The best ever, friendly and attentive cabin crew, amazing captains who utilised their expertise for less turbulence, just overall amazing

Overall I was quite pleased with the experience; the cleanliness; the polite and attentiveness of the cabin crew; and the delicious food options.

I would never have been able to make the transfer in time without asking for a wheelchair

Good food, real silverware, polite staff, smooth landing, charging plugs, good entertainment options.

Loved that I had an exit row seat, and there was no one else in the row! And again, I don' use on-line entertainment at all (I read or sleep) but I very much appreciate that I didn't hear anyone else's entertainment!

The entire crew was amazing. They went out of their way to make us enjoy a great travel experience.

Loved everything! This flight had premium economy and I didn't see an option to upgraded to premium economy OR buy premium economy tickets. How come?

Some Crew were distinguishably fake in their interactions with passengers.

We was missed the flight They doesn’t lest us fly next flight without payment They charge me 606 hundred dollars What is very unacceptable,our first fight ticket was almost 2000 dollars, again paid 700 it’s hurt … airlines need to do something please

They were very pleasant and helpful. My husband and I were sitted apart. We asked if we could be seated together were told flight ws fuly booked but would try. After a while they were able to make it work we got seats together. Their food is good and attendents are very friendly/helpful.

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

Seats very small and unable to pre purchase internet or seat upgrades

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

riding in first class, you don't expect every time you order your dinner or breakfast that the first thing the stewardess says is Let me see if we have any left. Also, the food selection was not great: 3 of 4 entrees had mushrooms and I dont eat mushrooms, the 4th item was 'let me see if we have any left' and this was within 30 mins of entering the flight! Same experience level, it didn't feel first class this round.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Do I need to repeat my complaints about my lost carry on bag?

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

More facilities to transport to the gates......felt too much walking distance

The check in process at Istanbul airport caused my family a great deal of stress and disappointment due to the following factors: 1) WE HAD TO PAY US$330 for check on bags, despite holding Economy tickets that Turkish airlines website clearly states that flights from Istanbul to Miami had a 2 checked bags allowance. 2) Airport staff not only lacked empathy for senior travelers (75 yrs old and 71 yrs old), but were also rude as well. The supervisor at check it offered "if you don't pay for the bags, you can just remain and sleep at the airport for however long you wish. What a terrible way to treat customers !!! 3) We were bumped from agent to agent to agent FIVE times, showing everyone the communication we received telling us we had the 2 bags entitlement. Two elderly people lugging 4 suitcase around and around the Turkish terminal. Again, what a sad way to treat customers !!! 4) We need a case opened to get a refund for the amount we paid. Something is amiss, screams unethical, and sounds unscrupulous......At First , we were told we must pay for 4 bags. All of a sudden, it became 2 bags, and finally all 4 bags were checked on with payments demanded for 2. Why did it vary from agent to agent???? 5) OVERALL, A TERRIBLE AND SUSPICIOUSLLY UNSCRUPULOUS EXPERIENCE FLYING WITH TURKISH AIRLINES. WE ARE TERRIBLY DISAPPOINTED AND SAD THAT OUR VISIT TO A BEAUTIFUL CITY ENDED IN SUCH A HORRIBLE EXPERIENCE

I recently flew with Turkish Airlines, and I can confidently say it was one of the best travel experiences I’ve ever had. From the moment I boarded, the crew was incredibly attentive, warm, and professional. They went above and beyond to ensure everyone was comfortable and well taken care of throughout the flight. The highlight, however, was the food! I’ve flown with many airlines, but Turkish Airlines sets the bar incredibly high when it comes to in-flight dining. Every meal was fresh, flavorful, and beautifully presented. The variety of dishes, even on a long-haul flight, was impressive. It felt like dining at a high-end restaurant at 35,000 feet! The seats were comfortable, the entertainment options were great, and the overall atmosphere made the journey enjoyable. Turkish Airlines truly excels in combining luxury and hospitality. I wouldn’t hesitate to fly with them again—highly recommend!

One of the best flights I have been on in a while.

Here's a sample answer: "Honestly, I was really impressed with Turkish Airlines, but if I had to suggest one area for improvement, it would be: - *More efficient boarding process*: I noticed that boarding took a bit longer than expected, which might be frustrating for passengers with tight connections.

Not worth pay business class and get service economy class

In this long haul flight, flight attendants never stopped moving and giving excellent service. Very impressive. Very comfortable seats and excellent food

In sharp contrast to the modern glitzy airport, boarding facilities were primitive. Passengers had to board buses and walk up steep stairs in bitter cold with carry-on baggages. I found no reason why aerobridge was not provided.

Service and food were decent, seats are a bit too narrow. Leg room is normal. Bathroom should be cleaned more frequently. WiFi is cumbersome and should be simplified.

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.

Same as before boarding process and lack of crew experience in the process
