Sichuan Airlines was surprisingly great. The crew is fabulous, the plane was fantastic and nice and new (A350-900). I had a particularly nice flight attendant who kept me informed of all the flight progress and meals. I also got to sleep really well. Entertainment and food is more tailored to majority (Chinese) so I can’t really complain about that. Overall fantastic flight!

Sichuan Airlines was surprisingly great. The crew is fabulous, the plane was fantastic and nice and new (A350-900). I had a particularly nice flight attendant who kept me informed of all the flight progress and meals. I also got to sleep really well. Entertainment and food is more tailored to majority (Chinese) so I can’t really complain about that. Overall fantastic flight!

Very old business class seats, not fully flat, angled with a bar sticking in your back; seats old and apparently never cleaned, no mattress topper either, not the standard expected in J (also in awful 2-2-2 layout)! Ancient entertainment system of the pop-out type with tiny, old screen. Staff are OK but not proactive, need to be solicited, and of limited English skills, but they do try. Food and beverage options very limited (go for Chinese selection as their Western food is atrocious), no menu given and no dine-on-demand option. All in all, only choose if at a significant discount.

Definitely not top-of-the-range business class, but the A350 is certainly better than their other planes which feature an even older business class. Food/drink offerings are very limited and not up to business class standard, but OK. Staff are keen to help and friendly enough, although poor English language skills. Boarding experience in Rome was poor due to rude Italian staff at gate, but this is not the airline's fault. Onboard entertainment options are mediocre and limited. Sichuan Air is only wort it when obtained at low price and if you basically only want to sleep/rest and bring your own entertainment.

Not sure who to "blame" but I booked the ticket from SiChuan airline overseas. On the day of flight at the airport, I learnt that our passport information was not entered into the system. I was told by the SiChuan airline that this is not the first time that ticket booked overseas missing ID information. Since airport ticket counter does not have authority to add ID information, we have to call SiChuan airline customer service, Luckily, we arrived at the airport early enough to handle this and SiChuan airline customer service has been very helpful.

Dad experience when you check in in chenddu airport , service need to improve

Not good experience when you checkin in China, service need to prove

Gate and boarding processes were handled smoothly and efficiently. Both (connecting) flights departed and arrived on time. The cabin crew seemed anxious and a bit stressed/rushed. Food service was OK, but the hot food dishes were poor quality.

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.

Food isn’t hot, seat is too tight even for a person weight 120 lbs.

Flight was delayed due to air traffic control and technical issues - power outage happened several time during taxiing in Taipei causing further delay for urgent technical check.

For an international flight, the service was average at best. It could have been significantly better, particularly with regard to the food quality and options. Additionally, having only two restrooms available for the entire Economy Class made the experience less comfortable and resulted in long wait times.

I spent 45 minutes with supervisor trying to get 2 bags checked for this international flight . He wouldn’t give it to me because West Jet was involved in this booking.

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.

The crew and the food were excellent. The plane was kept quite clean.

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

I love the comfortable business class seats. The service was excellent. Staff was friendly.

After each meal was served I didn't see any flight attendant offer coffee or tea to the passengers after the initial drinks were offered. Other flights I had been one it was standard procedure to offer hot drinks after the meal service.

Food no choice just give it seams trying to finish what ever you have in hand

The crews were very professional and courteous. Pleasant flight and thank you!

They wouldn't let me on the plane. The 3rd party apparently didn't pay for the tickets properly?

Overall experience is good but if the food menu can change to authentic Malaysia food will be good. I.e. Nasi Lemak, Char Kueh Tiew and etc

Surprised that the safety briefing was only conducted in Malay language and no English despite there are foreigners on board. MH should take safety more seriously.

Flights were delayed, Food was good but only 1 meal instead of 2.

Food was good but only 1 meal and 1 pie, instead of 2 meals. Both legs were late.

We are row 11, when the crew came to us, only one meal choice was available.

OK seats comfortable, easy boarding/embarking, excellent connection to domestic Malaysia flight with baggage checked through without customs. Catering especially drinks borderline ok luckily less important aspect

Comfortable seats in economy, managed a few hours sleep in an o night flight but the food was terrible. Surprising as Malaysia airlines has been good in the past. Service was mediocre this time too.

Very comfortable flight. I appreciate the announcements were also in English.

Very poor experience. The entertainment screen wasn't working, charging USB was not working. There was a water leak on my head from air conditioning. The tray table was cracked. seats were old and dirty.

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

The boarding experience was very organized and easy to follow. The flight was pleasant and the food provided was also very good. Both Delhi and Mumbai airport have metro connections which make getting around much easier.

There’s no comparison for new avatar of air India. Long live Air India. Amazing hospitality and ultra soft polite charming crew

Overall it was good. But air planes should be upgraded.

my experience with kayak was terrible. Team kayak just left me with a booking and limbo and preffered not to contact me.. Instead when I contacted the team they said the booking is cancelled. Seriously 5 days after booking u were waiting of my call to inform me of the incompetence of the team. This will be taken up with higher authorities

Boarding was through bus even though aerobridges were empty. Major mess

Uneventful trip. Good flight crew. Food could have been better and a bit more of it. Cabin cleanliness was ok.

Too many changes in departure time (4-5 times before the actual departure time was determined) with no reasons provided.
