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

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

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

Everything was great keep up the good work 😁, can't ask for more.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

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

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

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.

very professional and very attentive to my Special Needs as I required a Wheel Chair and assistance to board

Crew was great. But a bit understaffed. The business class seat, etc were dated. But comfortable. Some legs had entertainment system from a decade ago. Selections were rather poor. Food was mediocre at best. Actually poor for business class standards. I liked the lounge in Hong Kong. Showers were great. Food was nice.

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

Everything was fine and I have no complaints or things to note.

Overall, it was ok. However, the food was very sub-par.

The economy seats are much indeed roomier. Meals needs improvement.

It was okay overall but the food was very, very bad.

When comes to Taiwan airlines China airlines is the best rest are pure trash

flight delayed 45 mins - missed connection - 1 hr layover became 8 hr layover waiting for next flight -

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The connection between LA and Atlanta was too much stress

Terrible boarding experience,,food is very poor that I I . Never going book this airline again.

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

Not good - chair back could not move back for premium economy. Not worth the price

The back of the chair - premium economy could not move back - not worth the price

It was okay. Boarding the staff made you feel rushed like we were late or something

It was great. The staff were so nice and helpful the food was great and they always made sure I was okay. As a foreigner I was worried about the language barrier but it was absolutely no issues. I highly recommend

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

Food is good, staff is good... Wi-fi quality is poor, disembarkment after landing is atrocious.

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.

Terrible. Air India canceled my flight out of Kathmandu because of airport constructions but did not tell me. They should not be selling night flights out of Kathmandu right now that they know they will not honor. The staff was terrible and not helpful with my rebooking or compensating me.

Good experience, comfortable seats. Entertainment did not work but vista wifi and entertainment worked great.

Flight leg to and from IAD/Delhi was good. The leg to and from Delhi/KTM was terrible.

The aircraft interiors are falling apart. Felt like a waste paying for business class as it was indistinguishable from economy in any way.

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

Ok, where do I start, hmm! Good things first - the meals/food was tasty, the seats are comfortable and legroom in Economy was ample and foot rest with message roller is simply amazing, Wi-Fi Entertainment works well. Bad things - in-flight entertainment screens and remotes either had physical damage and or simply not working. This was the case for more than 1/2 the flight. Flight that was long haul - 12+hrs non-stop. If you want a cracker or a biscuit with your tea - forget it, they carry none. Feel like having a chilled beer - forget it as they will serve you room temperature always and every time. The crew seem young and inexperienced. Will I fly again, yes I would only because it gets me from Sydney to Delhi in 12.5 odd hours (fastest), otherwise I will never. It has been what a year or so since TATA took over but I have not seen any change, I really hope this changes.
