The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

The biggest let down was with booking experience through Kayak. I booked a flight with checked bags on Kayak. Right away I got a message from travel agency that the flight is not confirmed and to call them. I called them and they said the flight I have booked is no longer available with the price I have booked it for and I can book it with about $100 more. I already had other options I could book with cheaper price so I asked them to cancel my booking. Then they said I can have the ticket with the same price but a date change which was not working for me as I had to be there for a seminar. So again I said no then they said they will cover the charges and confirm my flight. When comes time for check-in I see I have no checked bag option which means the travel agency deceived me saying I can have my booking as I had booked it. And at that point I ended up paying $155 for my checked bag going back and forth. I am extremely angry and unhappy with this experience

It was great. My seat was comfortable. The bathrooms were clean . The service was superb . I travel a lot and I have been in 64 counties. I wish I could fly first class, even though I could , but I prefer to budget my yearly travelling expense on actual visiting , not on flight. Anyway, my point is that your economy was far much better than other airlines as good as Air France. The flight attendants and all crew were polite and very helpful and respectful. Thank you for making my long trip tolerable.

I slept the whole flight so I can't tell you about the food and there was no entertainment offered. Crew was very nice, seats were comfortable in business, and boarding was easy.

I haven't flown Swiss in a long time. I was disappointed that after paying $14,907 for 3 business class seats, we still had to pay another $200 for a single business class seat. All the window seats used to be single seats. Now it's every other one and if you want a single seat it's extra. Also, The double seats do not have pods or any privacy. We landed in Chicago after a long 10 hour flight and our connecting flight was on United. Because we do not have status on Swiss, we were not allowed to use the United lounge, even with business class seats. My father is on crutches and we had a 4 hour layover. No lounge was also disappointing. All of my status is on British Airways so I will go back to flying BA. We flew Swiss because my father did not want to go through Heathrow. On a positive, the crew were super nice and accommodating for my father who had recently had hip replacement surgery. Food was okay. I"m not a good person to critique the food, I never like airplane food.

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.

Nothing special.. they could have provided something to eat without a charge

For the price of the ticket it's probably the best service in the world

Crammed like sardines into the middle of the middle 4 seat row for an 11 hour flight was a terrible experience. No attempt made to help passengers sleep by dimming lights or shutting window shades. Small mediocre meals. Not enough good movies/TV options. Hopefully we will never have to do this again.

Flight attendant served beverage to everyone during meal service and forgot about me. Had to call her several times until she realized it. Not a good service for a business class flight

The flight attendants were great! The seating for business class is better on other airlines. The food was also good!

Flight Singapore - Istanbul was perfect. Flight Istanbul - Sao Paolo - Buenos Aires was really good but there was a big delay in Sao Paolo (Brazil) due to a problem with the ground staff and not related to Turkish Airline. Overall a very good and solid experience

The seat 7A had no padding. I needed to sit on the provided pillow.

Turkish Airlines overbooked the flight and they did not allow me to board the flight even though I had the proper boarding pass and was at the gate on time. Simply unacceptable.

The fully flat bed in business class on the 777 is a little narrow, and the 2-3-2 configuration is now dated, but otherwise a comfortable and pleasant flight. It’s hard to beat the value too.

Boarding was chaotic. Cabin noisy. Temperature a bit cool. Bathrooms not cleaned enough.

they have cancell the flight with no reasons, My parents were in the cold weather in the airport for 24 hours they did not give any hotel and food. I hate Turkish Airline, this is our last time that we ha ve chosen Turkish Airline.

they have cancell the flight for no reasons and 24 hours my parents were in the Airport they did not give them any hotel any food, I hate Turkish Airline.

Good overall flight. Excellent crew. Food options could be improved.

The trip had a 19 hour layover, and no hotel accommodation was provided. This a shame for an airline to do to their customers. I will not only stop flying with Turkish Airlines, I will make sure anyone I know avoid Turkish Airlines because of how lousy their layover system is.

Very helpful crew, including airport people, getting us in wheelchairs and working so hard to get us where we need on time!

I've yet to be on an Air Dolomiti flight that hasn't been delayed, but other than that I've really enjoyed flying with them

Service was courteous and attentive. Sat in the exit row. In exchange for leg room I had people tripping over my feet to use it at a hallway from one aisle to the other, had no access to films viaa viewscreen and no underseat storage for medicines or other personal travel needs. Next time I am seated there, I will refuse the exit row.

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!!!

New and clean plane, lots of entertainment on IFE. Boarding was chaotic, maybe because of the size of the gate area. Plane arrived half an hour late.

Great crew dealing with the most unprepared family with a million kids and zero sense.

We were delayed taking off which caused us to miss the connection to Orlando in Frankfurt. The gate we landed at in Frankfurt was in A terminal and the next flight was c15 which was impossible to get to even running. Very poor planning on Lufthansa’s part.

Seats were very small and of poor quality. Service was good.

Problems checking in. Charged for bag which was to be included. Repeated trials with in line check in process

The flight was cold, no enough blanket and the crew said that they can’t change it. I got very sick in the flight . Most of the kids were coughing.
