The flight crew was kind.

Good evening, I’m not sure under which category our complaints should fall on your website so I will include them here. To summarize our complaint, we booked our tickets on Icelandair through Kayak (and Webjet) and upon arriving at the check-in counter on December 2, we were informed that the baggage fee for our flight would be $95 each! Understandably, we were shocked and very displeased. Nowhere in our confirmation emails or flight details was there anything about having to pay such a high rate for our luggage. The first employee we spoke to said that your airline has recently started charging such fees to compete with WOW Air and as I said to him, I would like to point out again that this is the very reason why I never choose to fly with WOW Air: they clearly state that there is a high baggage fee from the beginning of the registration process and I know of too many other airlines who don’t have such inflated fees. This ticketing agent and the manager said that the level of our ticket (apparently called Economy Light) indicated that we would be charged this baggage rate. It is now my understanding that on the Icelandair’s website, these levels are described but no such options were listed or explained on the Kayak website or any of our confirmation materials/emails. It is the responsibility of your site to post these important details in a conspicuous place so that travelers can make informed decisions. We could’ve flown with Air Portugal for a mere $50 more and saved not only over $200 each but also the inconvenience and frustration. Upon the check-in manager’s suggestion, I looked up our flight by the booking reservation number (LCWNEG) and again, the only “flight type” shown was called Economy, nothing more. The same is true for when we checked in online and reserved our seats - there was never an indication of the fees that were awaiting us. All this to say, we were incredibly upset to be surprised with an additional cost of $200/person (round trip ticket) but then, to add insult to injury, not only did we nearly miss our flight due to the length of time spent at the check-in desk, once we got on the plane and we realized we would not be served anything other than water or soda - since all food/meals must also be paid for in most Economy levels. This was our first experience with your airline/website and I highly doubt we will ever choose you in the future. I know now for a fact that other passengers who have booked through 3rd party sites have found themselves in similar bad situations. If you choose to work with airlines and offer lower rates, it is only honest and fair to make your policies clearly known to your potential customers. We felt mislead and deceived as these rates seemed hidden until it as too late. I eagerly await your response and look forward to hearing what steps will be taken to rectify the problem and make amends for this unacceptable situation. Sincerely, Mandi Vermilyea and Judith Arp

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.
