Boarding is delayed! We are inside the plane without AC for a long time. No TV monitor.

Boarding is delayed! We are inside the plane without AC for a long time. No TV monitor.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

Looks like a local flight. Food was horrible. No entertainment system.

It never happened. Me flight from Doha to São Paulo was lated and the time of waiting for the luggage arrives when we arrived in São Paulo was about 1 hour and half. So it took a lot of time just waiting the luggage of flight that was already late, consequently we lost the flight to Recife with Latam Airlines and had to go to the Qatar office to arrange another flight to us to Recife, that one with Azul Airlines. It was more 4 hours waiting to this other flight to knows that this other flight was delayed too, total of 5 hours more at the airport to waiting to go home :/

I would love the entertainment center to be updated with more content. The flight to Doha had more options than the one to Miami

Awful plane to Tashkent. Not even possible to sleep. In business class does not even recline fully

There was frequent beverage ,meal and snack service. The crew was very hospitable and professional.

Ambience of the aircraft was great. Spacious seats with sufficient leg room in economy class. The layover could have been shorter.

Seats were not comfortable and touch free remote wasn’t working.

I planned to fly Qatar airways because I have flown them in the past and viewed the airline as a premium service provided. They still price this way but I found the experience to be subpar in several ways. 1 - check in - the line for check in was the longest I have ever had to stand it. Qatar airways does not have enough check in desks at the airport for the size of the flights they operate. 2- Carry on policy - there was little to no notification of changes to their carry on policy. Backpacks are considered a carry on rather than a personal item so if you have a backpack or larger handbag plus a roller size carry on, you were forced to check an extra bag or pay an additional carry on fee. This is not standard practice on other airlines and frustrating given that this was an international flight. On flight experience was good, generally comfortable seats, friendly staff and good meal service.

My seat/bed broke. Flight was delayed. Most of the cabin crew were very pleasant. Amenity kit was nice. Chairs and cabin was worn. Food was mostly quite nice.

The crew were kind and very helpful. Did not expect food service. Was served a warm soft sandwich bread , was delicious. Overall the service, the staff were great. Highly recommend others to try Turkish Airline

Cabin was kept very hot and it was uncomfortable. Entertainment system did not work at my seat. Crew and service is fantastic

Turkish Airline canceled our tickets in the very last minute, with our luggage and everything else, all prepared and good to go. It’s clear that they sold the tickets for better money to someone else. Bad, Bad, Bad business!!!

My experience with Turkish Airlines was good. I didn’t get the meal I ordered. So I didn’t have anything to eat which was disappointing.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

It was ok. Not the experience I expected from Turkish airlines

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

The crew was amazing. Super polite and welcoming. Excellent communication and service.

The seat did not recline and we called the stewardess, he forced it to recline, but when we landed, it did not come forward because the seat was broken. The stewardess came, He tried to do it but couldn't do it, the flight commander came and spoke to us in a bad tone, telling us to get out of here, she waited at the head and acted as if there was a child and we couldn't get up, it was very shameful, I don't even know if it's true, but she said if you don't get up, the plane will not land and will keep turning around. Then a passenger pushed the seat from behind and it worked. Then we wanted to talk to the supervisor again, but she did not come next to us. We fly so much and this is the first time we encountered such a style.

I travelled business class with my spouse from ATL to Helsinki and back from Riga to ATL. The seating was not very comfortable. Bread crumbs and left over disposable items from previous passengers were not picked up. The cabin was extremely noisy as the crew keep talking and laughing all night long making it difficult to relax or let alone sleep. Crew must make sure to keep the cabin as quiet as possible. The seating should add a privacy features such as curtain or something. Food choices are limited and average at best. I travel very frequently but this was my first time with SAS. I would try to avoid travelling with SAS in future and would not recommend it to my friends or family. My return flight Aug. 9th was cancelled for no specific given reason or explanation. The new flight on Aug 10th was delayed by 45 mins even though it took off on time. Sorry, if you are disappointed to read my survey but I have to speak the truth. Nayyer Islam, MD

Food and service were excellent. The lack of seat monitors for movies etc was a negative.

