They magically appeared with water when I got thirsty and were all great. Veg entree from Hiltl good but a little surprising. Baked apple slices on top of mac & cheese? Sure, why not.? And 2 chocolate bars this flight!

Again could not check in online., or at self-serve kiosk at airport. General complaint to all airlines: You can do better with boarding efficiency.

Thanks for continuing to offer complimentary, hot meals on your international flights! Crew very friendly. Despite being in economy cabin, crew attempted to make it a good experience.

Long flight, bathrooms start to look ugly. Incoming plane landed way out on the tarmac, obligating passengers to be all packed into shuttle bus which took a long time to get to terminal.

I wish service could be a bit faster. Due to turbulence our second meal could not be served at all. Not sure why the passengers were not served as they were seated. Some passengers were served, some didn’t get served at all. It was a long journey coming from Boston. Imagine arriving home after 1 am without any food.

We were glad to have extra leg room at the bulk head, however, the seats themselves were extremely narrow. My elderly father found it exceptionally difficult to sit and stand from the seat. The seat table creates an ever tighter fit for someone with special needs.

Though our flight got delayed, we arrived almost on time.

Because the flight was delayed, boarding seemed a bit chaotic. Everybody tried to board at the same time. The seat had technical issues - it would either recline or be upright. The crew had to spend quite a bit of time trying to figure out how to return from a flat bed to the upright position. Entertainment was re-booted 3-4 times during the flight to get it to work consistently.

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.
