Overall the crew were friendlier than similar premium airlines like Cathay or Singapore. Seat was good. Food was excellent.. the starlink wifi was a real plus. The entertainment was just ok.

Very poor No information given to why we turned around.. No one at airport to help

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

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

I found it weird that the quality of the flight different from Australia to Doha than the Doha to Berlin leg. The quality of the toiletries pack (was in a box from Australia) and then a proper bag from Doha. The biggest variation was the inflight entertainment, which had a significantly shorter amount of content compared to the Doha flight. My QSuite seat was also broken and did not recline all the way flat. Wasn’t the best and I wouldn’t be happy if I’d paid cash for the flight.

The plane from Dublin to Doha was quite comfortable. I was in economy and the seats and rows were very tight. The man in front of me reclined his seat and it made my screen incredibly close to my face and I wasn’t able to take my tray down and my knees were pressed against the seat. I had to ask three times for him to pull his seat up but in his defence he hadn’t even reclined it far, the rows were just too close. I had a pain in my side by the end of the flight from the chairs which were quite worn and not very padded or supportive. It was a significantly inferior plane to the plane from Doha to Sydney and vice versa.

The overall experience for the price we paid was mediocre. Nothing outstanding! Check in process was standard. Flight attendants could have been more well mannered. I found it rude when the attendant nudged me with the snack box to grab my attention when not looking. She could have said ,’excuse me’ instead. My son’s in flight entertainment was not working. The food was not great either. The snack options were not so great with kids in mind. Overall, might not travel qatar again.

need to improve management and air hostess services. Rest of it’s OK.

Qatar screwed up by delaying our onward journey for refueling, which resulted in missing our connecting flight to India. the airport qater staff at Doha, herded us like cattle in a very incohesive and uncoordinated way. We were then given 2 options: either catch our original flight the Next day ( After 24.hrs) or catch 2 flights instead , to goto our destination in India. All this, for paying a premium for Qatar.

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

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

it was great honestly for the melbourne flight a kit with blindfold and slippers was probided to each passenger on the seat and the food was really great will definitely recommend people take turkish airlines for travel not just on the sin-melbourne route.

The crew were very hospitable and pleasant. The food was pretty good. Unfortunately, there was a flight delay of more than 2 hours. We're not sure why but it appeared to be outside the control of Turkish Airlines.

Boarding was much delayed, and there was no explanation ( obviously they were waiting for something or someone. ) Passengers were all crowded at the gate with anxiety. On the plane, the crew worked very hard on checking for safety and serving delicious food. They were polite and courteous.

Inflight wi-fi is below par and difficult to access.

Food was bad crew a bit nicer than other flights seats uncomfortable too

I was in business class, without the business class amenities. Large seat with lots of legroom, but no TV or bed. Food was okay, but I did enjoy the Turkish red wine.

Colocar pantallas en los respaldos de los asientos y mejorar la comida.

I had connection flight. I barely made it to the next flight. I had to run to get to the next flight which was far away from where my first flight was landed . On top of that they search my stuff before boarding that added to the time. Food was ok but they forgot to serve our row with drink and also when it was our turn, they ran out of second option for food and we didn’t have any options for food.
