Mediocre 2.0

Pros: Nothing

Cons: Flights were late for more than 20 min. in both directions. Almost missed connecting flights in both directions. Had to pay for the luggage at the airport (luggage was not included in my ticket). Flight to my final destination was cancelled (first it was delayed, but I did not know that untill I got to the gate) I was diverted to other country (by other company), had to pay for hotel and taxi, missed almost two days of my vacation. On my flight back home, they have lost my luggage... hope they will find it. Now I am trying to get refund for cancelled flight, hotel, taxi, food... I will never fly with this company by my own choice any more!!!

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.
