Reviews of the top 5 airlines serving from Thailand to Illinois
Picked our seats when we purchased this flight (2 seats alone on the right) but were assigned two middle seats in the middle row at the gate. Very disappointing for a 10 hour+ flight, and what is the point of picking and paying for seats ahead of time when they just reassign us?

First international flight where the meals were not to my taste.
Overall, my experience with EVA Air was mixed. The highlight was that the airline clearly tried to provide a premium dining experience by offering the Michelin-starred Kanpai Classic beef yakiniku rice. However, in the limited space of an economy-class cabin, this meal felt overly oily and not very practical to eat. The sauce and grease made it easy to get one’s hands or tray table dirty, and after the meal many passengers may need to go to the lavatory simply to wash their hands. While the food itself may be high quality, the presentation and practicality did not seem well suited to an in-flight environment. Another disappointing part was the paid Wi-Fi service. I paid for the internet package, but the service did not work properly. What made the experience more frustrating was that passengers then had to spend additional time requesting a refund, and the refund process itself was slow and inconvenient. For an international airline, I think a malfunctioning paid service should be handled more efficiently. As for the seat, I feel EVA Air’s economy-class seats may be more comfortable for Asian passengers or people with smaller body frames, but they may not be as comfortable for taller or larger Western passengers on long-haul flights. The overall cabin environment also varied during the flight. Some passengers were not very mindful of noise, cleanliness, or shared cabin etiquette, which affected the comfort of the journey. I believe clearer reminders from the airline regarding cabin manners and hygiene could help improve the overall passenger experience. In short, EVA Air has some strong points, especially in trying to offer a premium Taiwanese-style service, but there are also areas that need improvement: more practical in-flight meals, a more reliable paid Wi-Fi system, faster refund handling, and better cabin management during long-haul flights.
Other than spotty internet, great servic, comfortable and smooth flight!
Crew was good. Sometimes food was eh. The spaghetti is gross for me. First time i got food, they didn’t provide utensils so i ate with my hands. I was hungry. They gave it to me 20 mins later when a crew member came by. I would fly with them again. Nobody is perfect
Eva airlines has very goin service, despite being low cost. Meals and fin, not amazing, restrooms always clean and staff polite and helpful
Pleasant crew. Very long flight, a bit uncomfortable at times being seated, but not too bad.
No ice for the drinks. Only gave a half a cup of your beverage. Not enough water. I got very dehydrated.
Polite hard working crew. No complaints really. Meals were not to my liking.
Everything was fantastic! The crew really went above and beyond to make it a great flight. I felt cared for with EVA.
I always enjoy flying with Japanese Airlines. The whole experience is always a pleasure. This flight was no exception. Thank you Kayak for making it so easy to decide.
Overall, it was ok. The attendants are nice. It was a short flight, and I did not use the restrooms. What I was frustrated was the check-in. I was to fly from ATL to Chicago (American) then change to Japan Airline to go to Japan. I checked in, but I only got a boarding pass for the flight from Atlanta to Chicago. It said I would need to check in for a flight to Japan on Japan Airline site. When I tried to check in on JAL website, it said I need to check in American... It was very confusing.
service was excellent. crew very polite, courteous, and good service especially to passengers like me who is a wheelchair passenger
The flights were on time and the cabin crew were very nice. The only downside was that the food was not good
Very comfortab flight. The flight crew and service was terrific. The food was average at best.
Excellent service, excellent food and beverage options, plenty of legroom
Check in procedure is harder than with other airlines, infotainment system is outdated
great experience - staff were kind and attentive and food was excellent. very comfortable flight that felt much shorter than 14 hours.
JAL is an exceptional airline that shows the true heart of Japanese omotenashi service. If the option is available I’ll always chose it
I would like to add American food so tired of rice after being there for 10 days didn’t want anymore to pay an airline did not have my bag marked right so it is still sitting in O’Hare. I am home.
"The Room" is the only way to fly. The service was excellent and the stewardesses we all gorgeous and friendly. The boarding process was delayed and the attendants at the airport were not the best.
The flights with ANA were great. The flights with United, not so much.
Attendants were very kind and frequently offered water and snacks. Food was excellent. For some reason, my IFE system would not play dialogue for any media despite my efforts to change to different language voiceovers, restart the system, etc. so I could not watch any videos.
Staff at gate and crew on plane efficient and friendly.
As always, there is that one or two flight attendants that could be better.
It was good. The crew was efficient, food was good
Vegetarian options were not that great. However, the crew and service was awesome
Entertainment was good , comfort on airplane easy hoarding food and drinks was good and a friendly and good service of flight staff
I was good seat to keep stretch my legs . but couldn’t keep my bag in my hand . because they told me can’t keep my seat is no holder , because no seat fronts of us. wish I can put my leg on something higher. but instead of that everything goood.
Good airlines btu ORL airport messed up the return flight for me. Checking out a connecting flight pax is unacceptable.
Excellent service in business class. Well worth the slightly higher fare as it includes lounge access, additional luggage weight and a full hot meal on board.
HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q
We still get drinks and a snack. Love the gift bags too.
business class is old but still done very well by the team.
Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.
Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience
Need to improve on punctuality. My flight was delayed by 1 hour.
Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.
The flight was mostly fine, but I really wished that seats had an outlet to charge devices considering the length of the flight (15 hours there and 14 hours back).
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.
Quinoa chocolate cookies are my favorite! Would be nice to have internet service like American
Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!
Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.
Legroom in Economy was fair to good. Seat was omay; I was hit in the shoulder twice by the cart as it was being whisked through the aisle. Overhead space was good for my carryon. Lighting environment was nice
We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.
Raleigh to Chicago was OK. The problem was Chicago to Lincoln. Flight was delayed 4 hours. Give them credit for the updates and reason why it was delayed
Comfortable seats and good crew. There should be some breakfast options in menu for economy class to purchase Wifi was not working in the flight
On time. Accommodated carry on and personal bag in the plane. Good entertainment available and access without using own device. Gave a whole can of juice rather than a pour. Seat did not recline much.
Good, our flight was delayed but that was totally out of their control due to weather and a presidential visit.
The price. Omg $1100. Was crazy and it was not clear on the website.
