I love Air France. This was another great experience despite a slight delay in the departure. The time was made up on flight. I would take AirFrance again when traveling to the far East. Merci beaucoup.

I love Air France. This was another great experience despite a slight delay in the departure. The time was made up on flight. I would take AirFrance again when traveling to the far East. Merci beaucoup.

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.

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.

Forty five minutes late for departure. Staff were pleasant. Food was adequate but not outstanding. Entertainment system was very good, as it usually is on Air France.

Good. Food items are ok but not really healthy (no protein for the vegetarian option, just a total of 2 gr total) so not fulfilling. Also, no airline is educating passengers to behave and have common sense: let the one sitting by the window pass first, leave toilets clean after use, etc. Humanity is just getting rude and more disgusting by the day and without education or enforced common sense no

Did not find the wheelchair that supposed to assist and went to a long queue for transit security chk which was very slow and boarding desk wanted to close counter although that they knew that I am minutes away because of their mistake of not providing the wheelchair.

No bording was given for next trip on same carrier, food was very moderate.

No birding was given for next trip on same carrier, food was very moderate.

The line at boarding was not well organized and managed

Very unprofessional treatment of customers - boardring on being unethical. Only cares about money and not the customer. If you use the swiss brand, you should deserve it - now swiss air doesn't deserve the swiss brand.

Best international flight I have had in a while! Far superior accommodation, services, food and general experience compared to U.S. airline companies.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

The flight was generally good but was delayed departure meant a very late arrival for a connecting flight.

Delayed 30 mins Forced to check in my carry on luggage

I took this flight to be able to fly with Swiss instead of Air Canada from Geneva.. The AC planes have a better outfit in Business class than Swiss, but the service aboard Swiss is really best, first-class, as is the food and beverages. Though using the same plane model (A330-300), the interior setup of the cabin starts to show its age, but IMO the planes are better serviced by Swiss than AC. I had in my recent trips with AC way too many technical problems that led to delays or even complete cancellation of my flight.. Their fleet is aging (average 20+ years) and the maintenance has taken a toll compared to years ago. Cutting costs in every corner has to be paid sometime by someone, and it's the travelers at the end that pays for it. Unfortunately for me, flying directly to Zurich puts a much longer after-fly trip on me than Geneva.. so I might go back to direct flight YUL-GVA, even if I don't like flying with AC.

No fault of the crew, but the the rear lavatories were closed the entire flight. The front lavatories were blocked off for the first part of the flight by the food cart. Then some minor turbulence occurred so the fasten seatbelt sign came on for the second part of the flight. Heroic containment engaged! It was not fun.

Plane was late so luggage never made it to connecting flight. I’ve been home 2 days and still do not have my luggage.

Good BUT four days later I still don’t have my luggage. It never arrived. !!!!

Flight was late and crew were unwilling to help with information on connections. Call light had been on for 61 minutes without tesponse.

Food could of been a bit more premium, but everything was excellent. LOVED the innovative boarding drinks and terrific service!

Staff could have been friendlier and offered drinks more often

They have adopted a crazy "no paper boarding passes at all cost policy". We spent half an our at the checkin stall – my elderly mother and her grandchildren were flying. She had no phone reception for some reason (besides being an inexperienced smartphone user), the kids had dumbphones, And they still won't issue a paper boarding pass. We had to do a lengthy dance with getting the boarding pass SMS on my phone and transferring them to her phone via WiFi. This was horrible, honestly. I can't imagine how they could manage it without me being there. Trees (and airline profits) should be less important than people.

Staff friendly. Business class but issue with flat bed. Incoming Turkish flight delayed. Made connection due to fast buggy but luggage did not make it. Confusion at Delhi airport

With a 4 hour delay its was a very basic flight which was just bearable. We were offered food vouchers for the delay and then they didnt work, so that was annoying. Also poor communication about the delay which got pushed out 3 times.

Very good overall.... apart from the cost of extra check ed in luggage where they charge £17 per kg, and no option to just buy an extra bag allowance (at least on the route I took)

Very old plane on the Istanbul to Bangkok flight, had an emergency exit isle row, no where to put anything, on a plus point loads of leg room. Food was the best I have had in 39 years of flying.

