Cons: "Have no recommendations...everything was great"

Pros: "The crew was fantastic"
Cons: "I was very uncomfortable in my seat. I purchased a seat with more leg room but didn’t know that exit seats don’t have the same width as other seats so my hips were in the seat tight. I wish I would’ve known this before I bought the extra legroom."

Pros: "Crew was very friendly and plane was on time. Food was good and also had various snacks in between meals. One of the things I liked most was that they had nitenacks in the restroom."

Pros: "Crew was awesome! Very attentive and friendly. Food was better than expected. Seating (premium economy) was very comfortable."

Pros: "I paid an extra $150 and the seat was tiny, yes had extra leg room, but regret paying the extra $."
Cons: "They made me move 1lb into my main checked bag from my carry on. The weight for carry ons is hardly anything and they didn’t check the weight of my friends."

Pros: "Comfy seats (no need for pillow), large touch screen, generally clean"
Cons: "Better food. I love airplane meals and been on many different airlines and sad to say, eva air has the worst food out of all of them"

Pros: "The price. The staff was professional and friendly."
Cons: "Everything was good."

Pros: "Free food!"
Cons: "N/A"

Pros: "The crew was very good at serving the meal. The crew did a great job telling passengers to get back in their seats when they were standing up while we were on the run way after landing."

Pros: "Crew was great and food was good toom"
Cons: "Might be out of your control but the turbulence got pretty rough at times and was alot more than any of my flights I've been on."

Pros: "I had a medical emergency and the crew took very good care of me."

Cons: "The flight was great"

Pros: "Everyghing"

Pros: "Very accomodating crew. One of the nicer airlines I’ve flown on. Newer, well maintained clean aircraft."

Pros: "EVA Air is an excellent overall airline."

Pros: "Being able to check bags and get boarding pass at Taipei Main station prior to boarding MRT (similar to Hong Kong) is a very useful convenience. EVA staff there were extremely pleasant and helpful."

Pros: "EVA Air has just got it figured out, solid from boarding to departure"
Cons: "Faster airplanes, or I could pick shorter trips"

Pros: "Very comfortable flight, many amenities included. Meals were excellent. Hospitality was exceptionable."

Pros: "The plane wasn't full and we could spread out. Food was fine."

Pros: "Flight left on time , flight attendants made the flight great"

Pros: "Taiwanese food Boarding orderly"

Pros: "Was a way home. Bathroom clean"
Cons: "Food was terrible. I’ve flown with Eva many times but the food is worse than ever. If your Chinese you can put seat back in meal service but if not Chinese must obey rules. The entertainment has very little to offer for such a long flight. So board. The seat is very uncomfortable and deflated seat is painful to my back. Flight overbooked in economy and many seats available elsewhere, they should offer for a little more money but leave empty while everyone is crammed like sardines"

Pros: "I like the whole round trip flight. from smooth and fast boarding process to big leg room for my premium economy seat. Food are good with 2 choises and staff are pleasant."
Cons: "Nothing I don’t like"

Pros: "Feeling much better than others"

Pros: "plenty of movies to watch."
Cons: "the second meal options were not to my liking. I chose Pasta, but i did NOT like the pasta meal: Too much pasta, not enough chicken."

Pros: "My roundtrip flight from Chicago to Bangkok was excellent for many reasons. First, my flight from Cleveland was delayed, and the EVA crew was quick to communicate with me and be sure to get me to the gate so I didn't miss the flight. The staff were all very kind, helpful, competent, professional. The airplane was very clean, very efficient, good meals, good entertainment. Excellent airline. I'll be flying with them regularly!"

Pros: "Great crew, impressive washrooms, food was wholesome and warm"
Cons: "My friend had a long wait in line to get her boarding pass. She was denied at the counter to fly due to there being 40 minutes until her board time. She was not checking bags, and the security line was a walk through. But they would not issue her a ticket, cancelled her international flight, AND her return flight. She had to buy an entire new round trip international flight...All the while her plane was still on the ground...This did not make sense to me. This does not make sense to anyone I explain the story to, either. Your counters truly are always long waits. It was her fault she didn't leave enough time. But the lack of flexibility in rebooking and the inability to still use her return flight home? WHY."

Pros: "Everything about my flights.."
Cons: "None.. they were very acoomodating of my request esp my seats"

Pros: "I liked that the Airline was very accommodating in arranging an alternate flight for me, after they caused me to miss my Connecting flight in Taipei, due to the delay in Hong Kong. I didn't mind being redirected through Seattle first, and then on to Chicago, but. . . . ."
Cons: "The 1hr, 40 minute delay in Hong Kong ended up costing me 11 hours of additional travel time to reach my final destination. The Airline arranged for the last leg of my flight to Chicago from Seattle to be on a different Airline, and it wasn't so comfortable. Arrangements were made by the airline in Taipei for my flight out of Chicago for me also, but with a 4 hours layover and on a "Standby" condition. This I didn't understand because there was a much earlier flight leaving Chicago on this same airline and it wasn't full. Staff at the ticket counter did eventually correct it to the earlier flight for me."

Pros: "I Like the AirPlane d staff but not d food.There food should needs improvements it looks ordinary."
Cons: "Absolutely their “FooD” a lot of riders or my friends & family complains their food."

