The boarding was organized and efficient. The crew was very thoughtful and did not wake me up when meals were served. I was totally exhausted after 2 weeks of vacation with a tour group. So sleep was more important to me. The crew just left me a sticker telling me that food had been served and if I woke up hungry to contact the crew. I did have the last meal scheduled on board. Food was very mediocre. The scrambled egg and minced meat were too salty. The porridge was passable. I was disappointed because I have high expectations of food from Taiwan. I thought EVA being a Taiwan based airline would have served its customers better tasting food.

The food is quite mediocre. I had spaghetti and the tomato based sauce was quite salty and there were no other flavors, no spices used in the sauce.

Except for crying babies all was ok although the movie selection wasn't the best.

Good. Please add a non- applicable category to your questions.

The staff was marvelous. The entertainment options were terrible, old or 2nd rate movies. I was unable to entertain myself for 18 hours-it made it seem even longer. Note: I thought about upgrading but your information about what was included was unclear. Are the seats bigger? Are there current moves? What kind of food do you get? Would the upgrade compare to Delta? Just saying the upgrade is better didn’t convince me and I regret not flying Delta.

Crew's attitude can be better. I asked one crew member to help to put carry on baggage into overhead bin, but he was not willing to help. I needed help because my height is short. His attitude was bad.

On time service. Seat comfort and the crew service very good .

I like Eva Air. I’ve been flying it for several years.. I did notice small changes for the worse by the staff. They’re still way above major carriers based in the USA.

I was expecting that movie selection and food would have been better. Everything else was great.

Great experience for a long 13-14 hours flight. Great pilot and crew, everyone is pleasant and attentive to the passengers.

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.

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

Service on board was excellent. Flight attendant was very helpful. I wish the website is more functional. I can't even choose seats online and had to call the customer service. During check-in at the counter in CGK, I saw a printed page about paying for the bulkhead and exit row seats, so I asked the staff at the check-in counter. I was told that the flight is full and there isn't any seats available for paid upgrade. When I boarded the plane, I saw so many bulkhead and exit row seats empty and asked the flight attendant. He allowed me to purchase the upgrades on board. It would have been nice if I could purchase the upgrades ahead of time, eg. During online check-in or bag drop at the airport. The economy seats in the A350-900 are arranged in 3-3-3 configuration. Seat width is a bit tight for me.

Overall things were very good and orderly. The food was very good but I want able to get a second drink very easily, so that could have been better for services. The seats seemed to be lacking legroom but I'm also 6'1" so I'm used to wanting more legroom but the plane seemed smaller then others when it came to legroom. My kids all enjoyed the entertainment as did I so that was perfect!

The flight attendants ignored us several times which was annoying. The sandwich thing wasn't very good but it's only an hour flight, it would have been better to have entertainment over bad food.

It was good overall. At 6 foot 1 it's hard to say anything seat on a flight is comfortable but it would be nice to have more legroom. The meals were good but would have liked to get wine much sooner.
