Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

All in all the flight was good. Love the fact that for airline food it was piping hot

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

Wonderful service, planes and interior in great condition, very pleasant experience

Every thing was fine. Some ild classical Hindi movies should be add

The premium economy seats were not that great. It could have been more premium than economy seats.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

Fantastic, the 787-9 is a very beautifully designed plane and it was a pleasure to fly in the Qsuite. The suite did feel slightly smaller than the 777 variant, and the suite door also felt smaller, as I felt more exposed as passengers and crew walked past. Food was too notch, and the service was fantastic. I wish they’d enforce boarding zones more effectively, but otherwise they did really well.

From Montreal to Doha , we habe two complaints : 1) They want to charge for Seat Selection, claiming that the Class of ticket bought on Kayak did not cover seat selection. It such a penny pinching rule, I told them, since we paid almost $20,000 our 3 tickets , that rule should never exist. Also I reserved my tickets so many months ahead, I expected they will naturally put the family together or move somebody else to keep our family seating together. I filed a complaint, and NOBODY ANSWERED. 2) In Montreal, Qatar has an arrangement with the National Bank Lounge. It was so overcrowded and the Lounge is so bad in terms of service and food, amenities etc... The WORST lounge . Why Qatar not have another arrangement their Business Class clients in Montreal. The Air France KLM Lounger is better, the Air Canada Lounge is better. Qatar should send somebody to take a look ! Joseph Chung

To many ads. 3 or 4 between each movie. All repetitive, all related to Doha which I was just passing thru.

I had never seen any cabin crews behaving like that. They are not at all professionally fit for this job

Crews are very rude and unhelpful. Cramped seats in economy. Foods are useless

The business class experience was awesome - I will be using QATAR airways again and it'll be business class again - appreciate the privileges afforded to the business class clients - thank you.

Terrible. The website insisted that I wasn't logging in correctly to confirm my flight. It also wouldn't let me register as a member. I was unable to get a boarding pass until 4 hours before the flight so I couldn't get through security and had to wait. It was unlike anything I've experienced in decades.

Boarding process was terrible. Will not travel Qatar Airways if I had an alternative. The food was one of the worst, even for airline food.

Lovely aircraft and I flight entertainment. Good leg room. Full flight crew struggled a bit

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.

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.

There was a Turkish Airlines employee sitting in front of us, we noticed from her conversations we witnessed with the cabin crew and the fact that she boarded business class. She was sat in 16A. Firstly she was talking loudly the majority of the flight with two other men, one of which was leaning over the seat in front of her. This was disturbing as they were talking loudly and we were not able to sleep. The 12 hour long flight turned into a nightmare, even the noise cancellation didn’t work for their chatter. Secondly she requested extra meals from the crew for her male friends. We believe the meals came from business class. They also took their e-cigarettes out and were caught the cabin crew, but no further action was taken. Sitting in economy and seeing this is extremely disheartening. Next time I will book Emirites, I don’t think their staff would be allowed to behave like this.

for the very long way the flight has to be more confortable it was very dirty the wc was not clean

COmpared to my experience in the business class of other airlines the food variety and offerings were meager. They did not have any cookies or crackers for snacking! They were unable to offer some other items. This has never been my experience in other airlines.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

Turkish airline always good Only Turkish representatives at the gave need to be more helpfull to any staff who traveling on Turkish airline . One situation happened Ist to jfk on Feb 29 TK3 had seats I asked them to transfer me to tk3 because Feb 29 tk1 was oversold and they advise me that I might not make it for tk1 I asked them to transfer me to tk3 and they say no they can’t do it I been telling them you know that I don’t have a chance for tk 1 why would you let plane go with some empty seats on tk3 if you can transfer me to tk3 and have less staff on tk1 and still told me no I waited for tk1 9 hours and only last minute I got seat on tk1 It was not easy situation but I am glad I made it home Thank you Turkish Airline One more suggestion for Turkish Airline you need to make a FIRST CLASS cabin it would be so cool 🆒 Good luck all the best See you more

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 am writing to express my extreme dissatisfaction with the recent flight experience I had with your airline. This has been one of the worst travel experiences I have ever encountered, and I feel compelled to bring it to your attention. Firstly, I missed my flight due to what I perceive to be a lack of clear communication and coordination on the part of your staff. There was no remorse or apology from the airline's representatives, which further exacerbated the situation. As a result of missing my flight, I was subjected to a 24-hour delay at the airport, where I had to spend a significant amount of money to rent a hotel room and cover other incidental expenses. Additionally, since my baggage was already checked in from Tanzania to Turkey, I had to purchase essential items for the 24-hour period. What truly dismayed me, however, was the discourteous and unprofessional attitude of your staff. Their lack of empathy and understanding only added to the stress and inconvenience of the situation. I have been traveling abroad for over 20 years, and I can confidently say that this experience has been the worst I have ever encountered. As a result, I am compelled to reconsider ever using your airline again for future travel. I strongly urge you to address the issues I have raised and take immediate steps to rectify the situation. Additionally, I expect a formal apology and a refund for the expenses I incurred due to the airline's negligence.