Pros: "Seat is comfortable, washroom very clean"
Cons: "So far none since this is my second time in Evaa Air."

Pros: "First time riding this airline on my trip to Thailand and back. My friend always raved about it and now I see why. They do above and beyond for every customer. The flight attendants are prompt, kind and very hard working. Wish I could fly with EVA air more often."

Cons: "We love there service no complaints"

Pros: "First time flying , smooth journey, nice in plane entertainment, food, crew etc"
Cons: "TAIWAN airport has free half day tours."

Pros: "Thick blanket, toothbrush & toothpaste, eyes cover for sleeping, on time boarding, excellent overall"

Pros: "Staff was efficient and pleasant. The food was excellent and nicely served."

Pros: "Lounge in Abu Dhabi was great!"

Pros: "Newer aircraft. Fantastic service"

Pros: "Departed on time. Seat was ok."
Cons: "Check-in and boarding was too long and confusing. Too much to walk between one place to next. Overkill on security and baggage check. Food was terrible. Second full meal was chopped up to just a salad and main dish...no bread or dessert. Air hostess could be more pleasant. Flight was late 1 hr."

Pros: "Well, it got me from Point A to Point B I guess"
Cons: "You cannot book seats in advance which is fine but one would expect that if you have 3 seats on one reservation, you would at least be seated together - nope 3 window seats all over the plane. Boarding was delayed for no reason. Bags took (no exaggeration) about 1.5 hours to come. And it is a hot mess with no carts"

Cons: "The seats never recline. All the 4 leg seats had reclining ossue"

Pros: "Comfortable"

Cons: "Our Chicago to Abu Dhabi flight was delayed by over 6 hours Our Abu Dhabi layover was long, because the airline ended up canceling/delaying the connecting flight"

Pros: "I have always loved service of Etihad airways. The food was awesome. The staff was friendly and courteous. Seats were comfortable. Surely enjoyed every bit of it."

Cons: "I wasn't able to take the flight for the reasons mentioned above."

Cons: "The seats we had were very hard to recline. For the first 8 hrs of the flight w my sister and I could not get the seats to recline The flight attendants would pass us by without asking we wanted anything to drink. We felt totally ignored particularly dine we were seat in the center two seats in the middle section."

Cons: "Cramed. Bad food. NO CONTROL ON SIZE OF LUGGAGE ALLOWED IN CABIN"

Pros: "The service and comfort!"

Cons: "Food wasn't great."

Pros: "Everything"
Cons: "I couldn't sleep on the plane."

Pros: "Overall flight experience was good, but the ground staff need to be more real time responsive and should own responsibility."

Pros: "Professional staff, super helpful and accommodating, great with kids. Food is great if you like Mediterranean. Movies, TV, video games, music all free. Neck pillows for everyone on trans-Atlantic flights."
Cons: "New policy (thanks TSA) that prohibits laptops in the cabin. Have to check them and risk getting smashed."

Cons: "I had to wait more than an hour when I pushed the help light button, even though there was no troubles in the air! Also, I asked for a cup of water couple of times, well over 30 min, and I only got that cup with the meal!"

Pros: "Good nice flight feel like you sitting in bussiness class"

Pros: "Bad services over all"

Pros: "Services n hospitality"
Cons: "Washroom maintenance can be better."

Pros: "Fantastic crew! Good selection for tv, food was good. Baggage checked all the way through, no problems or complaints at all. Will definitely fly Etihad again."

Cons: "Hair was served in the food and the etihad airlines did not do anything other than offer a mere 10k goodwill miles and said even that they don't do but we're doing me a favor by doing so. I would never travel again on this airline ever."

Pros: "On time / shedule ahead departure or arrival."
Cons: "Seating arrangement."

Cons: "Food. Not served according to the menu. Kochi to Abu Dhabi -vegetarian. Abu Dhabi to Chicago __vegetarian no options. -Vegetarian food not tasty.At last before landing in Chicago some non veg."

Cons: "They took close to one hour to check us in and give us boarding pass. Once it was delayed, with no time to get things in time for security and boarding we had to rush with two kids. Although there was one checked bag allowed for infant according to the reservations they charged us 100$ for additional bag. Despite them delaying the Check in process they said if I don't pay for the checked bag I will miss my flight. This is becoming more and more of a problem with American Airlines and looks like Etihad cares less for this and they simply told me in Chicago that it was American Airlines issue and not theirs! This is totally frustrating and I will avoid American Airlines connections And future flights with Etihad as well. International travelers watch out for connections with American Airlines."

Cons: "Wheelchair facility should be prompt. we had to wait for an hour to get it.. Also it is not that spacious.."

Cons: ".."

Pros: "Ground staff was good"
Cons: "Flight delayed"

Pros: "Crew was very helpful and entertainment options were good."
Cons: "Food can be better and limited access to WiFi (free) would be great. It was too expensive per flight."

Pros: "Everything else."
Cons: "In other wise excellent service, carry on bag size policy is not practical, Please keep it similar to other airlines. Please don't expect us to get a separate bag size to fly on Etihad. This one headache which could remove Etihad from our future travel consideration."

Cons: "The nine hour delay. The lack of information and run around during the nine hour delay. The lack of information and run around once we landed and got our bags, were rebooked on new flights, were given hotel/food vouchers."

Cons: "Food"
