Excellent 8.0

I had an episode of anxiety over very minor turbulence which I sometimes get and both ladies who happened to be on duty were very reassuring and sympathetic to me. I had my 6 year old daughter also on the plane who is not anxious at all, so I was able to speak to one of the staff in French so as not to transfer my anxiety to my daughter who doesn't understand French. This was great. Over half way through the flight they gave me some earphones and suggested I watch a movie. This helped so much.

Nice, friendly crew

Sold me headphones that were very poor quality. Couldn’t use them. No snacks provided on a very long flight-all was for sale. Drink was a bit more than half a cup

Flight cancelled due to weather, the workers made it seamless.

Had to tack on extra expenses for food while waiting for the next flight. Should have gotten some type of vouchers to cover meals at the very least during cancellations. That would be next level.

The flights were great, on time and no problems. I was very comfortable and the food was good. FLight attendents were great except one guy who was not friendly and needed a vacation or another job.

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.
