The flight was 45 mins late leaving, we sat without a/c for some of this, 2nd Meal was a slice of pizza. Movies were good.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

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

The baggage service at Malpensa was the worst ever. We wanted for over an hour without any information, they broke my suitcase, and the services of the local luggage services company was below any usual services level of a KLM partner.

The flight was great, the only reason for middle scores on entertainment and food is that it was a short flight so not included (but snacks were served including alcoholic beverages free of charge). I would definitely recommend KLM.

Was trying to change a flight but told that Canadian and local klm systems do not interact so they could not access my booking. Overall I like klm a lot but if it was important to change flights I would be very frustrated.

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

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!

I travel frequently. The flight was late again... KLM should really try and be on time

All and all pretty good. It’s crowded but that is what flying is all about. But no complaints otherwise.

Very unprofessional treatment of customers - boardring on being unethical. Only cares about money and not the customer. If you use the swiss brand, you should deserve it - now swiss air doesn't deserve the swiss brand.

Made us gate check carry ons Then didn’t get them on the plane. Service they used didn’t deliver our carry ons for more than a day Total mess

Best international flight I have had in a while! Far superior accommodation, services, food and general experience compared to U.S. airline companies.

They didn't give us Nothing to eat, come on..... 1 package of chips and a glass of soda won't do anything to the company

Flight was diverted from Firenze to Pisa causing delay and inconvenience.

Checked me out of my connecting flight despite having enough time to transfer, had to check in again at the gate. Then they lost my luggage.

The pilot was wonderful and enthusiastic and introduced himself over the intercom. We all felt in good hands. Crew were all super friendly and especially the young , gentleman crew member. Everything Swiss airlines represents. Hospitality, friendly and professional. Thank you. Truly a memorable short flight.

Swiss ground crew was again at its prime and although I’m United 1K (Star Alliance Gold) they created problems with my hand luggage - while other passengers were boarding with more handbags and larger hand luggages, were critical on my 2 young kids attending the lounge with me and boarding the plane with me on the priority lane.

We so appreciated that our connecting flight waited for 6 of us!!!

A lot of things could have been better. They lost our luggage. We missed our connection from YVR to Naples when we arrived in Zurich and then we got re-routed to Rome and then Naples. We eventually got to Naples but our bags didn’t. Our experience at the lost luggage in the Naples was not at all reassuring. They didn’t seem that interested in our problem. I did a live chat with Swiss customer service and all they could do is tell me to follow the process. Meanwhile we’ve had to spend significant money on clothes and I have to replace medications. This has meant our trip so far has been totally different than what we had planned. It’s not clear that our baggage will ever show up which means we will have lost significant amount of clothing and other things and our two month trip to Europe will have more problems than good memories. So far we are not happy.

To complex. So many types of fare. This made the boarding a caos.

Good standard flight the plan was clean could not complain the only thing is checking in the pushchair was very slow only 3 people at the counter.

The flight was delayed and nobody was able to inform me about the new scheduled time and gate

Non stop flight from Barcelona to Rome, arriving on time.

Boarding was very poor as the flight was initially delayed. We were told the flight would be at 21:40. We were with our 10 month baby who was sleeping. I received an email from Kayak which said the flight was now due to take off at 21:04. When we checked the screens at Gatwick we were told the gate was closed. The lack of communication was extremely poor and we had to run with our baby and there were many other passengers, including elderly people, also running to the gate. When we got to the gate, the staff had no reasons for the poor communication.

We got to the airport 2 hours before the flight. We waited in a line to check our bags onto the flight for an hour, even despite having checked in online, as there weren't enough self check terminals allocated to Vueling (yet loads of empty BA ones right next to them). There also weren't enough staff, making them stressed and rude. We had to try and rush through security to get to our gate, which they announced as gate 35 at first and then changed it after ten minutes with no announcement to anyone in the airport that it had changed. So we then had to rush to the correct gate to arrive just as boarding started. It was a thoroughly stressful process and one travelling couple almost missed boarding because of it. The flight boarding and the flight itself werre fine, the staff were polite, but I was dehydrated due to the airport and had to buy a bottle of water as they didn't offer free drinks.

You have couple of KG's grace on checked luggage

I liked the regular updates and appreciated the automatic online checkin which didn’t work for our Vueling flight so I had to do this myself.

The baggage policy is pathetic. We paid for our carry-on bags online. Said if we don't remove the wheels of our carry-ons it's not considered a carry-on. We all measured our bags according to the website beforehand. We were not refunded for our bags and were obligated to buy it as checked in bags for over $70 online or $90 over the counter. First and last time I travel with this airline.

We were very lucky and got a complementary upgrade somehow because the crew needed our seats.

Never made it to Lufthansa because of Air Canadas negligence.

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

There is more space in this economy seat. It felt like a better layout, not so cramped.

The staff was not at pleasant as those on the first leg of our trip.

Crew was excellent. Sat us together after the airline changed our seats. This was the smaller plane/shorter flight so no entertainment or food.

Boarding was one hour late. Gate notification was incorrect (notification said gate 17, actual was gate 14). Took shuttle bus to board the plane. Late arrival of plane at Turin impacted travel arrangements to the event.

They canceled our flight right before it was to take off and then we stood in line for four hours to make other arrangements. It completely ruined our trip.

Flight boarding was delayed. Old, low capacity overhead bins requiring many to gate check their carry-on luggage. Beverages other than water were at a charge.

My baggage has been lost for the last 6 days! The problem originated at LAX with Lufthansa, which was a very big disappointment from LAX to Munich. The flight was delayed over an hour, the overhead bins on the window side are too small for most carryon's, the in-seat video screen were very poor as they would not respond to your touch quickly and would stop and start all over again, the earphone jacks are not like most standard ones, the seats still has wrappers and trash in pockets and on the seats. and there was no USB outlet to charge your phone or other devices. The German reputation for quality is bogus with this airline. BUT the responsibility for delivering my luggage became Air Dolomiti's as they were the last leg of the trip. The baggage area was chaos because several flights arrived at once. I took me over an hour to file a claim, the agent entered my info incorrectly, and the contact numbers for Lost and Found at the airport was never answered. I have never been called by Air Dolomiti or the baggage delivery company. I had to do all the calling. AD's live agents gave me two wrong phone numbers for the baggage company. When I finally got the right one on my third call, OF COURSE, no one answers and I still do not have any information on when my bags should arrive. VERY UNPROFESSIONAL operations by Lufthansa and Air Dolomiti. I will make sure I book any other air carriers on the rest of my flights to Italy this year.

The crew and flight was fine and enjoyable…unfortunately, when I arrived to Bari and received my checked luggage(that I bought for this first trip to Europe), one of bags had a huge dent in it and the other had a completely damaged/broken wheel that made it very difficult to travel the rest of my time in Italy. Very disappointing and frustrating!

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

The space is tight. Either you sit straight up the whole time, but the minute you relax, your knees hit the back of the seat in front of you. My seat would not recline so I was quite uncomfortable. Didn’t use my tray table bc it was stained and sticky and nasty. I was also seating in one of the last rows and one crew member and people going to the bathroom kept hitting my elbow resting on the armrest.

Boarding market okay just because of the delay we had, but not related to the crew in any way…

charging port did not work, no entertainment system. Other than that the flight was good and safe.

Not the quality I was expecting from a company that has been around for ages and charges high prices

Very quick boarding. I was surprised we only got a small water and small thing of cookies, everything else was for purchase. No entertainment. Crew was excellent though.

After boarding, take off delayed 45 minutes with us just sitting there. I think this a Heathrow problem

Every part of the flight from PHL - LHR was perfect in every way!
