The baggage belt was not updated on the Delta App and was displayed on the wrong belt board. Was not expecting this to happen.

The baggage belt was not updated on the Delta App and was displayed on the wrong belt board. Was not expecting this to happen.

The tray table was broken and the food was terrible.

The flight was smooth, the crew was great but the plane was quite old

The boarding was organized and informative but the plane was tight meaning that you were sitting on one another and extremely uncomfortable. It’s disappointing that can’t have common seating comfort on the plane.

I love Delta the flight attendants were personable and the flight arrived 1/2 earlier thanks expected. All a plus. The gate agent was a bit flustered but even with that I still had a good experience. Her supervisor assisted me.

Wonderful crew, great movie selection and good food. I prefer Airbus to Boeing, much more comfortable

I wish the inflight entertainment system options were broader, but overall this was a fantastic crew and I can’t express how cheerful, welcoming, and attentive they were.

Delayed. Hot. Passenger next to me was so large I couldn’t move.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

There were no charge points for phones on the economy seats. The seats were comfortable overall. Food was okay.. flight was on time

It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

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.

Terrible last row seats many seats available but no offer to move to better seat

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

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 flight didn’t happen because they apparently lost my check in and wouldn’t let me board.

I wasn’t checked in for the third leg of my flight, my bag was checked through to Dublin but when I went to the gate in Toronto they said I wasn’t on the flight and had given my seat away. I had to wait 24 hours for another flight and instead on the one I had booked it was now 2 flights.

Flight was delayed by 3/4 of an hour. Overall flight was good.

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

Waited at airport from 10 am till 4 pm and no flight due to fog. Ugh.

Plane was one hour late. Hardly any space for our carry-ons. Stressful to catch connections.

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

Overall service is good. Just thought foods need to upgrade for economy class

No communication from Kayak or West Jet. Booked extra flights, flights cancelled, no one answers calls. Will be disputing charges.

Leg room is a problem the plane was dirty and there were no movies available on the app

We travelled from London to Halifax. Customer service was excellent.fron the day we booked until arriving. The gate was only a short frombthe waiting area and walk Boarding was efficiently handled and plane took off on time. The service on the plane was very good. Fool an acceptable drandard Only downside was that the legroom was tight for anybody just over 6ft tall and am usually able to travel without difficulty. I will definitely fly with Air Canada again but next time pay for extr space.

Was disappointed when landing in Canada was made to wait for over 1 hour with several other parents and babies for our strollers . The expectation was that the gate checked strollers would be there when exiting aircraft. This was not the case we were told to walk to a point and wait for them . After being left there and not being updated we were met with very hostile and rude air canada staff . There where no apologies or understanding even though all the children where very uncomfortable and the parents very frustrated as you can imagine . Instead the air canada staff at the airport where very rude and made an already frustrating situation much worse instead of trying to assure the parents that that were making effort to fix the situation. One gentleman in particular was very rude to some parents telling them to move when they were simply seeking information. He made the other parents including myself feel very uncomfortable. He also told a gentleman he was capturing images of everyones boarding pass when this was untrue as he was only taking a photo of the gentleman pass which was strange.

Our original flight was cancelled due to mechanical reasons. This cancellation caused us to miss our connection and we were not able to get another flight for 3 days and then needed to make an extra connection to get there. Air Canada did not rebook our flight for us, it took several hours of talking with staff in the airport and making phone calls to get the flights rebooked. We never received a voucher for our hotel and meals while we were waiting for our next flight and it was only after talking to several staff that we were provided some general information about how we could be reimbursed. We tried entering our ticket information in the website provided, but it did not recognize our flight information. When we asked someone on the phone about this they said we'd need to contact the customer relations department, but that it's not possible to reach them on the phone. I don't understand what company would have a customer relations department that you can't talk to. We spent about $1,000 for hotels and meals for our family while waiting for a flight home and I'm not confident we will ever get reimbursed for this. I understand that mechanical issues can happen to any airline, but this is the 4th time that this has happened to my wife and I on Air Canada and we have only flown Air Canada about 8 times, so this is not a good track record. Also, when we did finally get a flight home (which was also delayed due to mechanical problems), we were told we couldn't bring a standard carry on even though the information on our ticket clearly indicated that we could bring a carry on bag. The staff at the gate were not understanding about this situation.

It was good, seating was a little tight apart from that all was well.

I liked the flight but the check in was horrendous. I have booked with you before but not ever had to pay extra for luggage, it was not clear on booking, I didn't know there was different categories of economy that meant different allowances. So was alarmed when we had to pay a further £120 at the check-in at a point of not changing.

We were happy with the service and cost of checking a bag

I wish they gave the earphones earlier rather than when we are already in flight.

Very nice staff members are very nice and friendly helpful

The internet connection was perfect, and the updated entertainment systems that allow me to connect my Bluetooth earbuds was excellent

It was good to receive a card for my birthday

The flight was delayed 7 hours and we were given 10 euros vouchers. This is ridiculous. The crew was not nice at all, they just did their job with serving food and drinks. Did not even apologize for the delay!!!!

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

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
