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.

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

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.

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

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

The male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not a good one this time. The absence of internet without any information/notification ahead was really the unacceptable part. Also this new A350-900 has a serious legroom challenge for economy seats. It’s more like a medium-haul flight legroom configuration.

Food and flight attendents with positive dispositions and friendly behavior, more professional attitudes

Compared with other carriers business class for an overnight was not worth the extra expense.

Well, this is my second flight from THE first one that I took and this one was from Manila to Guam. The flight was comfortable. I did end up in first class. However, I had to fight for it a little bit, but when I went to Guam, I had to stay an extra night there, which was accommodated by united Which I'm pleased for that. The only thing that I have to say is when a situation happens with a cancelation. And you got first class guests very important that you accommodate and make sure that they have their flights before everybody else does, because we pay big money for the service and it is not cheap also. Take note There are things that we have planned as well. So this kind of damaged the tail end of my vacation, which I lost out in $2500 worth of car rentals hotel fair in Honolulu, Hawaii. I'm really hoping that I can be reimbursed at least that money from the insurance that I have on the trip through united. I will be submitting that in as well. When I'm back in the United States, because I'm currently in Guam. Staying good night. I'm waiting for my next flight out. For tomorrow morning..

Average. Newark is a United Hub, yet a flight that is early somehow ends up getting late to the gate. Newark ATC needs help badly.

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

Cabin crew was very friendly, requests were satisfied promptly and cheerfully, and the cabin was reasonably clean when I boarded. The United lounges at Newark and Heathrow are always well-run and comfortable, especially Newark. I look forward to the new lounge that will be part of the rebuild of Terminal 2 at Heathrow.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

Had a crying baby and a toddler behind me so it was difficult to get comfortable. Searing was tight even for a relatively small person like myself (5’8” 155). Fast flight but arrived so early the gate assigned was still occupied by another plane so we had to wait for about 20-25 minutes to get reassigned to a new gate and get over there.

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

The senior flight attendants were amazing. Totally different vibe from other carriers. Easy 10 hour flight in Business Class. Great food. Good humor as well.

an absolute disaster and nightmare on air condition. IT WAS FREEZING!! everyone around us had hats, hoodies, gloves outdoor jackets on. that segment of the aircraft had a fault I assume...no amount of suggestion to turn down the air con helped. otherwise all good.

Everything was very good, short delay Toronto to Regina on my return to Canada but not a big deal. Thanks Kayak, Dr. Ian Stewart

Boarded smoothly, took off on time. Entertainment screens were reliable and the movie library is abundant. Food better than wtst was served on the first leg of the journey by another airline.

every single person involved showed their joy, working in the airline industry - it created a very pleasant atmosphere for everyone

The seats can always be bigger and have more leg room.

Check in was incredibly fast, fukuoka was comfortable and crew very pleasant. The only negative was that the boarding was somewhat chaotic, but it so often is these days as airlines tend to board by how much you pay and not by what an orderly process of filling the plane would be.

It was ok. Even after the airport bus took us to the terminal , we did not expect to walk 35 mins inside the airport to the gate . A 15 min walk is ok . Especially if there was any delay in TSA check which happens to is too then people can easily miss the flight.

Excellent bit seats are still a little too small and there's that $75 baggage charge.

Very disappointed with how we left Heathrow, and the service from Air Canada. When food was given, I was skipped by the attendant, and when I went to tell him, he just dropped the tray of food on my table. Leaving Heathrow and landing in Montreal were bad, which is not Air Canada’s fault, but the service itself was not good.

For boarding, after family with youngsters, you should have 65 and over. Whatever rules, enforce them. It’s frustrating for those who respect them to see aggressive people rush to the gate out of turn…

The flight was delayed by an hour. Made the connection uncomfortably tight.

The airport crew and flight crew did a great job rearranging the gate at the last minute and got us to Munich on time

I enjoyed my flight back with Lufthansa because the food was good, and the flight attendants were nice and helped you when you asked a question. The flight attendants always came around and asked if you needed anything which I liked a lot.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Pretty poor across the board - flight details wrong/delayed into Lufthansa app. Seat changes made without notification. Boarding delayed (ok, that happens) but all comms in German (for flight to UK, where 85% of passengers were English). Outright fraud attempted at gate, denying 1 piece carry-on of smaller than correct size and 1 piece personal item, again, smaller than correct size. Rude gate staff. Security checks perfunctory - unattended bag not acknowledged by staff..then put on aircraft unclaimed by staff.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

The flight was delayed and I was stressing the whole time about whether I would make my next flight.

Service was okay. Food was okay. I selected a window seat in the 36th row and someone took it upon themself to change it to an aisle seat in the very last row!!!

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.
