Nothing really.

Boarding process was horribly handled. Food was inadequate. Stewardess was saccharine. Bathroom door didn’t shut completely. I was told this wasn’t an international flight and therefore no free alcohol. Aero Mexico flight to Mexico City had much better food, free alcohol and more attentive service personnel. Also delays because of equipment problems.

The plane was really cool. Some more advanced technologies than other Airline companies. Crew was good too.

Issue happened with my landing. Didn't make it in time to next gate. Delta did everything they could to blame me, insulted me on The phone and definitely provided the worst customer service

Glad to have lots of rice options for food!

We booked with ANA but got put on a United flight on the way back. ANA was so much nicer. We were really let down flying United, having booked an ANA flight. When they swapped our flight, they didn't seat us all together either. United crew should take lessons from ANA!

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
