Crew was courteous and polite! Entertainment system had some great movies at no additional cost.

Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?

The cabin crew was nice. The main dish was good. The entertainment choices were decent and the system worked fine. I don't sleep in planes so it's important to me. I got a forward facing seat so at least I didn't have to deal with the alternative.

Not being able to make seat assignment earlier (i.e. 24h) was lame for a business flight. The second meal was mediocre, as was coffee. The screen of my entertainment system was scratched and cracked, but it didn't disturb me too much.

British Airways provides complimentary amenities in coach not found on US carriers: A hot meal, snacks, beverages other than water or coffee/tea. Their media selection is superb. They seem to work hard to make a nine-hour flight over The Pond as tolerable as possible.

My comfort was better on the return leg because I had the extra leg room that comes with being seated on the emergency exit row. However, regular coach seating is at best tolerable. You are packed like sardines and the seats are firm, to put it mildly.

Seats 23A, 23B were extra cramped on the B777-300ER, even though they are sold as "extra comfort"! due to the video screen taking space between the seats. The seats were so cramped that the overhead light kept coming on, unknowingly, when people shifted in their seats.

The overhead bin did not stay down low enough so that I could place my bag in. It would lower then before I could place my bag raise slightly by a few inches. For someone of my height (5’5”) that was problematic. Fortunately another passenger saw my dilemma and held the bin lower to its full opening capacity. This also momentarily slowed down the boarding process.

The outbound crew was terrific. The flight itself was fine. We even arrived early.

Upon deplaning in Cancun, ALL passengers are put on a bus and driven far away from the terminals to an arrivals area. Those of us with connecting flights are royally f*cked at that point, especially if your connection is short, as mine was. The so-called shuttle to the departure terminals, which are entire kilometers away, was to arrive in like half an hour. HALF AN HOUR. Who has this time to spare?? The alternative to the shuttle is paying a taxi that charges a hefty fare--and God help you if you don't have cash. The departures terminal was swamped and only thru begging assistance and line cuts did I make my connection...and then only by the skin of my teeth. It was a complete nightmare.

Hard to say what I liked as my experience was soured right from the onset

I was surprised by being charged almost $100 to check in my luggage, and over $100 on my return leg. (Yes! I could have looked at their baggage policy, but there was no glaring notification alerting me to this fact when I purchased the ticket, nor when I was checking in online) Then, I was further surprised that you had to pay for food on board. This was a first. I mean, on an international long distance flight? Everything became mediocre after these, and I mentally swore off flying this airline ever again.

Was over an hour late to board and depart. Missed connection in Seattle, was then given printed paperwork for new flight which would not get us through security and then had to go back to main desk, almost missing connecting flight for the 2nd time. Little to no communication as to why we were delayed. Very little help from flight crew as to what our options were since connection was missed etc.

Primer experiencia en KLM y no pienso nunca más usar esta aerolínea. Llevar el equipaje o resolver un problema sobre valijas es de lo más básico de una aerolínea y no lo hacen.

Ground staff at Manchester very helpful

Information on KLM website and flight status said 50 minutes delay and was never updated with the true status. 3 hours before we took off. KLM blamed the fog at Manchester but to be honest most other flights seemed unaffected. Put up in an IBIS hotel and fed substandard food and shitty hotel room with an Aircon unit that clunks into action every 30 seconds keeping me awake. It's external so I can't switch it off. Being given a 10 Euro voucher for food at the airport when most food and a drink will cost you 12 to 15 euros.

This was in coach class, so I understand the cramped quarters, but even on a long haul flight (BA 49, LHR-SEA), how could they justify the seating in the planes? Perhaps BA executives should fly coach class on one of these planes to understand what they are putting their customers up to. Here are 2 additional items that should be a no-brainer to fix: a) They ran out of fresh bottled water. For the last one hour, all they could offer was sparkling water b) Somehow BA seem to be saving on food portions (or their caterer needs to be changed) - lunch/dinner portions are way too small.

The Lufthansa crew is always wonderful as always.

screaming and kicking child behind my seat, with no way to "escape". I had a severe cold and that was certainly not something I needed, I tried to get some rest, but that was impossible. The seats are getting smaller and smaller, hardly any legroom whatsoever. Also, what I had planned on bringing on the aircraft as carry on (which was my work equipment, tablet/printer etc), I had to check in as luggage because it was "overweight" meaning more than 8 kg and pay ADDITIONAL $200 (in addition to the $100 I already paid for one suitcase). I've seen many passengers with "heavy" carry on, which they were apparently allowed to bring into the cabin without any problems. I had never had to pay for any carry on, and I am seriously considering using another airline for future business travel.

The flight attendants could not do enough for you.

Business class was pretty empty but again I was not allowed to change my seat selection online. Pathetic check-in.

una valija se perdió. Eso desató el descontrol que tiene KLM para seguir el equipaje. No hay como hacer tracking. No hay un teléfono a donde hablar, la web está desactualizada y con información equivocada. Direccionan a usar canales de twitter y facebook que no responden. Primer experiencia en KLM y no pienso nunca más usar esta aerolínea. Llevar el equipaje o resolver un problema sobre valijas es de lo más básico de una aerolínea y no lo hacen.

Entertainment was good, and crew was very nice and accommodating. Flight was very comfortable and smooth.

The food was okay, not that great.

Ground staff at Manchester very helpful

Information on KLM website and flight status said 50 minutes delay and was never updated with the true status. 3 hours before we took off. KLM blamed the fog at Manchester but to be honest most other flights seemed unaffected. Put up in an IBIS hotel and fed substandard food and shitty hotel room with an Aircon unit that clunks into action every 30 seconds keeping me awake. It's external so I can't switch it off. Being given a 10 Euro voucher for food at the airport when most food and a drink will cost you 12 to 15 euros.

They were very good about keeping the lights down as much as possible on this red eye flight. Announcements were also kept to a minimum. The re were comfy blankets, pillows, and water waiting for us on every seat.

The seats are not that comfortable - seems they skimped on padding, plus my seat wouldn’t stay reclined and my husbands wouldn’t recline at all. The space under the seats in front of us was very restricted: there is only space for a bag or for feet, not both.

The aircraft, crew, and entertainment were excellent. We knew that food was available for sale so we prepared a picnic lunch. All of the usual soft drinks were complementary. Boarding was organized and timely at both locations.

Cold weather and snow on Iceland meant that all aircraft needed to be de iced which took up some time. That is not the fault of the airline.

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,
