Flight was delayed. Can happen. But the info on the website and app said that flight was cancelled which was not the case.

Flight was delayed. Can happen. But the info on the website and app said that flight was cancelled which was not the case.

The whole trip was excellent. The only thing I would change is the temperature of the plane was a bit high which made it uncomfortable to sleep.

KLM is my favourite airline. Never ever let us down.Staff are first class.

Put some new and several options for entertainment. Do not be rude to customers and avoid serving them an extra coke or something. We paid 1200 GBP for a return flight.. A noisy, crowded, rude and uncomfortable flight.

Pretty bad. Food was awful. drinks were scarce, as if drinking an extra drink would ruin the airline. attendants were not very helpful. likely Dutch "directedness" (I cannot be bothered). Crammed flight. Entertainment in very minimal dosage. Almost all old movies and series with 1-3 episodes only. Very limited number of options available. Jesus!! it seems you need to bring your own entertainment these days even of flights that are 13 hrs long!! I would and I will avoid in the future!

Quick and efficient as always. Air France managed to loose and damage my luggage that never made it onto my KLM flight.

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

They lost my baggage and I still have not got it back. Disgrace

They lost my lauggage and I STILL HAVE NOT RECEIVED IT. NO ONE IS HELPING! PLEASE HELP FIND MY LOST LAUGGAGE

They again did not offer any functioning WiFi in the transatlantic crossing.

At check-in at Guarulhos Airport, I was coerced to pay EUROS 100 for each of my two teenage kids travelling on economy premium on the same flight (total charge of EUROS 200) to AIR FRANCE on the rational that they were on a different class and therefore they would require additional care from the flight crew. My wife and I would be (and actually flew) only a few meters from our kids on business class in the same flight. Air France took EUROS 200 from me in exchange for absolutely nothing. My kids are seasoned travelers and independent, and in any event, they were not given any special or any other assistance or attention by Air France flight crew as result or in connection with the fee charged from me at any given time during the flight to Paris - so ABSOLUTELY NO SERVICE WAS PERFORMED AND THE FEE WAS SIMPLY ANOTHER WAY OF “MILKING “ EXTRA EUROS 200 FROM ME. Worse, Air France made us wait for everyone to deplane in Paris to let us deplane - after an Air France Paris representative ridiculously confirmed that our kids were our kids, with our kids at that time already by our side seating in business class. We almost lost our connection to Malta as a result. Such a scheme from Air France is outrageous – especially because it penalizes its customers flying in business class or in first class. I would have imagined that Air France would have wanted to attract clients to fly its premium classes – not to charge cheap EURO 100 fees and to keep them waiting to deplane with their families after 12 hours flights at their destination. You won’t see us any time soon Air France and best of luck with your strategy !

Flight was late over a hour just like the first one. WiFi was down.

I paid 3 this and dollars for two tickets. No food, minimum drink, confused service and very uncomfortable sear. There was zero difference between busy ness and tourist class. I received a pathetic apology

Good. Food items are ok but not really healthy (no protein for the vegetarian option, just a total of 2 gr total) so not fulfilling. Also, no airline is educating passengers to behave and have common sense: let the one sitting by the window pass first, leave toilets clean after use, etc. Humanity is just getting rude and more disgusting by the day and without education or enforced common sense no

Old cabine without flat bed in business for a 12 hour flight is not acceptable

Generally good. The crew is excellent. The food could be better.

Excellent apart from transport to actual plane 10 minutes from the actual gate , walking out in the tarmac in the rain and having to climb stairs to enter while holding luggage.

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

i didnt go this was a hacker booked this flight on my debit card !

Delayed almost 2 hours sitting on plane. No updates at all from flight deck and virtually no updates from cabin crew

Be sure to check bags for 23 kg,.(50 lbs) Coming from US I chose the wrong size luggage weight when I checked in on my phone, and had to pay more when I dropped it off

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

They cancelled my flight and we had to fend for ourselves to reschedule another flight. There was no staff to help all the canceled guest. Poor communication and staff. I attempted to reschedule via Kayak and I asked their staff that it looked as it was available. The guy behind the counter just told us to go online..

Worst airline in the world, will never travel in it again.

Well Is extra charge for everything and other companies include that and the price.

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Flight delayed a bit. Boarding by seat row number in two parts. Flight attendants weren’t greeting boarders, they were talking to each other. In the outward journey much the same yesterday and that was a different crew to a different airport. I do get the feeling on Blue Island Flights that they have no interest in even allowing passengers to use the toilet . The flights are short but in fact they keep the seatbelt sign on for the duration.

Basic economy flight, random seating unless you pay extra, no refreshments, friendly and attentive crew, slightly late boarding and taking off. 40 minutes max all in

As someone who has limited mobility it was appreciated that the staff took particular care to ensure that my needs were catered for with priority boarding and assistance both on and off the plane.

Cons: "Delayed for 2 hours due to “fleet issues”, no food or water on board due to “weight restrictions”"
