The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

The staff were nice people, the food was very cheap, one of the meal was a sandwich or nothing, I couldn't buy any food, mind expensive duty free WAS available right away. 🤒

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.

I like how professional, fast and good the whole experience was.

For the price of the ticket it's probably the best service in the world

The plane was good - on time! But can the stewardesses smile or actually be nice - not to bark the commands

Lots of water brought around by staff which is very important to stay hydrated on a long flight. There provided swiss chocolate icecream! The attention to detail is obvious. They really want to make their passengers entertained and comfortable.

I would recommend flying SWISS to anyone. Very impressed by the quality of food. The staff was extremely kind and accommodating. They arranged a shuttle to help a group of passengers make connecting flights when there was a delay.

Flight was cancelled due to technical problems with the aircraft. It would be nice if SWISS would invest in new aircraft; that would for sure minimize the technical issues with (old) aircrafts.

overall the flight was good and we were happy they waited for us. However, our luggage didn t make it and this caused us a lot of problems.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Aircraft was spacious compared to American Airlines, food was great, entertainment was much better with a wide variety of options, and the crew was very polite.

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

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

Check in desk people constrained by fear. Obvious typo on Uganda visa, even though approved, caused loss of flight. Something is definitely wrong with this system.

Do I need to repeat my complaints about my lost carry on bag?

Being a platinum member, no attention given. No towel or tissue provided.

As gold member there is no priority checkin. Meaning you either have to board with your zone or last with business class pax. As economy pax all the baggage bays are filled by the time you arrive

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

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.

Should have had business class line in immigration. Food quality suboptimal

Likes: on time departure, new plane Didn’t like:very poor quality food, very limited entertainment.no amenity kit etc.

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

The flight was delayed which cause me to miss my connecting flight in AbuDhsbi airport.

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

I recently flew with Turkish Airlines, and I can confidently say it was one of the best travel experiences I’ve ever had. From the moment I boarded, the crew was incredibly attentive, warm, and professional. They went above and beyond to ensure everyone was comfortable and well taken care of throughout the flight. The highlight, however, was the food! I’ve flown with many airlines, but Turkish Airlines sets the bar incredibly high when it comes to in-flight dining. Every meal was fresh, flavorful, and beautifully presented. The variety of dishes, even on a long-haul flight, was impressive. It felt like dining at a high-end restaurant at 35,000 feet! The seats were comfortable, the entertainment options were great, and the overall atmosphere made the journey enjoyable. Turkish Airlines truly excels in combining luxury and hospitality. I wouldn’t hesitate to fly with them again—highly recommend!

The Etickets had been changed (Why?) without notice ; Hence, that caused troubles when checking in. Not until I contacted my ticket agent and was given correct Etickets could I then check in.

While we were picking up passengers in São Paulo, on our way from Buenos Aires to Istanbul, it was impossible to use the bathrooms for 90 minutes. The crew was largely inattentive with one or two exceptions. They should distribute more water for a flight that long. When I signal that I wanted to have a second glass of wine, my prayers were left unanswered…

One of the best flights I have been on in a while. Food was excellent. The chair-back screens in economy were A+. The crew was friendly and helpful.

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.

The WiFi setup on the plane is needlessly cumbersome. Simplify the interface and login.

I liked the ability to walk and stand in the crew area. I hated the security check experience before boarding. The airport staff were so rude, yelling at us unnecessarily, delaying us on purpose, and even threatening to call the police on us!

Internet connection was very weak, did not connect at all. Seat comfort was poor, buttons didn't work properly. Overall not impressed in business class.

The plane is cramped and there is no space to move. The seats should not recline because when a person in front drops their seat you are trapped and you can't even see the entertainment screen because it is right in front of your face. I like that checked luggage is included. The food tasted good but they ran out of breakfast choices. The crew is nice.

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

No entertainment since it was a 3 hr flight. Good leg room for economy.

For such long flight we were expecting more comfortable seat , which were to close to each other , the backrest we could only lean a few inches to the back and you really couldn't stretch your legs.

This is my second time to fly this year with Lufthansa and both times they dropped the ball. My ticket was very cheap and l would not be honest if l said that l had some high expectations for that price. Fly delay 6 hours. Screen in fey seats around me didn’t work. Food for dinner was ok but breakfast was so poor. We had connection in Frankfurt for Vienna. Because of delay they gave us fly with 30 min layover time. We got to Vienna but our baggage was late of course. Long story short it took us almost 24 hours to get to the final destination. Very bad experience

Professional crew and staff, very organized boarding and on time flights, baggage handling. Indian vegetarian meals were good, though could improve by offering Indian bread (naan/paratha/roti) as well. Very helpful pre flight emails with details of onboard experience 👍 Above average selection of movies. Consider offering more movies with subtitles and ratings indicators (e.g., IMDB scores).

There was more leg room than on the overseas flight, which was nice. Boarding was very well organized and the flight very comfortable.

The flight to Frankfurt was delayed. Consequently the connecting flight to Seattle could not be boarded. Lufthansa accommodated in a Cattle Class Flight where the Seats and foods were horrible. I had only Hobson’s Choice and boarded the flight and reached Seattle 3hours later than my scheduled arrival.

No Wi-Fi or food unless you pay an expensive fee.

Not good. They charged an additional $70 to check a bag we had already paid for on line with Lufstansa

The plane was clean and the staff professional and courteous, as usual. The seat back was very hard and uncomfortable.