It was a nightmare. I booked business class ticket from Ediburgh to Beirut via Istanbul to attend a funeral. I had a wonderful experience flying to Istanbul from Edinburgh. Then I could not get a boarding pass issued to Beirut. It seems that although they booked me and I had a reservation number, I had no seat allocated and the flight was full. I was asked to go from one desk to another and made to wait for 2 hours. I missed my flight as I did not have a seat assigned and it was full. The only option was to put me on the next flight, 6 hours later, for a fee of over $400. They said that was the best they can do to 'help me' and to 'take it or leave it'. Well, I was not about to be bullied; I stood my ground. I booked and paid premium for the journey, which was confirmed. The eventually accepted to not charge me extra and i waited a total of over 8 hours in the airport with no compensation. On top of my grief with the risk of missing the funeral service, I had to put up with their indifference and condescending attitude. They spoke about me in Turkish thinking I would not understand (I hold a British passport) in front of me. When they eventually handed my passport and boarding pass back to me, I showed them I was born in Istanbul and that I understood everything and said a condescending 'thank you' back to them in Turkish. You should have seen their faces. I said that consumers have rights and it is a shame that Turkish Airlines does not have good customer service to at least acknowledge and apologize for errors committed by the airline. Blaming the me, the client, for such an error and placing unreasonable ultimatums, rudeness and dismissiveness to be rid of me, particularly when I was vulnerable and visibly grieving was really shocking... The airline taints the city of Istanbul and the people of Türkiye. Such a shame.

A good airline, but at checking in, they allocated seats for my wife, and I far away from each other, and to change them, they wanted a payment, such a bad policy, it leaves a bitter taste in the mouth All was good on the plane, good food, but the air hostess was abrupt and a bit rough dealing with the passengers, but one has to find excuses for staff working under pressure

I found it okay. Did not think the food was that great. And the service could have been better. Seat was a little cramped. Delay getting to Istanbul made me rush all the way across the airport to get to the connection. This was a not good experience.

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

All great. Very efficient. Good emails that kept us in the know

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

That was a short flight by the only time I could actually sleep

We waited in line for more than 30 minutes to go through the check in (after the staff summoned us). Once on the plane we had to wait almost two hours before takeoff. The copilot said that it was not their fault but that the plane had arrived late in the first place and lost the slot to leave again because of the heavy traffic, This is completely understandable in our times, but I would have expected a little bit of pampering from the staff. We received a tiny little cup of water because we complained. Not a coffee, not a cookie, no music on the plane, no plugs to recharge your cellphone. It was very cold inside the plane and someone asked for a blanket for a baby - very harsh answer from the staff, no blankets on this plane. I think they should review their instructions and team spirit as traveling is also the experience, not only getting from A to B. And it’s not fun to interact with staff that doesn’t seem like they are enjoying their job. And as far as I know and judging from the cost of the ticket Brussels Airlines it’s not even a low cost!

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

The crew and the flight were excellent, the food might be better!

The Airline canceled my flight and don’t want to refund me.

My luggage was left behind in Miami. I wasn’t the only one. I couldn’t get a boarding pass from air Maroc but I got one from American Airlines for the air Maroc leg. I had the sense of getting in line with air Maroc boarding crew and showed them my AA boarding pass for air Maroc and I got a new one from them. There were several passengers filing missing bags reports in Casablanca so I assume there isn’t a good coordination between airlines. My AA bag ticket says Casablanca but it is from AA. I wasn’t the only one missing a bag.

My luggage did not arrive yet, it been 4 days without any information

Extremely Disappointing Experience Boarding was chaotic and poorly managed—we were left standing in the heat for 30–45 minutes with no explanation or apology. As a business class passenger, I was shocked when a staff member rudely refused to let me board after I questioned why I had to check in my carry-on, which contained valuables. Despite explaining my concerns, he remained unreasonably inflexible. Thankfully, the captain intervened and retrieved my bag personally. This same staff member was also loud and disrespectful to several other passengers. Completely unacceptable service.

Seats were very uncomfortable (tight and hard). Flight was delayed due to technical problems. Baggage took an hour to arrive to the carousel.

Plane is dirty Food quality poor Service was not good Lounge extremely bad

Check in process is terrible, only one counter opens to serve over hundred passengers, agents are incompetent and took too long to get passengers boarding passes. Supervisor is no help neither. On board entertainment 90% monitors were defective.

Pretty good flights! If they can let y u s know regarding delays by announcing it in the PA system it would be a good business practice!

I spent 4 hours untill get my bags no food no entertainment on the flight

I thought it was great because the seats were really comfortable for the long flight. The food was just ok, and could have been a bit better.
