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. Oh and the seats were more comfortable, had more ability to lean and the headrest was much better for flight sleeping. 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.

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

The flight attendants should be nicer, on my first flight I told them I’d prefer a veggie meal sometimes and then she began to lecture me about it, it was a late flight and I wanted an easy digestion meal so that I can sleep quickly. The meals were abit odd, breakfast on my last flight had eggs, oatmeal and fish, did not taste good at all, strange combination. The economy seats are very tight and crowded, not comfortable at all. Overall for the price I paid I thought I was going to get more.

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.

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

Great service. Was there a food option? I was given food (I could have ordered ahead of time?) but had no choice. I like choice.

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

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.

Staff was so nice and very helpful with directions aswell!

It was our first time flying with China Airlines and had a very nice experience. The airline staff & crews both on the ground and air were very nice. Food on the plane was very good. Will recommend it to family and friends.

I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!

My ticket did not indication which group I was in for boarding; the gate attended help me

Very routh cabin crew food is only 2 meals for 13 hours fry with them They should get better training how to service good super routh language and talking with customer

I would like to commend the staff from this flight. They all looked happy and I can tell they love what they are doing and constantly smiling while serving the passengers. Special mention to the guy FA in our section. I did not get his name but he is so far the best F.A I have ever encountered!

staff are super nice and effiecient! It was a very comfortable and relaxing flight

Boarding could have been a little bit better but other than that it was a pretty good experience. I think because of the stowaway to Paris France recently they are being extra diligent about boarding passes at the gate. But they boarded the back of the plane first, and that's something I really think needs to start in the USA.

Didn't like on this return inbound flights (from Hong Kong to Vancouver) Outbound to the Hong Kong was good.

I was ordered vegetarian food, but didn't services to me :(

It was amazing. I was not expecting the phenomenal customer service Asiana provides.

It was all perfect and very pleasant for such long flights

The seats felt very small. We were supplied with pillows and blankets, which was nice. Lots of noise from the bathroom, plus exterior noise. Made it hard to hear the entertainment system, even using my own noise-cancelling headphones. The food was really bad. I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Two meals were served on this flight; one was a repeat of the meal I had had on the flight immediately preceding this one, which was bad enough I didn't even try it. Drinks were very limited. All I wanted was water, and on a 10.5 hour flight, I was given 3 cups of about 3 ounces each.

We took business class, It was comfortable and I was able to sleep.

For the most part, it was an enjoyable experience. It's the 2nd half of the journey was a bit uncomfortable. It was on a noticable smaller plane compared to the previous one.

Only process that my luggage didn’t make it to my destination because of short connection but I understand

The boarding process was good. The toilet could be better maintained.

This has been the worst experience I've ever had. We arrived to Ho Chi Minh Airport and were supposed to get our Asiana ticket from the transfer counter as we came with a different airline. However, the staff at the transfer counter were not helpful and kept giving us different information. We were first told by Asiana airlines staff we had to wait 2 hours so they could print out and give us our tickets, then someone else told us we had to wait 3hrs, someone told us "I don't know, just go sit and wait and we will tell you later." This was at a place in the Ho Chi Minh airport that had no coffee or food shops, nothing, just immigration (to enter Vietnam with a Vietnam Visa) and security (to transfer into the gates) but we needed our printed boarding pass to go through. It wasn't until we demanded to speak to a supervisor as our flight time was 1hr away because they kept telling us "there's alot of time left for your international flight, we will get your tickets later" we still had to wait around 20minutes for the "Supervisor" to give us our tickets. I would NOT recommend Asiana Airlines, especially if going thru Ho Chi Minh Airport as they are not helpful. (We almost missed our flight, due to their lazyness and incompetence of printing our tickets) I would suggest Asiana Airlines to have a Machine in the transfer area so passengers can easily print out their boarding passes themselves and save some money by not hiring incompetent staff that can't do a simple task such as printing a boarding pass.

Great service. They could offer vegetarian food and do more to reduce waste.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

Worst experience I have ever had with any airline in over 25 years.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

The flight was delayed for 30 mins. The overall experience was good.

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

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 -

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

bad… no veg food was provided eventhough i pre ordered special meal

I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

A bit rush for transit. Food and entertainment are not available

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

headphone jack didnt work for the first flight and not much variety

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Beijing PEK to SFO. I had an economy seat on this flight. The seat comfort was acceptable. My main complaint is with the FA’s lack of personality and absence from servicing the plane, specifically restroom care (I wish I could share a pic of the restroom that I captured) and care of travelers—drink cart/availability of drinks. I'm amazed at the level of service on other International travel where a passenger is most often appreciated.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.
