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.

Since I'm in a wheelchair the folks were ready at the gate to assist me with the aisle chair. Once on board, the crew informed me of an aisle chair in the plane so during the flight I can use the bathroom. This was my first time using the plane washroom. Food was great.

I can't get same helpful crew for Intl flights.

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.

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. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
