Excellent 10.0

Pros: Reasonable fares. Good baggage accommodations. Denver to Iceland direct. Nice flight staff. The flight attendant pointed out the people who were awake the northern lights which was definitely the highlight of my trip!

Cons: Seats small. Surprised no meals unless purchased. But didn’t matter too much I ate before the flight left. And it was nice to have something to purchase if needed. It was confusing where I could purchase my baggage ahead of the me while checking in online so I just paid for it once I got to the airport.

Pros: The crew was reasonably friendly despite the circumstances

Okay 4.3

Pros: Food was ok

Cons: Who starts a boarding process 2h before the flight with only 2 counters, with no possibility to check in online (even for those without luggage) and no automatic machine? I'm very glad the company had the kindness to wait for us on the last call for boarding when you finally check your luggage 30min before departure. Should we talk about the politeness of your fight crew? In short, very disrespectful. Delivering the luggage took an extremely long time

Good 7.3

Pros: The entertainment was great.

Cons: It was hard coming home since we can't bring any food with meat on the international flight coming back to the USA. Or at least the food I brought, a sandwich was not allowed because of customs. I can't eat the food that was offered. I'm glutten intolerant and dairy involerant. Not sure there's a whole lot to do about it besides buy prepackaged food that don't have meat, vegtabjes or fruit. Protien bars may have worked. We brought two bottles of water each from the terminal. I could have used more, even with the drink service. The flight attendants we're having thier own personal conversation while passing out food and ran by when it came to the final trash clean up. When I got up to use the facilities I tried throwing my trash away but was ignored by a crew member while she was resting.

Pros: The flight AMS to MEX was smooth, very helpful personnel on board, we enjoyed a bit more space and the seat seemed a bit more comfortable.

Cons: Besides the seat relative comfort, it did not recline much at all, i wondered what the extra money (at least $5 or $600) got us. The food, wine/ beer service was same as regular economy, the boarding took place at same time as economy, no drink before take-off if only sparkling water. And the plane was old generation 747 and the entertainment was same vintage: screen was not very bright and the selection of films was poor. No plug to charge electronics. We were disappointed with KLM when comparing with other airline companies offerings when you book in Premium Economy.

Good 6.0

Pros: The crew were personable and the chocolate that was offered near the end of the flight was a nice touch.

Cons: Cramped, cramped, cramped!!!!! The seat pitch was just so uncomfortably short so much so that when the person in front of me reclined his seat, the TV screen was a mere 1-2 feet away from my face making it impossible to watch anything without getting crossed eyed or a headache. This unfortunate situation has influenced this review greatly particularly because this wasn’t a 2 hour flight but a long haul one.

Excellent 9.3

Pros: Friendly agents . Speak very good English. Swiss airlines serves breakfast croissants and beverages for a short flight without a charge

Cons: The airline fix the booking problem because my trip was from Zurich to Brussels to Washington DC to Austin and went I print my boarding passes only show to Brussels. The booking agent didn’t complete all the way in the computer. I am thankful that I had my original paper and Swiss airlines fix it

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,
