I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

The cancellation was disappointing but the arrangement afterwards was prompt and efficient. The seats arrangement were good. I still need to read further the details of how to get the compensation. All the flights taken were 100% delayed, not to mention the one that was cancelled. I couldn't sleep much in the flight from Abu Dhabi to Hong Kong because the egornomic design of the seat is not very comfy. Although there is more leg room, the seat itself was too tight and too hard. I suppose it would be the design of the seat that needs further improvements. The service of the crew and the boarding was good. The food on the flight from Amsterdam to Abu Dhabi was better maybe because the flight was in the morning, the food feels much fresher to the palate. And it was tastier.

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Klm start boarding while somw air issue in the plan

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

Overall a very pleasant flight. No significant issues on either flight. Amsterdam airport is very convenient for connecting

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

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.

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

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

Business class should have free wi-fi. Food was horrible

Short comfortable flight. Like many European and US based airlines - expect a budget airline experience even on full service airlines

uneventful, good economy section, friendly staffs, good food, safe flight.

More leg room than I expected, comfy seats, complimentary soft drinks when requested.

The seats are very uncomfortable. They never have tomato juice. Usually late

Finnair was not able to get our luggage on a connecting flight and there was a substantial delay of two days to obtain our lugguage. They did not communicate well, and we had to travel a significant distance to finally get our luggage. It has been a very negative experience.

On a more than 8 hours flight was only one meal included, which I have never experienced before. Always two meals on the overseas flight. It was very weird.

Business seating is soooo uncomfortable. You can sit straight up or lay down. You need pillows behind you because the back doesn’t lay down. Those are need to “prop” you up. The chair has no padding whatsoever. Food was gross. I’ve eaten on Finnair before and the food was exceptional. This time it gave 2 people in our party diarrhea. It was the chicken dish. I took 2 bites and didn’t eat anything more. The flight attendants were nice. You needed an additional lounge in Terminal D at DFW Airport. After waiting 40 minutes to enter, we finally gave up and went to a bar across from the club doors. I’m unsure if I’ll ever book a Finnair flight again.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

The leg room in economy was sub par, everything else was fine.

I was on SAS, not AeroMexico. How the great have fallen. I used to revere SAS-no more. First off, I was charged a $150 for two checked bags (that's almost twice what the bottom-feeder American Airlines charges). Talk about predatory. The aircraft was a crappy Boeing 757, with a seat pitch tighter than a cut-rate airline like United or Frontier. That was one uncomfortable seat, not leather, but rough cloth. Most of all irritation, no soda or snack on a four hour trip. Wow, cheapskate cut-rate airline. They used to be very comfortable and generous, but that was a decade ago. Never again, that's for sure. The crew was friendly and professional ad they did get there on-time - the only positive aspect of this experience.

Elderly traveler with disability was bumped from extra legroom to economy with little legroom. He couldn’t bend his knee to fit in the seat. Very uncomfortable for a 7 hour flight and will be reported to DOT. Then the food was disgusting. Boiled chicken with boiled rice and steamed veggies. 3 slices of carrot and one broccoli. We couldn’t eat it. No salt or pepper provided. Disgusting.

Probably not much to expect from a European domestic flight but it helps if they check the airplane for safe travel before boarding people. We had to stay on the tarmac and go back to gate for some sensor malfunction and refueling for two hours.

It was ok but no WiFi I think I’ll fly Iceland air next time

This is my fifth time flying with SAS and I love it

Food was underwhelming. One free coke, charged $$ for one wine. Last year one wine was included. And prices were much lower.

Flight was canceled and the crew on the ground/front desk were I’ll equipped to handle. One woman was left to handle 150 passengers while her colleagues stood there saying: just 5 more minutes repeatedly.

All was good. I think the back of the plane should be boarded first. It would be faster. Minimal waiting time behind passengers loading their carry on baggage.

It didn't happen. SAS csncrlled and it was very difficult to convince the 3rd party they did. Not good on the 3rd party program. I don't think they trust their customers, much less being able to help them. I have had several nitemaes using 3rd party this trip and WILL NEVER use 3rd party again.
