I have never heard of EVA air before but I am so happy my wife and I were able to flight on their planes twice. Everything on these flights just felt better than their competitors. As someone with longer legs any bit of extra leg spaces is appreciated. The different options for food and drinks were also a plus. They were extra careful to make sure my wife's eating restrictions were taken care for. They had a before take off and landing announcements on the built in tablets for each seat and it gave out information that was very helpful. Such as what and how to declare your items in the specific country you landed in, any odd items that may be illegal to bring it (and even the reasoning why) and any other information you might need to make your post flight experience better. The only downside was there were "forced" ads on the tablet at take off for maybe 5-10 minutes but honestly, this flight was the cheapest option and had all the benefits listed above that is such an easy trade off. Im keeping an eye out for EVA air going forward.

First time traveling with EVA.. great experience in economy class... Personnel very friendly..

Sub sandwhich for a snack through mid flight and giving a bottle water was a good idea

seats are pitched well. you don't feel too tight.

For the price, it was better than other airlines; quality of food and service was very good.

Movie selection was not as good as recent flights I've taken (EVA and other airlines).

I was sleep when they brought the food. They had put a note on my seat. There was no food when I asked for food later. There was just one main meal served in this 14 hours flight. They offered me sandwich with ham which I don’t eat since I am pescatarian. Long story short I had to wait to get to TPE to get something to eat. I am extremely disappointed from the service. I have been flying EVA since I was 1 year old. Perhaps no more EVA for me. Seems EVA glorious day is long gone

Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

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.

friendly and professional cabin staff... seems cold and a bit aloof...

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

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!

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.

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

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.

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

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

I was a member of Krisflyer for ten years, but my last flight to Tokyo was a disaster. I had to stand in line for four hours before check-in because they were late opening the counter, and there were more than 50 people behind me. The plane was extremely small, and the food could have been better. When I dropped off my stroller before boarding the plane, I expected to receive it upon exiting for my transfer. However, they returned the stroller to the checked baggage because they said I was late getting off the plane. Of course, I was late; they assigned me a seat at the back of the aircraft, and I was traveling with a baby! The worst part was when I arrived in Jakarta. They damaged my stroller and refused to approve my claim, so I had to pay for stroller rental because of the damage they caused. I don’t know what happened to Singapore Airlines, but I felt like I was flying with a budget airline.

Food option Hindu veg to Hindu non veg request was unheard

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.

The only thing that could have been better, is that the food trays get left way to long after a meal. We had a snack 8 hrs into the trip, and they left us with the boxes and cups for way too long. It is not fun being trapped in your seat unnecessarily

Worst air experience in whole life . Boarding and checking was hassle as they did 3 times. Crew team was clueless about passengers need. Despite of passengers raising hand , they were resetting the program

Overall good. Food choice in business class is a concern as same dishes on every flight for months. Crew is great and seats on this sector were fine . They need to have more variety in dining

The overall flight experience between Doha and Kolkata was satisfactory. The staff onboard were notably engaged, responsive, and enthusiastic, providing a level of service that stood out, especially when compared to the less attentive crew on the earlier leg from Heathrow to Doha. Their eagerness to assist made the journey more pleasant. Additionally, the time spent at the Silver Lounge in Doha contributed positively to the experience. The lounge offered a comfortable and relaxing environment, with adequate amenities and attentive staff. Overall, both the flight and the lounge experience in Doha met expectations, making for a smooth and satisfactory travel experience.

Moved seats, didn't accommodate requests to change seats even though other seats were available.

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Check in desk people constrained by fear. Obvious typo on Uganda visa, even though approved, caused loss of flight. Something is definitely wrong with this system.

Do I need to repeat my complaints about my lost carry on bag?

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

Better training for staff, I didn’t even get a napkin with my drink so it was dripping all over !

Fantastic! Great seats! Friendly staff! Amazing selection of shows and movies! Smooth ride! I don’t know what more I could have asked for honestly. They made flying a breeze this time around.

Had a very bad experience flying out of London. Our initial flight was cancelled without notice and the next flight had a layover of 8 extra hours. Me, my husband and my 8-year-old were already sick, and this further added to our problems. We paid extra for the seats: I was not even given our chosen seats which we paid for months before the trip. We were shoved into the available seats which were middle ones in the back (we had paid for front window, aisle, aisle). The seats were so uncomfortable and getting out of middle seats every so often (with a sick child) was a task. We had initially chosen British Airways because of the short layover, however, that went out of the window. Although unexpected things happen all the time and I understand customers have to adjust for the unplanned, however, how the airlines react and make the passengers comfortable during that time is the real test. We were not given any compensation for food or any arrangement to stay comfortable during that time. In fact, our paid seats were taken away as well.

The food could have been better. And the chicken sandwich was not nice at all.

Not the quality I was expecting from a company that has been around for ages and charges high prices

The whole experience was very disappointing. Drinks could have been served and offered more frequently. The seats were reasonable but considering I paid for premium economy, I felt cheated. I flew premium economy with Japanese Airlines ANA 5 years ago and their service was by far, superior. We had access to the club lounge, better seats and excellent service. Out of 10, I would rate the experience as 4. Everything felt cheap and the Airbus aircraft are far better and more comfortable

Hand bag was taken to be checked in at boarding gate

I couldn't get a vegan meal because I booked via kayak but everything else was lovely

Flight was okay however bags were left in London even though we had a 7 hour layover. Bags are yet to be confirmed to reach final destination. Horrible work.

Quiet and comfortable aircraft, pretty smooth flight. Very comfortable business class cabin with decent entertainment. Good service from the crew. All in all a good experience.
