First time and very memorable, the finest flying experience ive ever had

It was great, a little more leg room would have been better particularly since we were in premium economy

Boarding, seats, entertainment and service were all great. Food was great except for the fact that there were too many sweet items.

Poor flight aircraft very old Crew was friendly 1 person though

Amazing and great experience, crew was available and took great care of my parents. Food was nice and so was the service. Aircraft from Dubai to Mumbai was not so great and was a big showdown of the aircraft service

The entire crew was amazing. They went out of their way to make us enjoy a great travel experience.

Loved everything! This flight had premium economy and I didn't see an option to upgraded to premium economy OR buy premium economy tickets. How come?

Better boarding process at Hyderabad airport Better time management by air hostesses in providing the meals

The flight was nice and on time. The comfort can be slightly better in business class

Okish. But for £550 , I’d have preferred a better experience

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".

I recently travelled in Business Class with Qatar Airways, and overall, it was a pleasant experience. The cabin crew stood out for their kindness and professionalism, making the journey truly comfortable. The food exceeded expectations and was exceptional in both quality and presentation. The boarding staff was courteous, though I would like to mention that the staff member responsible for checking tickets during boarding could benefit from additional training to be more welcoming. A warm and hospitable approach would enhance the passenger experience significantly. However, one aspect of the journey was particularly frustrating. The in-flight entertainment system was disappointing, as the headphones provided did not work at all due to a loose connection. This significantly impacted the experience, especially since the flight also lacked Wi-Fi service. Addressing these issues would greatly enhance the overall travel experience. Lastly, I would suggest implementing a section-wise boarding process to streamline the boarding experience and minimise potential challenges. I appreciate the efforts Qatar Airways puts into delivering high-quality service and hope to see these improvements implemented in the future.

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

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.

There was not enough food for everybody. Some dishes were missing.

Qatar Airways in-flight first/business class service is superior to any US airline; excellent meals are served on short haul flights such as between DXB and DOH.

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

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.

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.

Took a long time for boarding. The flight was comfortable.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

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

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

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

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

The segment bkk ist was ok. The segment ist to yul the boarding was chaotic with 5 control before get in the plain, in addition to normal control by scanner and metal detector during transfert

The flight was great. From the first to the last step, the staff was very helpful and understanding. I also always enjoy Turkish Airlines food because it’s flavorful, fresh (like salads and very delicious bread ) and has special things like olives, dates… I loved that bean salad and apricot pie. I also enjoyed the movies. Thank you!

Very nice and friendly crew. Boarding system can be improved.

"I had a fantastic experience with Turkish Airlines! Here are some things that really stood out to me: - Delicious food options, including a wide range of Turkish cuisine - Friendly and attentive flight attendants - Extensive in-flight entertainment options - Smooth and efficient check-in and boarding process Overall, I was thoroughly impressed with Turkish Airlines and would definitely fly with them again. The combination of comfort, service, and amenities made for a truly enjoyable flight experience."

In this long haul flight, flight attendants never stopped moving and giving excellent service. Very impressive. Very comfortable seats and excellent food

I felt the AVM was bad. They could have done better and felt the route was much long theb expected otherwise it was good experience.

Vegan food tasted good. Restroom could be kept cleaner. Seat tray table was a bit tilted so food tray kept sliding down a bit. Flight crew can be a little more friendly, caring and approachable. Their faces lacked smiles and tone was stern.

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.

Terrible boarding process, no proper line maintained even for business class, crews are not very attentive, business class food quality / variety / quantity have gone down, everything has become cheap.

It was very good and it was not my first time I always take Turkish air line for my travels

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

The crew were excellent, service amazing, blankets and pillow good, cabin temperature perfect, the flight on time, food was unusual selection however plentiful, price for tickets unbeatable through Kayak. Older aeroplanes used by China Eastern was the only down side.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

The temperature of the plane cabin is too hot. Sweat and uncomfortable. Also my food tray was broken down drinks fall off

Reasonable. What they offer during the flight is not great, but the crew is polite and try to compensate it.

Price is the main attraction. Staff is OK but difficult to communicate with them due to general lack of English. Food is truly abysmal, the main courses (4) were barely edible. The choices for breakfast served at 5:30 am prior to landing at Gatwick airport were Spaghetti Bolognese or seafood fried rice. Choices offered for all 4 mains were either something rice or noodles. Shanghai airport layover is much too long in a very poorly serviced airport. We were unable to use WiFi; private lounges required cash only payment with no ATM or cash exchange open.

I was surprised and appreciate that they actually served a hot meal on such a short, early morning flight. The check in and boarding was hassle free and most of all my Alliance Status / Code Share was recognized and the revelant courtesy was extended; other than some needed attention to detail concerning the cleanliness of the cabin, and some unnecessary aggressive wording their safety briefing, it was an overall pleasant flight, and I would certainly fly with them again.
