I put the review all together for the first review

I liked that they gave us a couple of meals and drinks but the meal was not good and not many options especially if we are seated in the back of the plane.

Again on this leg the WiFi wouldn't work. The seats were comfortable with adequate cushion and space between seats for my legs. Very nice 3-hour flight.

Very nice, I feel I got good value for the price.

Certain flight crew member were rude and short with me when I asked questions.

Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

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.

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.

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

Eva air is a good airline. The seats on the way to Taipei could have certainly been more comfortable, but all in all it was a pretty good experience.

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

Lousy entertainment system. Crews are excellent. Meal is just mediocre.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

Unlimited drinks and snacks on this long flight. Very courteous Korean staff !!!

It was a great experience in all aspects including passengers are respectful to each other. I will consider to fly with Korean Air again in the future.

Excellent service, love the extra amenities (water bottles, blankets, etc.).

They had the same movie choice as my previous flight, not much of a choice, movies were not up to date, music was uninteresting. Other than sitting on the ground for 40 minutes after boarding the plane, with pilot telling us that they couldn't load the plane because of rain, (bullshit) We finally got into Bangkok of course 40 minutes late.

Great crew, decent food Charging plugs were broken on both seats next to me. Only the USB port was available, and that charges, very, very slowly. Seat was also broken, it would not lock into position when reclining.

After the gauntlet of unnecessary security, and the two mile jog to make the flight, the flight was delayed 20 minutes on the ground for takeoff.. However, once in the air, the crew gave its usual excellent service.

Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.

Cabin Crew was excellent. They took care of everything requested. Flight was good

The ROOM was great. We would love to have it on all of our flights. LOL

The pilot was kept warning about the weather terrifying us. The flight attendants were not warm or pleasant.

Flight was good and comfortable, even for long haul economy. No complaints.

Almost 6 hours of delay with over 12 gate changes. Flight was supposed to depart around 6 and instead depart after 12am. No accommodations were offered than some snacks closer to midnight when the crew was planning to throw away some snacks.

Everything was good may improve some alcohol drinks and amenities during fly

Wonderfully pleasant experience. Good meal and beverage selections. Professional air staff.

Wonderful. I love ANA airlines. It's the best so far. My first pick when I travel now.

Loved that leg room was great for economy, and food was definitely better than other American airlines, great selection of movies. My mom is happy.

The service was better on this flight from the long haul one, but still very poor from The Cathay Pacific of the past.

Seat was very old. Didn’t easily go up and down. Flight Attendent had issues moving the seat. Condition of the seat was ok. Parts were peeling off by the foot area. Food was ok. Ran out of the dish I wanted so got the beef. Beef filet was very tender but the sauce was a little strange. Disembarking was very easy.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

My connecting flight was canceled or never existed. My stopover went from 1 hour and a half to 10 hours. It was a long day that I wasn't prepared for and it would have been nice to know that ahead of time. Cathay is great though. Great staff, entertainment and food.

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

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

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.

From Chicago to Hong Kong was great., but from Hong Kong to manila we had hard time looking for the gate of our connecting flight. There wasn’t hardly any sign.

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years
