The food from Los Angeles to Taipei made me throw up. The flight is also not comfort. But the staffs are very friendly and nice.

The food from Los Angeles to Taipei made me throw up. The flight is also not comfort. But the staffs are very friendly and nice.

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.

I appreciate the email reminders for online check-in which made my entry to the lines less stressful. The flight was on schedule and on time. The baording staff were proactively helpful and approachable. The airplane inflight food, entertainment and comfies as well as provisions are excellent even in the economy seating. The airline transfer was smooth and easy! Luggage safe and intact! Thank you EVA airline for making my trip a reliable safe and comfortable experience.

Very smooth flight. Superb crew, great food and service. Slept most of the way. Excellent airline.

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

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.

delayed and the cabin crew was like trainees.. a bit careless and not so pleasing to their job

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

The app was awful. No accurate info. Paying for internet is a negative (Delta is free). The crew was very nice for the most part although you are not guaranteed to get good service. Some crew would ignore requests for things as simple as a cup of water if you were sleeping when the first serving was made. Food was great. Male crew member was exceptionally kind and responsive.

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.

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

Not many people, so you can lay down on two seats

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

Flight delayed going to Korea. No free WiFi. Other than that everything else is were good. I would love to fly with Korea airline again

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

Better organization of boarding procedures. Terrible leadership guiding people to gates.

They need to improve on how the plane lands cause it was not smooth at all.

I did not like how the plane landed. It was not smooth.

China Airlines crews are very excellent doing their job. Very friendly and hardworking. I will always choose China Airlines over and over. Thank you all for making my flight comfortable. God bless to all the staff. :)

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.

Not great, will likely try to fly another or maybe I should have upgraded my ticket? Needed Air…

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

Love flying Asiana. Been using it for over a decade now.

Coming back to America was a peaceful flight everyone and everything was perfect

I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.

The staff was courteous and the flight was very smooth. It was so nice to see the captain greeting the passengers at the end of the flights.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

Flight was too cold. I wore a regular cotton tee and it wasn’t enough. It was a night time flight so I would have thought a blanket would be provided to passengers. A 4 hour flight and no options for a meal? I flew Asiana the next day from Seoul to Manilla. Same duration, 4 hours. They give everyone a pillow and blanket and serve a meal. Why is United so cheap and holding back meals and amenities? Also, they promote too much gay stuff and DEI in their advertisements. Please be mindful of other beliefs and don’t shove your gay ideology down my throat.

Staff always with a smile and very helpful with my mom who has mobility issues.

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

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.

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

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

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

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

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.

The staff on Singapore Airlines was incredible. I would like to commend LS Reuben from my SQ37 flight on November 19th, 2024, from LAX to Singapore, for his outstanding service and care. During the flight, one of my earbuds—brand new and valued at nearly $300—fell out and became lodged in the box controlling the in-flight entertainment system. I was understandably upset, but Reuben went above and beyond to assist me in this tough situation. Reuben demonstrated exceptional determination and empathy. Instead of suggesting we wait for an engineer, he immediately took action, spending almost 30 minutes searching for the earbud. He even got down on the floor to ensure it was recovered. His genuine concern and persistence made all the difference and turned a frustrating situation into one where I felt truly valued as a passenger. Reuben is a shining example of the remarkable service that sets Singapore Airlines apart. His dedication and willingness to go the extra mile left a lasting impression, and I want to sincerely thank him for his kindness and professionalism.

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

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.

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