Pros: I do like the clean aircraft, and pretty precise service. Also it was on time , for comfort the pillow and the blanket was nice . Some airlines doesn’t give anything anymore! Which is awful.

Cons: Just a small thing the lady who was serving and picking up the used cups said I have to finish the juice and after she can take it away. But I couldn’t finish because it was too sweet and I didn’t like the juice. So I had to get up and bring the cup to the back. That wasn’t nice. Also they at but flexible about giving choices. Only one kind of sandwich they had but I think there was one other kid also.

Pros: Did not take the flight in the end

It was incredible frustrating and could have very easily been avoided with communication from the airlines

Pros: Seats in economy are never comfortable. And someone also reclines their seat. But overall bathrooms were clean and food was good. Really no complaints about the flight itself or the crew!

Cons: Carry ons are too big! People should not be allowed to bring a piece of luggage inside the cabin. They are very heavy and some people cannot even lift them to place them in overhead compartment. Makes boarding slower and more complicated. Seats need to be a little wider. If a big person sits next

Good 6.3

Pros: The new boarding process (just one general call, rather than a bunch of zones) was simple, quiet, and efficient.

Cons: The seats were very uncomfortable. There were small ridges on the left and right side - perhaps to compensate for the very shallow seat depth. But these made it hard to sit more on one side of the seat than the other, something you'd want to do if you were sat next to someone who took up a good deal of armrest area. Media screens had a good selection but were unresponsive and had poor picture quality.

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,
