The flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.

Not consistent with the food quality (I mean taste not freshness)

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

A disaster. Air France is a real joke. They overcharge us customers for absolutely nothing. Service was very poor, food was mediocre, entertainment non existent, etc. We paid thousands of dollars for our business class tickets and then we were told in Paris we could not access its lounge. Really Air France ? Congratulations on irritating your customers to the sky high level and ensuring we will do everything in our power to discourage others to travel with you.

Good. Food items are ok but not really healthy (no protein for the vegetarian option, just a total of 2 gr total) so not fulfilling. Also, no airline is educating passengers to behave and have common sense: let the one sitting by the window pass first, leave toilets clean after use, etc. Humanity is just getting rude and more disgusting by the day and without education or enforced common sense no

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

Food could have been better especially the breakfast. Overall it was a good flight

Sky priority means you get to use the KLM business Lounge.

We flew business class and it was impressive. So comfortable with delicious food and very attentive and polite staff. Will definitely fly Turkish airlines again.

Entertainment was good. Flight was delayed, nearly missed my connecting flight. The gate was changed on several occasions. My luggage did not arrive on time and had to leave without it.

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.

Flight Singapore - Istanbul was perfect. Flight Istanbul - Sao Paolo - Buenos Aires was really good but there was a big delay in Sao Paolo (Brazil) due to a problem with the ground staff and not related to Turkish Airline. Overall a very good and solid experience

The fully flat bed in business class on the 777 is a little narrow, and the 2-3-2 configuration is now dated, but otherwise a comfortable and pleasant flight. It’s hard to beat the value too.

Seats were in disrepair. Seat back pockets were all broken. Seats recline very far, which is comfortable for occupant, but confining for person behind.

Unfortunately internet was down and they couldn’t fix it in a time I needed it so urgent to stay in touch with work

This time around, I felt that the crew wasn’t very professional. Speaking / laughing loudly and rushing through service.

I canceled this flight after turkish airlines did not provide any consideration for a death in the family while in Singapore

I asked for blanket extra because I got cold. No body came back. I asked for chai it was not good. Sorry to say.

I appreciated the vailability of wheelchair services for persons with mobility issues all the way up to the aircraft. What could be better would be the food choices.

As good as you can expect an economy flight from Europe to Australia to be. Nothing agains Qatar, just feels like every new generation of plane gets tighter.

Awful plane to Tashkent. Not even possible to sleep. In business class does not even recline fully

Seat experience average as they use old 777 for must flights despite full load. Qr fares are higher than other airlines for same routes so they should at least upgrade the planes . Food is average and same dishes for months on most routes I travelled at least - the Arabian rice dish “Maqboos” on every flight for months - I am sure there are other food Arabian dishes ?? It’s become boring ! Crew is always good which makes up for these things but hey confirm us what we need

It was the terrific, I was promoted to businessman class, and the service was amazing.

Food could be much better. Entertainment needs lot of improvement. The luggage came out open with broken bags. The flight landed at 3:15 PM in US and by the time bags came out it was 5:15 PM or so. Staff at airport was aggressive and not polite.

Fine. Don’t think I would fly with them again

Qatar Airlines code share with Indigo has been a terrible experience for me on these notes: 1. Indigo changed by flight without informing me of the change, they did not ask me if I am okay with the change. I discovered this change when I was trying to do online check-in through the Qatar mobile app. When I called Qatar customer support, they mentioned Indigo changed my flight due to the original flight being cancelled, but the fact is that flight was scheduled and departed correctly, it was never cancelled. 2. When asked why my flight was changed without informing me, they mentioned that they sent email/phone call to my travel agent, and it is was my travel agent that did not inform me, which again was another false statement. 3. I called Qatar Airlines (third call on the day of my trip) to request them to put me back on the same flight, they mentioned that they could for an extra $2500, as the original class I was booked on was not available, we are still talking economy only not business class, I said no way. 4. I called the travel agent, and they mentioned that they will work with Indigo and asked me to be prepared to travel on the later flight I was bumped to. While I was making my hotel/taxi arrangements for the new flight, I got a call and email saying they were able to get me on the original flight with no extra cost. So, after 2+ hours of talking to customer support, and a lot of stress on my last day of vacation, I flew back as originally scheduled, but this nightmare is just a horrible experience that I will never fly on Indigo/Qatar again. Thanks and regards, Vijay

Everything was top notch. Only issue was the delay, but Qatar worked diligently to get me on the next flight. They were kind to walk me to their lounge in Doha to make sure I ate, slept and showered.

Seats very uncomfortable, impossible to sleep. Food average, bakery items not fresh. Pockets in seats not large enough to hold a book and a few other items. Cabin temperature too cold, even with blanket. Good selection of movies. Other than that 12 hours of torture!

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

Business class ticket should include lounge access and seat selection. The food quality and varieties should be more. It was surpirise that no dessert was offered.

It was an old plane with seats not comfortable and with little space for the legs. I must say that the previous flight I had was amazing on a very comfortable new plane

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

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

Online was good boarding also but a child was crying all the way with no intervention from crew member.

It feels like the seat did not have any cushion just plywood. The seats are so compact that I could not even move at all and I am slim. Just imagine someone else. Singapore Air and Emirates are far far better than this. Do not even travel for free. For a 12 hour flight sitting on a plywood is horrible experience and on top of that the person at checking counter at NY was worst and rude. Plus they charge arms and leg for everything. I think they would also start charging for belts and oxygen also soon. First and last time flying with Ethiad.

It feels like the seat did not have any cushion and just ply wood. The seats are so compact that no one would sit comfortably. I am a slim person and it was super hard for me to move in the seat just imagine what someone else would feel. This airline would be my last option. Singapore Air and Emirates are far far far better than this. Do not travel even for free.

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!

Poor communication from airline, didn't start boarding until 15 minutes after we were supposed to be in the air and there was no communication from anyone about a delay except the screens showing we were "on-time" and already "boarding" which finally updated 5 minutes after we were supposed to be in the air to "delayed".

The business class seat is the same as economy with 2 people instead of 3. That's not how it should be.

Checking in could not be done in the UK for this prt of the flight . Since we only had an hour and a bit at Singapore it was very stressful not knowing if we had appropriate seats. The flight itself was Ok and the 787 had a bit more legroom than the777 from Munich to Singapore. Food wasn't great.

Prompt boarding, safe landing and they didn't lose our luggage. No entertainment and no USB plugs to charge phones. No food, though I might have been asleep.

Flight was good, staff members were helpful and energetic, food can be more tasty.

I was served cheese that had mold on it. I brought this to the flight attendants attention and she informed her supervisor. They were apologetic and offered me a replacement, but I think that is extremely insufficient compensation given I ate bad cheese causing food poisoning for my birthday vacation. Both me and the flight attendants photographed the cheese, and I was told they’ll “put in a ticket” to ensure it doesn’t happen to someone else…….

The experience was as expected…. “Nothing to write home about “

You get what you pay for. Beware 747/8 entertainment interface ...the touch screens are rubbish.

Plane was very delayed. US agents unhelpful in connection flt and in seating. No real info given on delay.