The airplane from IAD to Istanbul was too old. The chairs were to tight and uncomfortable. I continued my travel from Istanbul to Bangkok. This airplane was better and newer than the first one. Even food was better.

The flight was delayed as they were waiting on catering. Catering. Was eventually delivered but they still had no food. No meals for us in business class - just a bag of nuts.

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.

Self check in Kiosk did not recognize that I had prepaid for my luggage. This caused a 40 minute delay even though I had my British Airways email receipt for the prepaid luggage.

Crew were very friendly and helpful. They explained to us in detail the delay in our takeoff due to the storm that rolled in from Belfast and did their best to make up the time. Always great to fly BA!

Staff were very helpful. The free WiFi for messages was also very useful to keep in touch

Crew was more interested on looking at their phones than welcoming passengers during boarding.

Communication was terrible. Flight was delayed for 4-5 hours in DC (on the front end, and also after we boarded, we had to get off - some issue with fueling the old plane correctly). There was little to no information on timing or what was happening. Once we reach Delhi airspace, apparently there was weather that caused us not to land - we were actually near the ground, saw the run way, and lifted back up to the sky after being sooo close. Then we circled for about 30 minutes, and they decided to go to Jaipur to land until the weather cleared and to refuel. Again, once we landed in Jaipur (wrong city), there was little to no information on timing or what was happening. Then we heard that the crew was reaching their 24 hours. We sat on the place, on the tarmac for another 3 HOURS, with no food and not enough water for everyone on the flight. Then, they kicked us off the plane with no plan, in the wrong city. We went thru customs, got our bags (thank goodness), and had to ask a bunch of staff what was happening and what to do. Eventually, their soltuion was to bus people back to Delhi (like 6 hours we were told) but not everyone would fit on the bus, and unknown timing on when it would leave. At this point it was 9PM (we were scheduled to arrive in Delhi at 11AM...). My husband and I decided to risk it and take a cab that we had to pay ourselves (about $200 US dollars) to get to Delhi (about 5 hour drive). We both had terrible trips back to the US as well - almost missed connecting flight, forced to pay for carry-on luggage (a small back pack!) and duty-free goods by the Air India staff last minute. Just terrible experience all around. Never again with AI! The ONLY good thing was the air hostesses were kind and patient - example: they made sure people with food allergies got their correct.

The Air India lounge in Delhi , was very disappointing! The food was of poor quality and options were limited especially for vegetarians!! Beverages were fine. The in flight crew was excellent! . They helped me with my seat controls - the controls did not work without a hassle or assistance!! A very poor showing for a Business cabin!!! Post flight , the wheel chair passengers ( including Me) were “ shepherded and left waiting twice (an hour or more) before taking us to immigration! I chose to Fly Air India because I want. to patronize our National carrier with the hope that the experience will improve!!! Regrettably, I will have to look at other options for my next trip to India

It would have been perfect if there was onboard entertainment.

Interment is zero tv wasn’t work phone charger plug doesn’t work moves doesn’t work

Worst International flight I ever had in my whole life time. Boarding is the worst of all and flight experience was also not good. Screens were not working, seats were not comfortable and lot more.

Everything! To start with, seats, food tray table, entertainment console all are broken! Imposing duty free baggage fees for $250 as a surprise penalty cannot be appreciated! Airlines should be responsible for transferring the checked baggages to the connecting flight. Having customer go through the transfer is painful considering the travel tiredness! No soft drinks served on flight is another crumble!

Air India need a big change of in all departments.

Boarding and crew were nice Food was normal No entertainment was on the flight. Neither TV screen was there nor Wi-Fi connection to the mobile phone or iPad was there. Even the budget wing of AIR INDIA ie AIR INDIA EXPRESS provided us Wi-Fi connectivity on our mobile phone in their DOMESTIC SECTOR. So not providing Wi-Fi connectivity on international flight was unthinkable.

Old aircraft, crew were so so. Meals were mediocre. Flight to delhi was delayed. Lounge needs update and was mediocre too.

Upgradation in our flight seats made us happy. But the long time to catch connecting flight from Bombay to Hyderabad could have been avoided or shortened. Our was AI 116 from JFK NY to Bombay & A1619 from Mumbai to Hyd.
