All was easy

It wasn't super comfortable

It felt like there was more leg room than on the US airplanes.

I thought the food was just okay.

The plane was new. The crew was awesome and the flight short.

LAX
Okay 4.0

Flight left almost on time and arrived on time. Crew was friendly.

Wasn't able to select a seat ahead of time like with other airlines. Seat rows way too tight (even for a normal 130 lb person like me). No good movie options, very limited selection. Food pretty bad, but that's almost expected this day and age.

Excellent 8.6

Ground staff and crew excellent Boarding was confusing and not announced

The breakfast was kind of gnarly - the eggs were oversalted and slimy, like worse than the usual airplane meal

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.
