Great to have actual hot tastey meal on a flight. Well done

All in all the flight was good. Love the fact that for airline food it was piping hot

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

Wonderful service, planes and interior in great condition, very pleasant experience

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

The stewardess was very helpful all the way. My seat had an issue with headphones and after the replaced and gave me a new pair and noticed it was the seat I got a new chair to sit and a great ride back home

The seat comfort, the food and of course the crew, they made you feel welcome and relaxed 😊

The overall operation needs to be improved. The in-flight services took forever and sometimes ran out of options.

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 ;-)

No towels or tissue and chocolate and mint provided before arrival

Not good. Expected a lot more as far as excellence.

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

Fantastic, the 787-9 is a very beautifully designed plane and it was a pleasure to fly in the Qsuite. The suite did feel slightly smaller than the 777 variant, and the suite door also felt smaller, as I felt more exposed as passengers and crew walked past. Food was too notch, and the service was fantastic. I wish they’d enforce boarding zones more effectively, but otherwise they did really well.

To many ads. 3 or 4 between each movie. All repetitive, all related to Doha which I was just passing thru.

My seat that I booked over a year ago and some other passenger was sitting in it. They said they could not walk and they would not move. I was with my young kid and the crew did nothing to accommodate that. Just disappointed that the airline accepts that excuse from a passenger.

Crews are very rude and unhelpful. Cramped seats in economy. Foods are useless

Better service is needed. I booked for Qatar but I was switched to American way after I bought my tickets.

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

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

In my opinion, Etihad Airways is a first rate airline except for one important element. On the day before my return flights, when I chose my seats on the Etihad website I was charged an additional $55 (US) in order to sit on the aisle. I was not at all happy about this additional "hidden" charge and I felt cheated.

My wife and I were upgraded to Business Class on our Dublin-Abu-Dhabi flight on the 22nd of January. Being served by "Mariyan" (not too sure about her name, she's from Tunisia) was the real highlight of our flight, she deserves to be working with etihad. We are looking forward to the next upgrade as we are flying back to Dublin on February 01, 2024. If I am not mistaken we have just reached GOLD status as Etihad Guests.

Eine Toilette der Business Class war gesperrt und somit nicht benutzbar.

Crew was good, boarding mediocre, food choices were limited, seating was not comfortable

Everything is good and improved and needs to improve economy class seat more specious so long journey we can enjoy and it will be give more relaxable. Overall all services good and safely landed . I enjoyed my journey and all the cabin crew members services very well.

Sits are very uncomfortable and food quality should be improved. Alcohol you have to ask and wait for more then 1/2 hrs. Don’t feel like to travel in Etihad. It was 1st time we traveled in Etihad now we decided we don’t want to travel in Etihad.

Very very bad service very tight seats never ever flying with Etihad again

Check in was quick and gentleman was very nice and friendly, during flight crew members were polite and attentive, food wasn’t as it should’ve been. Entertainment section needed to be updated i.e add new movies

Next time im going to use Kuwait air lines, hopefully

Comfortable seats. Be aware there is no alcohol on this airline.

Seats were comfortable. Be aware there is no alcohol on this airline.

Every thing was very food except the meal. It was a sandwich of something like a beef kebab. It was really bad in terms of hardness as well as taste. We were a family of 7 persons non of us could eat it his sandwich. Cake was good.

It was very nice flight only suggestions to upload recent videos and English subtitles. Thanks

Wheelchair service is not available right away on Kuwait Airways

Everybody was so nice to treat me good all the workers When I came to Bangladesh there was just a little problem with the luggage but I got my luggage it took like two hours Other than that everything is good

Food quality should be upgrade. Plastic spoons looks like not good as well as food quality not up to the mark.

Everything was great specially the seats was comfortable even I was in the economy and the food was really Great👍

Not much on entertainment, food was good but not delicious, flight was on time

The flight was delayed for almost 5 hours, but I understand that it was not up to the company, however how they could handle the situation better, they never apologized for that delay, moreover despite passengers being there for 7 hours only thing they did was to give a bowl of instant noodles, afterwards on the plane tiny snacks, people were there starting from lunch time and we’ve arrived to destination at almost midnight

Flight was delayed for 2 hours for no reason, then we spent almost an hour after boarding because of the weather conditions. If we left on time we could avoid that 😾

Pros: "Friendly crew and helpful staff"
Cons: "Missed connection from PEK to XIY due to delayed arrival and early departure. From XIY to PEK, booked and confirmed 11 departure, changed to 12:30 without notification or explaination. Rushed connections at PEK, pretty much ran from the minute left plan to another terminal, through custom, through all the health check points, security check. Just keep the fights on time and keep the original schedules, not arbitrarily change them."
Pros: "Because of our delay, we flew with Air Thai instead of Air China....much better airline"
Pros: "The crew was accommodating during the flight but spoke very little English and could not help with information on connecting flight."
Cons: "We missed our connecting flight due to a delay and the airline would not let us through because we could have made our second flight...."
Pros: "The price"
Cons: "Staff was not helpful and kind of rude unless you spoke their language. Food options were terrible and not very comfortable seat for 13+ hr flight."
Cons: "Seats are narrow, leg room limited, and food is minimal."
Pros: "The crew was super helpful and amazing! Comfortable seats and plenty of space for someone my size to sit (5’4”)."
Cons: "The only thing that I think could be better is the entertainment. I had a hard time figuring out how to use the screen on the aircraft but the selection of shows was good."
Cons: "Really old aircraft...please upgrade the video systems and make sure everyone has the same good optons"
Pros: "Boarding process may have been the best thing possible."
Cons: "Customer service could be a whole lot better. Seats very uncomfortable for extended flights."
