanted to be a stand up Comedian. It was a little trying but my wife liked his routine more than I did.

The plane took off over an hr late due to lack of heat and the pilot had to reboot the system, once the plane finally took off the flught attendsnts then explained they would start the beverage service but were iut of most options and we could get ready to pay for what was left, maybe if they offered complimentary beverages at that point would've been a nice touch.

The seats were really bad, it was our first trip on a 787 and I will never do it again. Not as bad as the Airbus from MIA but considering it's 13 hours it was totally rubbish. We normally fly the 777 with Air NZ, after this we will go back to them. The staff, as always were helpfull and pleasant, the plane was quiet but the seats.....

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,
