Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

You should not have to pay for WiFi in business class

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

Weeeeeeell, you folks know economy class on Airbuses well--you're packed in like sardines. We may actually spring for more expensive seats next time, with a little room to stretch out. NO room to stretch out in Airbus economy class! :-) Apart from this, the food was decent (considering that it's mass-produced, and has severe spatial restrictions of its own), the staff were friendly enough, and there was a wide selection of movies, etc. to watch. Overall, I'd tend to use the word "adequate" rather than "exceptional" for my experience. But really, how could it be otherwise?

Excellent service, full flight but all went well ; slightly delayed start at Faro but arrived in Cork on time.

The ease of boarding was good. I wish they had something to eat on the plane.

The check in process at CDG was absolutely unacceptable. We arrived to the airport 3 hours and 20 minutes before our departure time, waited in line for 1 hour and 30 minutes to check in (despite having checked in online and only needing to check a bag), then were forced to check all of our rolling luggage despite the fact that all were compliant with carry-on requirements. The staff at the desk were rude and there were only two desks open, while eight people were working. The check in desk wasn’t even opened on time (3 hours prior to departure) and there was no communication about when it would open or why there was a delay. We feared missing our flight because the departure board was not updated, so rushed to our gate to board once we were through security because it was 20 minutes prior to departure, only to wait another 30 minutes before boarding even started. Communication was lacking throughout the process. What a horrible end to our trip.

Seats were less comfortable and tight from Newark to Dublin, than my second flight ( small segment from Dublin to Lyon). Movie audio was with frying sound overall. Yet the worst was as follows: one male, (dark hair , glasses on) from the crew member was so cold and rough, while I remained with constancy polite and kind. Per exple with the noise level I could not hear him at first for beverages, he rolled his eyes at the third times I finally heard him. From the start, loading my small hand bags , he directly spoke to me and said “ I had to keep my shopping bad by my seat, under , while there was sufficient room and I was among the last to sit. I show him the space , his face was always dull, stoic, not welcoming as the usual crew members from any airline companies are. When I think of my experience I liard w Aer Lingus, this is the image that gets back to me. Needless to say that as a passenger and client, I felt belittled since all this happened in front of the surrendering passengers. It s an affront and not a pleasant feeling especially when being traveling which oftentimes involves stress with carrying, and making it on time. I m not happy with the experience I had to be honest and I fly four times a year. Thank you for allowing me to share this statement with your company.

Really helpful staff at the airport and the flight was comfortable with good entertainment options and food service

The flight was delayed by about an hour, but the staff and signs at the airport never actually said it was delayed. At the expected boarding time, we were told we would be boarding in about 10 minutes, then 20 minutes passed, and were told again that we would board in about 10 minutes. That happened multiple times, such that "10 minutes" turned into an hour.

It was fine. We were delayed leaving but a situation of too many planes, not the airlines fault.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.

I couldn’t understand the aircraft tannoy announcements I was in seat 20C - nobody in our row could either. Speakers a bit too quiet plus messages read out too fast. Otherwise excellent flight. (Flight delayed by 50 mins)

I bought my flight, insurance etc early and paid over £200. But had i waited until closer the time the price was much cheaper, i appreciate that it could've been more expensive but it wasn't. A better discount for booking early would be better than your current one

ontime and super quick boarding and disembarking. I made it in 6 min from airplane through passport control to the train platformin Cologne. Amazingly quick airport.

There plane had a technical pricken so we had to disembark, but the replacement aircraft was provided within one hour so there was not much delay.

Miserable staff did not want to be there. Very poor atmosphere boarding. Then just basic flight.
