Pros: The overall experience was great! I was extremely satisfied. I thought the crew was very kind and the extra touch of bringing ice cream to everyone as a treat was perfect for our family that had to restless little boys.

Cons: I did find it strange that the only brought the drink cart around once during the 9 & 1/2 hour flight. It was a cost savings approach more than anything. For the crew, I am sure it was also a time savings approach. When going to find another drink, it was clear supplies were also thinning out.

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,
