Never book through Kayak. They can offload booking to third parties that are completely horrible.

Never book through Kayak. They can offload booking to third parties that are completely horrible.

It was okay. I feel that Singapore Airlines isn't as good as it used to be but it's still not bad

Crew is excellent Wifi needs to be improved in order to connect to the internet.

Excellent crew service. Professional, courteous. Service with a smile. Good food Very decent flight experience

Service was very good, food and entertainment systems were good

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

toilets could be cleaned more frequently, everything else was pretty good.

The crew was very courteous and professional. the flight is relatively clean and comfortable.

Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available

a completely full flight - felt quite carmped in, despite being on the window seat. Meal served could better. Surely different from pre-covid trips I used to take to and from Bangkok.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Excellent airline. The plane was clean and the staff were very attentive

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

I do not think there was much that could have been done to make it better. The delayed flight was due to bad weather. The turbulent patches were very unavoidable. Am simply thankful that there were no sudden and / or sharp drops during the flight. I do extend my compliments to captain Marcus I believe was his name and the rest of the crew. They all did an excellent job. My only question is whether I get a refund since the seats I had chosen and paid for were reassigned.

Missed our flight with Cathay due to late Westjet plane and chaotic Toronto airport. Had to clear customs get bags and re check bags in an hour. Did not make it got lost not clear signage with bag drop off. West jet only allowed 1 checked bag for this international fluid. Cathay checked my second bag for free.

Flight was kept super cold. I was shivering and had to layer up.

More meal choice. There was only pork, beef and shrimp. I could not eat any of it and they had no alternatives

Crew were not engaging. Only engaged if requested. Food taste was mediocre

More tasty food particularly ethnic food. Staff didn’t respond to calls some of the time in premium economy.

Great. We received a meal even though it was a short flight.

Boarding on any airline is a hot mess. Load your pivilaged passengers, then back to front. Back to front.

Multiple late or canceled flights. Lounge was 100 degrees. Food was terrible. The plane was incredibly old, and best of all, a screaming child for 3 hours. All for the low low price of $2,600 one way Hanoi to Shanghai. No idea how Cathay is ranked so high. Cathay is not much better than American Airlines or Spirit. In the future I will go out of my way to not fly Cathay.

I liked the service. The touch screen needs improvement as well as movie choices.

My journey with Qatar Airways from Ahmedabad to Jacksonville on 3rd February 2026 was truly exceptional. The entire experience reflected comfort, care, and world-class service. Complimentary high-quality Wi-Fi throughout the journey was a welcome luxury, especially on a long-haul flight. The vegetarian meals were thoughtfully prepared, delicious, and served with attention to detail, along with a fine selection of snacks and beverages. What truly elevated the experience was the cabin crew — graceful, courteous, and genuinely attentive, delivering outstanding hospitality at every step. This journey perfectly showcased the premium standard Qatar Airways is known for, and it left a lasting impression. I would gladly fly with them again.

Top, only problem about Weather but not depended Qatar Airways. Anyway staff offered kimbo Refreshments

Impressive as always. It is the airline of my choice, The dessert on the 2nd flight DOH-IAH was somewhat dry (the cake with cream etc) Check-in and boarding experience was fantastic, with the exception of CCU airport where chk-in staff refused to help with aisle seats stating the flight was full and accommodations were beyond him. Once I boarded there were plenty of available aisles. I was disappointed that this could not be done by self during online chk-in nor at the airport. Nothing more to add. Overall a good experience, TY QTR

The boarding process was awful-the computers were down and there was no way to check in. Took extremely long, very chaotic and no guarantee our bags were even getting on the plane. I was also delayed and took away from any time i had to catch a connecting flight.

This flight was a very good trip for us. The crew were very friendly and helpful. They made arrangements for my husband to have assistance in boarding. We were not expecting a meal, so it was a pleasant surprise on this short flight to have a meal and beverage from a very courteous crew.

I am a big person and have back pain and swelling in my legs, so this was a challenging flight due to confined space. I didn't find the crew very friendly either. I will think twice before flying long distances with Qatar again, due to the lack of legroom.

The service was good but the food was a NO

Excellent service. The personal adaptation of menus and the individual timing of service of them is fantastic.

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

1 hour delay meant missed my connecting flight and 1st day of holiday

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

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

Ethiad wanted to charge me $1100 for 2 checked bags on a ticket that was $550. Nother the airline or airfare assist was willing to help before arriving at the airport. All parties said it was the other responsibility to help. Never flying ethiad or using kayak again.

It was great! Kept the time. Provided what was promised

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

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

The flight was over 1 hour late taking off ,when I arrived in Abu Dhabi ,I missed my connecting flight to Bangkok so I had to wait almost 6 hours for my flight arriving in Bangkok at 6:30 am ,So I missed a whole day of my vacation and my hotel room sat empty so I paid for hotel days that I was not there. In Abu Dhabi there was a woman that worked the desk at transfers that was so professional, courteous , helpful,and may I say absolutely beautiful .she got me food vouchers for my layover and was a very calming presence. Besides that I will never use Etihad again I will pay the Xtra money . I'm sure they won't read or see this but it's my "2 cents" I'll use an airline that respects me and my hard earned dollars

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.
