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.

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

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 .

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

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

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.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

Flight delayed over an hour. They said they would hold our connection but then did not.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

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

Ancient aircraft (busted armrests, poor cabin temperature with no option for passenger control). Garbage everywhere. Risible checking of safely conditions on landing. Also, late.

Excellent service throughout. Airport process is quick and easy. Very courteous staff. Great service in the plane! Just outstanding punctuality and service overall!!

It was a fairly old plane in which you couldn't buy an internet connection.

I love it the scandavians know hospitality travel and are very friendly peopu

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.
