Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

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

Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

Can’t complain Only downside was the Kiosk passport check and customs clearance at Melbourne. When will they improve that service🤔

I lost my lock from my luggage, I don’t know someone took something from my bag.

We travelled in economy, were very satisfied with the comfort and keg space of the seats. Food was great compared to other airlines, the crew were very helpful and friendly. Since i was travelling with kids, i needed assistance multiple of times. Will be definitely taking long flights with Emirates from now on.

Emirates First Class is always a treat with Caviar and service is always personalised.

Very pleasant.The crews are very nice.Food were excellent.

Emirates is superb service. The A380 was very comfortable. The cabin crew is really helpful

Everything I was good except food quality is very poor

no qatar did noting wrong Kayak messed up my whole vacation . Went early to check in at The Cairo, Egypt airport to find our I had not tickets to board , Kayak and/or Affirm never sent the money for my flight that I paid for and booked. So I had no flight at 12am in a foreign country and I had to scramble and find anther very costly other option just so that could fly home. Fucken horrible experience.

Seated in row 6 you are separated from business class close to the toilets. The is a high panel in front that obscures forward viewing, coupled with no window view. Service is limited as the area is not in view of the attendants. It is closer in proximity to economy than business class.

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

The flight was operated by IndiGo and not Qatar, which is a budget airline from India. Nevertheless, the flight was uneventful.

The seats were uncomfortable. The service was poor. We bought internet for my family and myself and it didn’t work. The charger for our phone didn’t work. The service seemed like they were tired and exhausted and seemed a bit upset. It was not a good flight. Our flight from miami to Qatar was great but from Qatar to Tokyo was simply awful

I purchased Qatar airways after seeing ads about its service. To my surprise Qatar is marketing gimmick and horrible airlines which I don’t recommend to anyone Flight was dirty including flight from Miami to Doha And Doha airport restrooms are dirty On top of this they use this pathetic cheap indigo From Doha to Hyderabad which I will never fly Also they lost one of my baggage in Indigo and still waiting to receive it. I will never travel Qatar and will never recommend

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

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.

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

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

It was great! Great value for the price I paid. Great crew and great food in business class

On the Boeing 777-300 aircraft there is no personalized climate control for passengers. Every time I've ever flown on this type of airplane I've been uncomfortably warm. For shorter flights (less than 5 hours) this isn't a big deal, but on longer flights where a nap is required to stay comfortable it turns into a nightmare. I love turkish airlines, but I really fo hope they upgrade their fleet. I've flown turkish air once on a newer model and had a fantastic time, so I think its the plane more than the airline.

I had a bad experience with the Airline company. I still did not get one of my baggages. I went several times at the Airport looking for the missing luggage.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Outdated business class on this aircraft, no flat bed, and even minimal recline. Couldn’t sleep at all. Laggy and outdated entertainment system. Food sub standard.

The best airline food being served for business travellers. Excellent food.

With a 4 hour delay its was a very basic flight which was just bearable. We were offered food vouchers for the delay and then they didnt work, so that was annoying. Also poor communication about the delay which got pushed out 3 times.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.
