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

Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again.

From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew.

The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!

Our flight from BLR to FRA got cancelled because of bad weather. The agent at the check in desk immediately put us on an alternate AIr France flight via CDG to LAX, which left an hour before our FRA flight. The service on the flight was excellent. But we are most thankful for the quick re-booking on a different alternative, ensuring no hiccup. We will only be flying Lufthansa from now on, and recommending Lufthansa to all friends and colleagues.

This has nothing directly with SAS, but since I experienced it during my flight there, they are responsible of it. I was waiting for the flight at the OSLO airport waiting for the flight to LONDON. I had ample time to work on my computer. In the big room by the gate there was only one spot where I found three electrical sockets hanging from a pillar or post. To my dismay none worked. My plug would fall off from each. To document, I took the pictures of the useless sockets... I complained to the lady at the boarding desk (she left before the SAS staff moved in), she did not even care... This experience frustrated me and turned an otherwise pleasant trip into a bitter one. Please install some working sockets in your waiting room!

The crew passed by me TWICE while serving food and I was not sleeping at that time. I had to go and ask for food myself. Also there was a delay about 40 minutes when taking off in CPH (CPH-EWR) because of a fuel-screen malfunction or smth. The pilot was very nice and kept us informed all the time. I still didn't make my connection flight due to the delay and SAS rebooked me which made my already long trip 8 hrs longer.

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,
