Seats were comfortable ... enough. Boarding process, once underway allowed me to get overhead bin and stash my other luggage in the seat below me. Flight wasn't overly booked (85-95%) so there appeared to be room for others to stretch out. Now about that crying kid...

Ugh. Weather delays. The flight was scheduled to board about 7P but it arrived late and they had to not only unload the self-loading cargo, but clean up afterwards. Would be nice to get a better estimate as to how long it would take to board so that I could hang out in the lounge. In addition, departure from JFK was delayed as well, either we missed the IFR window or got stuck behind some traffic and I fell asleep on the plane only to wake up what seemed an hour later just getting ready to hit V1. No upgrade.

Nothing, they didn’t care about you or to help, the llady was so rude and unfriendly, this situation ruin my whole trip

I call in advance to paid the fees for baggage, I call Aeromexico because was the main airline for the fly, but Delta at Seattle made me paid again the fees for baggage’s even by phone they said that I didn’t need to paid. BE AWARE AND CAREFUL BECAUSE THE LADIES IN THE FRONT DESK didn’t even look the paperwork that you have in hand, they only want to charge you saying that your payment thru Aeromexico didn’t help you in the 1st fly. How this can happen when Delta and Aeromexico are two subsidiary one of another ?

As always, the crew and amenities were first rate.

We were initially told that our flight would arrive early. Then we sat on the tarmac for a half hour before anyone could be bothered to tell us we were waiting for the plane to be de-iced.

My United connecting flight was delayed. I rushed to arrive at the gate prior to the departure time to be told the plane had left early and I had been rescheduled to the next morning at 7am. However, there were no vouchers available for me to stay in a hotel or get food. So, I was able to get a flight on American that got me home the same night. By the way, the American flight was delaying takeoff to wait for passengers who had been delayed on their connecting flights.

They staff was friendly and they boarded efficiently.

The worst part of the flight was the fact that they have redesigned their planes. They have put the seats even closer together and their new seats are horribly uncomfortable. The seats are made out of a hard molded plastic. There is no give and they don’t form to you back at all. Their comfort level I would rank at a zero! I had thought they may not be bad for a domestic flight as mine was international, however, I also had them for a domestic and they were equally uncomfortable. I will be checking off of United on my next flight as I can not sit in a seat this uncomfortable ever again! Try again United!!! #UnitedSeatsUncomfortable, #HorridSeats,

My seat was comfortable, with good head and neck support.

BA doesn't allow guitars as carry ins, unlike most every other overseas carrier. That's a major negative for me, and I've spread the word to other musicians who will avoid the company. Terrible policy.

Seats were comfortable and staff was very attentive as well as respectful of us when I was sleeping

There was condensation leaking from the ceiling of the cabin. A crew member said this was normal, would have been nice to know this ahead of time to reassure me that for a first-time overseas flier that this is normal.

British Airways overbooked this flight and made it unclear if I can board my flight. Overbooking is such a greedy behavior and airlines should refrain from engaging in this dubious policy. It is the second time this happens to me with BA.

It does the job of taking you on time to the place you are flying to. I had forgotten that you have to purchase food but I find that much better: a lot less waste that on airlines where it is provided.

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

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.

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,
