Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

The seat in economy class and legroom in Singapore airline are narrower than Korean airlines! I don’t have that comforting feeling flying with Singapore air as in the past!

It was very good experience on board to Sydney with SQ.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

The food options and quality could use some more excitement and variety.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Really enjoyed the flight. Our flight attendant on the way back SIN-LAX was exceptional I didn’t get her name but she was so kind and went above and beyond to make sure I was comfortable. I had a bit of a panic attack and she checked on me a few times to make sure I was ok. Really appreciated her attention and service. Thank u

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

The setting configuration of the aircraft stinks. Nobody should pay business class fares and be so uncomfortable. The design of facing fellow passengers is a brilliant nincompoop.

Entertainment is limited with a relatively old catalogue. Wi-Fi never works and the cabin and lavatory had evidence of a lot of scuff marks and temporary repairs. Nothing unsafe, but a bit tatty in places.

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

USB charging port was not working at my seat 48K.

I enjoy flying with Thai Airways, however their B788 business class configuration is quite dated. Additionally , while the service is always friendly and efficient, I’m getting tired of the same “usual suspects” when it comes to food choices. Since it was a lunchtime flight, what about some gourmet sandwiches or some type of salad dish for the main course? The entertainment options are also quite limited and this is not unique to TG, so much so that given the short duration of the flight I ended up not bothering with any entertainment. Finally, despite signs around the cabin advising wifi available, I was unable to con-net and in fact I’ve never been able to connect on any TG flight over the last year or so - what’s the go here??

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

Delayed QF59 flight once again, Qantas doesn't fail in maintaining there delayed departures and arrivals. USB points do not work nor do the power point sockets on the plane, Qantas staff admitted that on the flight. Don't expect to your charge devices. Saving grace, was the ice cream. Bottom line, if you expect to fly to HND and make it on time avoid Qantas and if you're interested in ice cream - visit 7/11.

Pretty excellent. I don’t know what the pilot could have done better with the bumping ( there was a storm) nor what happened to my ears coming down into bendigo. It doesn’t happen coming down into Sydney just the return flight. I wonder why?

Loved the staff. The economy seats could have been bigger.

Airport and crew experience was excellent. We had to queue for the runway - no one’s fault, but it did mean we were 30 minutes late leaving

Overall good experience with flight and airport wheelchair staff. Also got Indian food in the flights

I liked the service, the menu, and the comfort of the seats! Even tho we were seated by the bathrooms, the reclining seats and movie selection was very good, my husband and I didn’t mind at all

Very good as always, stand out airline. The passengers whom choose to stuff baggage that otherwise should be checked-in is a real bother but that's not the airlines doing. A real frustration that passengers just don't want to check-in luggage. This is a pet hate unfortunately.

It’s a two prop flight so I had problems with my ears on re- entering ! But otherwise fine

I love flying with Qantas. There was no onscreen entertaining on this flight, and only a snack provided (not a meal) but still better than Jetstar or Virgin (in my opinion) so still happy.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

stuck in the aircraft for over three hours due to engineering work, significantly delayed and made a lot of passengers missed the connecting transport, no mention any compensation

Very quiet plane!! One of the quietest planes we have been on.

Jetsatar refused to take my foldable stroller in the plane, despite following all the rules on dimensions and packaging. Similar thing happened on our previous fight. However, at that instance, they offered to check in the stroller. At this fight, the staff was rude, trying to rush us to board the flight. They made excuses that the stroller was not allowed and even offer to leave it behind and ship it back at our own cost. Fortunately, we had someone else attending. Since the flight was about to take off, they left it behind and send it back to us on the next available flight.

Overall, it was good. The only concern was that I couldn't charge my phone because the USB port didn't work after we took off. One of the crew members tried to restart it but never came back to me with an update.

Comfortable seats, boarding was easy and staff were very nice.

Flight was fine but a domestic flight was called by Jetstar international. This meant going through immigration and custom scanning twice. Long queues were experienced which were frustrating. We were using a wheelchair and exit at Perth needed a scissor lift as no air bridge provided. No fast lane at Perth for wheelchair. The staff were helpful but this system is poor.

The crew were great. The seat was older than an old Holden with a big metal bar sticking right into my back. The passenger next to me complained that hers was the same. The pre purchase system for food was disappointing as the pie/quiche took 20 mins to warm up, arrived too hot and with no utensils. It was one of the most uncomfortable flights I've ever been on.

Not very good, no food and not drink ( caffe or tea). Never ever fly with jet star.

Fabulous I have no issues with JetStar great service always use them to fly

Flight was as expected - we got what we paid for which was a base fare

The flight on the 8.10was canceld so i had to by tickt on anather airline As the low say i will need a full refand of the mony i paid you for this flight! Thenk you Dan richental

No snacks meal or drinks for 9hr flight, no entertainment options. Crew appeared tired, irritable. It's apparently a budget airline, they make sure it feels that way.

Un peu déçu par le vol, c’est la première fois que je prend un vol de 6h ou les boissons et la nourriture sont payantes et pas inclus dans le vol. Peut être que c’est propre à la compagnie mais ça m’a surprise. Le fait qu’il n’y est pas d’écran pour pouvoir passer le temps était aussi un point négatif. Cependant le personnel était très agréable.

First time of flying with Air Asia and great choice

Don't even offer water on a 5 and half hours flight. Its laughable one have to rent a blanket.

No free water. Water cost money in a currency that I didn’t have.

Pay for food on an almost 6 hour flight. Very tight space, I had to show my boarding pass for the food I paid and the blanket set. I had an online boarding pass, that didn’t work, I had to take out the printed boarding pass out of the overhead locker whilst my neighbour was eating, as I was sitting in a Center seat. The staff was very friendly and got my bag out but it didn’t make sense. As the online boarding pass was enough for the blanket set. But not for the food. Just to make a check on the piece of paper. I had a warm free meal on an one hour flight from BKK to Samui with Bangkok airways. So airasia just tries to save money where they can.

Pros: "The flight got me to where I was going."
Cons: "If you are.looking for some entertainment for a long flight, there will not be any."
