Easy check in The flight was a bit delayed but the crew and flight were excellent

It sure why I’m being contacted by kayak, wrong info provided which resulted in quite a bit of confusion. I booked with experien, why am I being contacted by kayak?

Without a doubt, my “customer service” experience with SWISS was the worst of my life. Multiple disconnections in conversations, very cold and indifferent staff, failure to follow up with promised status updates — simply put, T. H. E. W. O. R. S. T. A full week later, and I am STILL waiting to hear from them. Never again for me with SWISS. Disgraceful.

One would expect far better service and quality of seats from Swiss. The crew was super cold at best. My wife and I are both Star Alliance gold members and none of them even bothered to come and acknowledge our status and make us feel special. Seat is in need of a major overhaul. It’s simply outdated and the TV screen is far too small. Food and drinks selection was very sub par.

OK they lost my hold luggage but notified me straight away. My main complaint, after losing my suitcase, I was told my cabin bag had to go into the hold because of it’s size. I, obviously, didn’t want this to happen bearing in mind what happened to my suitcase and when I voiced my concerns I didn’t get an explanation I was just told it would be taken from me on entering the aircraft. Looking around I was surprised to see many passengers not only with larger bags than mine but sometimes two or three bags,taking them onto the aircraft. In the end, nobody bothered taking my bag off me so I just walked on with it. The whole procedure was disjointed, poorly explained and not terribly efficient.

They lived up to the Swiss reputation of excellent operation in all aspects. Zurich is a great place to make connections to other parts of Europe.

We're talking about a short-haul in-country flight.. there is no confort, no food, just the bottle of water. The seats are squeezed like hell and I was in the back-end of the plane, with one spare row left for the crew and to store excess bags that could not fit in the overhead bin.. Speaking of carry-on, some passengers should be better screened as their bags were simply too big to fit in the overhead bins.. ! How can this happen, and it was an A310, with 2 columns of 3-seater rows.. There is a pseudo-Business class, which is simply a section in the front of the plane where the same seats are occupied only 2 out of 3, on each side, leaving more rooms for the passengers and their bags. That's it.

Super friendly crew. Leg space and entertainment system are below average

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Not exceptional but all good. Business class seats are like the domestic Mint class on Jet Blue. Comfortable but not exceptional. Food is good but not superb. Flight attendants were better on India leg than Miami to Zurich. All India staff was more professional and service oriented. Very polite and service with a smile.

Qatar Airways has consistently set a standard in my mind that very few airlines manage to sustain, and once again, this journey in Economy Class lived up to that expectation. As an avid globetrotter who travels extensively for work, I experience many airlines, service cultures, and levels of hospitality. Yet there is something reassuringly consistent about Qatar Airways. It is not simply the onboard service, but the entire experience: the professionalism, courtesy, warmth, attentiveness, and genuine sense of hospitality. The cabin crew are exceptionally well trained, composed, aligned, and polished in their delivery, yet their interactions rarely feel mechanical. They remain remarkably courteous while retaining a genuine human warmth and an apparent eagerness to assist. On almost every Qatar journey, there are individual crew members who somehow manage to stand out and make the experience even more memorable. What I value most is the consistency. Qatar Airways has established a certain benchmark of expectation for me and, over many journeys, has never underdelivered against it. There is a sense of confidence and ease that comes with boarding a Qatar flight because I know the overall experience will be thoughtfully delivered. For someone who spends a considerable amount of time travelling, that peace of mind matters enormously. Qatar Airways remains one of the airlines I genuinely enjoy flying, not because of any single aspect of the service, but because of the complete package and the remarkable consistency with which it is delivered. The only disappointment on this occasion was that my luggage did not arrive with me at my final destination in Kolkata (CCU), following my journey from Seattle (SEA) via Doha (DOH). Unfortunately, the baggage was delayed in Doha. A baggage exception report is already on file with the local airport team in CCU. Given the confidence Qatar Airways has built with me over the years, I remain optimistic that they will once again live up to that expectation, work their magic, and reunite me with my luggage within the next 24 hours. Looking forward to a swift resolution and, notwithstanding this final hiccup, another thoroughly enjoyable Qatar Airways journey.

The most convenient. Keep up the good services. Best wishes.

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

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

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!

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.

The crew were really bad mannered! And spoiled all my mood throughout the flight!

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.

When our flight was canceled and rebooked, my husband's meal request was not transfered. As a result, there was nothing he could eat for dinner and breakfast on the new flight, save a side salad and roll.

Very bad 3 times change the gate and too much delay...

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.

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…….

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.
