All great, because I was given a seat with extra legroom on this part of my trip.

All great, because I was given a seat with extra legroom on this part of my trip.

Qatar maybe considered one of the best ailines in the world but nowadays it is much of a muchness with the rest

It was excellent in all respects. I don’t think it needs any improvement

Don't be afraid if you board an Oman Air Airbus A330 - it will take you to Colombo and not Muskat. The Aircraft is leased by Qatar Airways ;-)

The crew was courteous and efficient. There was no entertainment or liquor service on this short international flight.

Other than low space, which is the problem with all airlines for economy class, the flight was excellent.

This was a really enjoyable flight. Even though I was in economy, I had a great deal of leg space, I had a nice meal, and the flight staff was helpful and friendly. A really great flight.

Changement heure de vol et je dois attendre 9h à Aeroport de DOHA.. C'est inadmissible.. je dois réfléchir avec Qatar la prochaine réservation

Excellent service and very comfortable business class for a long journey. Carry on bags in business class weight limits

Food Free wifi could be better. Its a very long flight and not a cheap flight. Free wifi is good to have. After paying $2k on economy free wifi should be part of the flight ticket cost.

Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

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

Changed to older plane with old set-up in Business class.

PLEASE GIVRE US PERMISSION TO BOOK SEAT NUMBER EVEN WITH FEES

Luggage never made it it’s been 2 days and no proper update

Amazing service on board in business class. The lounges are also great. The inflight entertainment could do with a larger selection and the food choices more but overall, very pleased.

Seat changes at the last minute Horrible checkin process Sad to see excellent airport with very poor service

The seat did not recline and we called the stewardess, he forced it to recline, but when we landed, it did not come forward because the seat was broken. The stewardess came, He tried to do it but couldn't do it, the flight commander came and spoke to us in a bad tone, telling us to get out of here, she waited at the head and acted as if there was a child and we couldn't get up, it was very shameful, I don't even know if it's true, but she said if you don't get up, the plane will not land and will keep turning around. Then a passenger pushed the seat from behind and it worked. Then we wanted to talk to the supervisor again, but she did not come next to us. We fly so much and this is the first time we encountered such a style.

First class payment but wife’s seat broken, would recline but not lay flat. On previous flight, delays and ground crew malfunctions connecting jetway made us miss flight to Houston. I asked twice for a cart to assist us getting across the massive Istanbul Airport, but was denied. We are both over 70.

Business Class Service was unacceptable. 7 flight time changes and delays

Maybe some more information as to why the flight got delayed I understand may be tell your customers that missiles were fired at a specific airport wouldn't be reassuring to the customers and would cause mayhem but something like recent events have cause a delay on your flight or smth

i have book the flight with baggage. and i have paid $800.00 for the baggage. when i contacted to JUSTFLY Costumer Service they told me that my baggage was included in the booking. then why i have to pay. i am going to file a complain against it. $800.00 is not at all small amount

Unfortunately the flight was cancelled so I never got to go

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

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

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.

I request kosha food all my flight but this flight didn’t imclude my kosha meal.

Nothing was good. Everything needs to improve. Everything was abysmal. Needs lots of improvement. The check-in and baggage drop at the New Delhi airport was manned by disrespectful people, horrible experience. We will never travel by Etihad ever again.

That was the last time I booked Kayak. The connecting flight got canceled and the trouble shooting terrible. Next times, I will book the airlines directly. Good bye

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

Way too crampled. Charge more and put in less seats.

I was first assigned a seat that could not recline fully and was at the back of the craft. I was not able to select another seat during check-in even when opting to pay for selecting a different seat. I had to contact the airline and spent 25min with a chatbot and was then transferred to an agent who was very helpful and could change my seat (free of charge). The entire process took me one hour. If I happened to not have that hour available this would have been a problem. And that was only to check in. The next problem is that the airport lounge I had access to is located landside. How strange. So it means that you need to allow time for security check and passport control and boarding time when leaving the lounge, which makes it almost pointless having lounge access unless you have a very long layover or arrive 5 hours before the flight. Inflight service was okay. But not up to par with the likes of QA, SQ or CX, even though the price is the same or even more. It was much better than the domestic flight where Lufthansa is actually a low-cost airline with legacy airline prices.

The seats on Lufthansa’s international business class on the A350-900 is the worst product in the market. Our chief purser was AMAZING though. She is the best FA I have had in many years.

One of the best airliner in the world But airport was very poor

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

the blanket was great and pillow helped. really need a toothpick packed with meals

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

Didn't have bar code on our phone based boarding pass. People at the counter didn't notice. We walked to security, couldn't get through, had to go back to check in to get a paper boarding pass.
