Pros: The arrival gate was extemely close to the departing gate. I did not have to walk the usually long and exhausting distance from one terminal to another. Thank goodness.

Cons: Broarding was well organized by groups andmoved quickly. The choice of dinner was not an option. By the time the stewardess reached me, only pasta was left. But having italian gelato for dessert was an acceptable compensation. Breakfast ,however, was ho..hummm without any redeeming compensation. choice of beverages was refreshing.

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.
