It was delayed for 2 hrs. Flight attendants were not attentive.

We boarded but due to a technical issue we spent 4.5hrs on the ground waiting for the issue to be resolved

No kids provided. Instead we were told to have contacted the airline that we have kids and require kids meals. We were not the only ones who inquired about kids meals. It’s odd. Emirates and other airlines give kids meals as standard and before the adult food comes out. The rice in our meals was gluggy and under cooked. The chicken was also raw. Sadly not the best experience with Finn Air. The hostesses tried to compensate with the snacks and drinks but missed the mark by a long way. Especially when paying Emirates/Qantas prices

They cancelled our flight, rebooked, cancelled that one. We are now flying New Zealand Air and need a refund please. How do we get it?

Wifi was not operational for the whole trip. Other than this, flight was well received .

Food no so good. Extra charge to much for front seats cost me £163 then other people sat near me for nothing 🤬

Comfort and customer service from most if the crew was great. The crew reassigning passengers should consider the presence of infants when reassigning seats. Unfortunately a couple of oversized passengers were relocated next to us, making this segment a bit uncomfortable, as there was not only extra leg space required. I ended up swapping seats with my husband so our baby wouldn't be impacted. My husband travelled quite uncomfortable as the reassigned neighbour shoulder and arm ended up on my husband's seat

Seats are not as easy to move as you would hope in premium econo Y

The plane was very old and uncomfortable. Service was very slow!

Flight from Dubai to Zagreb very bad cabin crew. Bad food

Both of our Business Class seats were broken. I'm sure they didn't just break before we boarded but were broken prior. They would not recline. We could sit up straight or lie down, nothing that would allow us to sit back and relax on a 12 hour flight. Totally unacceptable. Very expensive and a waste or money.

had to wait 1 hour once boarded. so we were 1 hour late arriving.

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.

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

The flight was delayed both legs of the journey. The seats were cramped.

You need to weight all bags together because we were 2 and we allowed 4 bags plus hand carry and personal items. We trying to saved bag like we put our stuff in 3 bags so we don’t have to carry more bags and airline also save space time less bags less work. We had only 1.6 kg over and we requested crew he said it’s airline policy that you need separate bag that’s ruined our mod and carry that suit in our hand in plastic bag he didn’t understand that we have less bags that make sense if we brought over luggage then it’s problem. I think if you guys change your policy and weight all together that will be good

I took a nine-hour flight in economy class, and the seats were quite comfortable. I even managed to take a long nap, which rarely happens. There was a good selection of movies, and the complimentary kit included socks, ear plugs, a sleep mask, lip balm, and a toothbrush with toothpaste.

Don’t use them on the IST-isb route, horrible service

they were much nicer on this flight. however, my baggage was delayed by one day, and one of my suitcases arrived broken.

I requested a special meal (kosher) several months ahead of the flight . It was listed on the Turkish air website that I had a kosher meal. In-flight, there was no kosher meal. I was not able to eat during the nearly 8-hour flight. There also was no kosher meal on the second leg of the trip. The flight attendants said there was nothing they could do. They had no idea why the kosher meal was not provided. Very bad meal service.

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

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.

Nice airline. I was in a really weird seat which had extra leg room, but no basket or stowage. And the people next to me were pretty noisy during the flight, so it was hard to rest. I wish staff came around to pick up trash more often as I had no where to put it except my lap or the floor.

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 crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

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.

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

I paid for international flight experience but instead got domestic flight experience through indigo - the seats were not comfortable, lacked charging stations in seats, no head rest. I feel cheated for the money I paid for the ticket.

I payed for extra leg room but in last moment my seating place was changed and i got standard one seat. Staff was not able to do anything , so was very disappointed because of this.

I liked the crew, the food and the foot space. I did not like the comfort of the seats.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

More leg space than other flights, but *maybe* narrower seats

The check-in has been the very best so far I didn't get to use my priority access which made me feel like a paid a higher price with no benefit for that I loved the food Very tasty and hot The staff friendliness, empathy could be better as it was not linear amongst the whole crew Otherwise, no complaints. I'd still fly again via Etihad Great prices despite the long 6h of waiting time

Surprised at the lower quality of seats on the Boeing 777 in Business Class. Seats are tight and the whole Business class section is jam packed with seats. It doesn’t feel like Business Class at all. Also the way the tray tables are placed with a huge bulky solid metal hinge at knee level makes it so uncomfortable and always anxious that one will accidentally bang their knee on it. Quality of amenities has also declined. Over priced tickets with diminished quality of the entire experience.

In never flown this flight, because my flight coning from Barcelona was delayed.

1st time with. Etihad Airways and it was amazing from check in to crew. Great flight.

The legs room was not enough at all. The seats are not comfortable enough for long journey but other than that it was very good

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

It was not British Air, we were put onto Air Portugal for our London to Lisbon leg.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

The on flight entertainment system touch screen system and the USB charger did not work on multiple seats on least 4 seats an in different rows. The attendant tried to reset the system but was un successful. I couldn't change my phone to get my ticket for my next flight. This was an international flight I changed seats and the problem was the same. the flight attendant offered his power bank

Plane is old. Toilet did not work. Once in Singapore the continuation to London was cancelled.

Business class was nothing more than Economy with middle seat empty. Uncomfortable seat and leg room. A mom behind me had a 18 month/2 yr old on her lap, who had his feet on my back all the time- while middle seat remained empty. Pretty much not worth the fare. Very disappointed.

Once again I purchase a business class ticket and the seat is exactly the same as cattle class, the only difference being is that BA install a janky table over the middle seat so there is somewhere to place your complimentary drink, the tray table is just big enough for the small tray, so if you are not concerned about getting fed and watered on the plane or getting access to the BA lounge I would save your money and fly cattle, PS the cabin crew were exceptional in every way, shame about the equipment

When bussing people to/from the gate, don't pack everyone in like a can of sardines and don't send the bus on its way if the plane isn't ready. Waited for about 40 minutes packed in this bus...both ways!

A Perfect 2.5 hr flight. No amenities, but we did not expect any.

Delayed flight by 45 minutes. Need a refund to compensate for the subsequent itinerary changes

The flight was delayed and absolutely packed, we had to dispach our hand luggage which contained some fragile items, luckly nothing was damaged.