One of our bags was never put on the flight in Copenhagen. Now that we're home in the USA, my wife is still without most of her clothes and personal items as she returns to work this week. Hoping for a quick resolution, but there seems to be little chance of speaking with an actual person in the process.

Scandinavian was perfect. Nice A350 with an on time departure and an an experienced crew. What a difference from TAP.

SAS has too many other airliners. They don't need to exist.

Food could have been better. My pasta was microwaved into a solid block. Inedible.

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

They cancelled our flight home less than 24 hours before it was supposed to leave. It partially ruined our last day because I was on the phone trying to get 5 people home and the stress that it causes. We still arrived at the airport with no definite flight plans. The actual flight was good but my kids really misses the kids meals I had ordered for them which obviously didn’t make it to the new flight.

They were all bad because SAS was at fault and cost me my time. I will never fly SAS again.

The flights from EWR to Stockholm and from Copenhagen to JFK were great. Love everything from SAS

Boarding staff at lahore airport corporate well. Thanks to that guy.

Flight got canceled due to Middle East conflict. Just fly hasn’t refunded me the money

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

On this flight...fine. The one from India to Abu Dahbi, awful.

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

second leg was more comfortable. Customer service in Abu Dhabi is okay.

My wife and I were upgraded to Business Class on our Dublin-Abu-Dhabi flight on the 22nd of January. Being served by "Mariyan" (not too sure about her name, she's from Tunisia) was the real highlight of our flight, she deserves to be working with etihad. We are looking forward to the next upgrade as we are flying back to Dublin on February 01, 2024. If I am not mistaken we have just reached GOLD status as Etihad Guests.

Very unfriendly team. It was very difficult to get a cup of coffee. Legroom was extremely small. Old, dilapidated plane.

The seat was not functional. Very uncomfortable to sit upright for that many hours😢. There was no legroom. Can’t move the legs or the body. We should have the option to pick our seats. There was no need to call customer support team and have them pick and we pay for the premium seats. When I called the CST regarding the seats, their response is gaslighting. Total disappointment. We have paid to be tortured by Etihad Airlines.

Transit time could be 15 min longer atleast. It was right on the dot to boarding time. Giving minimal time to do shopping

I like the stripes, the more color the better I think you could even make more contrast with the stripes by filling in colors that create visual effect. The crew on both flights were polite well dressed, alert, good looking and very friendly. I never had a standing in line anywhere long for entering or exiting to my seat and it’s nice that people don’t bring too much luggage on the plane. The one thing I find is hard to manage is when a family or in general just being able to book a free seat if it is not for a dog, it shouldn’t be allowed. Since it is already very confined space on a flight overseas this can create slight conflict because there are sometimes free seats, which people then can freely use after cabin doors are shut. On the return flight, it was dark and by accident I stood on a paper bag with food in it that was placed on the floor in front of a seat next to me. I belong to the lady across the aisle and I felt terribly sorry once I found out there was still desired food in the paper bag. So I felt uncomfortable for getting into this situation. Otherwise I had a great time.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Crew and service was excellent. My seat was super small and cramped! No leg room

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.

We were helped whenever needed and had a pleasant flight.

Boarding is as always an issue. Slow and long boarding time.

Deplaning at Frankfurt required ck=limbing steep stairs with no provision for escalator or elevator.

Plane left 1 hour and 30 min late due to a faulty gate at the airport . they should have changed the gate immediately and minimize the delay. Due to this fact I lost my connection in Munich and ended up staying 12h in the airport . I got rebooked and for the troubles i got a 15 euro voucher witch is barely enough to buy a bottle of water in the airport . A bottle of water is 6 to 7 euros in the airport a sandwich is 12 to 20 euros . a sleep cabin is 17 to 20 an hour . their compensation is mediocre at least it has not changed the amount in the past 10 years , where the prices since then have . On top of this on my return they broke both of my check in bags another 500 USD damage

Another couple hrs delayed no compensation for the flight that was 11hrs delayed
