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.

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.

Flight was on time, staff are friendly and helpful onboard.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

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!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

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 did not like I have been charged for my carry on

Onward flight was okay. return from Lisbon was poor as we missed our flight due to a long line at the passport control. Air Transat made no effort to accommodate us even though we were at the passport control 40 minutes prior to the departure.

Very good. A lot better experience then I expected for an economy flight.

It was very good but no tv but the experience was great

Thank you for making my first experience very enjoyable. You made it all very pleasant

Great flight great seats will absolutely fly with you again

Porter airlines was good. I didn't have the best experience when booking through airfare assist however, as I got no final confirmation from them that the flight was booked until I called them. Even then, the confirmation code they gave me was incorrect and couldn't be used for check in. On a positive note airfare assist was actually picked up the phone relatively quickly when calling

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

Everything was horrible. On the day of my departure, I was denied check-in and boarding because my reservation only showed one of my last names, while my passport contains both. This minor discrepancy could have been easily corrected, but I was informed that no adjustment could be made. As a result, I lost not only my outbound flight but also my return flight and had to purchase a new ticket at a significantly higher cost.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Missed flight. Requested assistance for my father and he did not receive it in Paris.

Business Class was very comfortable and the food and service was top notch.

The crew was very nice. The equipment on the 747 felt old.

As expected. Would have appreciated a 3-day headsup reminder as a reassurance that all is well.

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded

The plane was late (as was my flight out from Birmingham the day before)

Business Class Configuration was excellent- private and comfortable. Crew and service were excellent. I really appreciate Air Canada cabin pressurization equal to an altitude of 8,000ft. Upon landing, I felt more alert and refreshed than typical for international flights

Hard to use tables and TV screens interfere with the enjoyment of flight experience. Other than that it was a smooth and comfortable ride and we were well taken care of.

Excellent flight overall. Lufthansa Business service was excellent with great cabin crew and very good food and wines. The seat comfort was excellent. Only a slight reduction in score due to the 747-400 being a relatively loud aircraft these days.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

Entertainment devices on A380 need to be fixed, the seats might do with updates.

I like everything about British Airways. Excellence. Perfect. Exquisite service.

The plane was dirty the food was awful and the boarding process took too long

Everything. Employees offered to help me because I had to use a cane.
