Ford not that great the seat not to big for leg room like other airline

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.

Korean Air had great service and the Bibimbap dish was the best airplane food I’ve ever had. It was a long flight so in between the two meals they served customers could get Shin ramen. The flight attendants let my children use a pair of nice headphones for the flight and had earbuds and slippers for all the adults. The flight was long but the time passed by relatively quickly because they have many great shows in their entertainment TV. I watched the BTS Love Yourself and Speak Yourself concerts 💜

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

You did not put me on a Korean Air flight! so I do not have nothing to say

My flight was diverted to Atlanta and I was not given enough time. I paid my travel on April 23, 2023. It was originally Delta from Norfolk to NY, then Korean Air from NY all the way Philippines which is my final stop. Instead from Atlanta to Korea I flew Delta which is okay. Then Korea to Philippines, I flew Asiana Airlines. What I did not like, Ieagle did not sent me an email that my flight was change and so when I went to check in Wednesday the 10th, at 4:30 a.m they told me my flight was delayed at 6;00 p.m and diverted in Atlanta and I am flying Asiana from Korea to Philippines. I do not appreciate that Kayak or Ieagle chenge our flights 5 times and then last minute change again during my day of flight. I hope that you will not make any changes of my flight o Feb 15th because it has to be the same flight with my husband. That is the reason why we made the arrangements early on.

Wonderful cabin crew!!!!! Food was poor, in flight entertainment was just ok. They need to serve more water on a 15 hour flight--we were dehydrated and kept asking for water.

Going through security a third time to get on the next flight was again utterly ridiculous and unnecessary. We were in a International secure area once again and as far as I'm concerned should not have been put through the gears for absolutely no reason. The United States can get all the information they need from the travel itinerary, there was no need to be forced out of a secure area to personally interview everyone on a connecting flight to find out their US immigration status.

Flight arrived early, fantastic, since it is short flight, no food being served

I booked a ANA flight, this was just a regular United flight — as always very bad, dirty, rude service, quite frankly really embarrassing to be flying with this after spending time in Japan.

For the price of a seat that is obviously crammed together so as to get many more people onboard and combined with the long flight duration, Free WiFi should be an automatic “Thank You for Flying with Us!” To charge an additional fee when so many other businesses offers it is a bit “cheap” on the airline’s part.

First I will say this was really NOT an ANA flight. ANA used a UNITED jet to perform this flight. I specifically booked with ANA because I did NOT WANT TO FLY UNITED FOR INTERNATIONAL FLIGHTS. So to spend $1800.00 and then discover after booking that it was going to be handled by United was very disappointing. I will be more careful next time when I book. The interior was very cramped in economy class; the dinner meal was terrible and also had extremely small portions for an international flight - the bread roll was ice cold and stale - that salad was very wilted; I’ve never had a “snack” that was so salty that it was difficult to eat; the breakfast “waffle” was practically unrecognizable. Really horrible meals for a very expensive international flight. Bathroom floor was also pretty dirty. I’m hoping my return flight is a real ANA airplane that is cleaned and serviced by ANA personnel with ANA meals. I will never book with ANA again if they continue to use UNITED airline jets. Yuck!!!🤢

I wish the serve should leach and drink. Maybe because only 2hr

It was ok I thought because my flight was 1pm i was expecting to have lunch but it didn’t and after 7 hr finally dinner time was only chicken sandwich and next breakfast was an hour before plane land in Tokyo. so I should bring some food with me. Japanese flight attend was nice but the other was chewing gum and how she ask and respond to customers was not professional I felt. Maybe because Japan flight attendant is highly train and everyone looked very dress and professional so I was kind disappointed. I like that the bathroom was very clean .

Seat was roomy enough . The Asian selection for a meal was good . The tortellini was not very good. Service was excellent. O

It was very good. Lots of room with superior food and service. I will not hesitate to fly ANA in the future!

They did not get my request for veg food that i made a month ago. Also did not have any backup veg food on board or fruit plate or simething. Very disappointing as i had hward about how grwat ANA was supossed to be. Alsio entertainment was lacking and screen and tech was subpar. Overall just mid to low tie. They are living off reputation and are being passed up by most other carriers.

I love everything about this airline but it could be better if the waiting time for boarding is on time.

I chose my seat for the window: there wasn’t a window in my row. The charging function for my device didn’t work.

Fast and efficient boarding. Flight was on time. Service was very good for our long flight. First time flying with this airline and I would highly recommend.

Eva Air's Business Class is pretty decent. With the given price, I think that the food can be better.

Pleasant, comfortable, and entertaining. All told, ZERO issues with it. And sadly, so far the flight was WAY more comfortable than the hellhole that is "Lambug Beach Resort" at Badian Beach!

It was a pleasant fly with Eva Air from NYC to Taipei. The crew were friendly and the food was exceeded my expectation.

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.

Boarding is fast and easy for economy class, food was ok baggage policies are good

Overall the flight was what might be expected for a long haul flight to Asia in economy class. The cabin crew was attentive and the food was good. Boarding was fairly fast and easy. The one thing I found frustrating was the EVA app. It is terrible. Trying to do anything on it was almost impossible.

EVA would not help with ticket issue since they were purchased through a travel agency. Even though it was EVA ticket stock. Travel agency Budget Air didn't reissue ticket after airline change which I didn’t learn until trying to checkin on Christmas Day and there was no contact number for the agency to help. I will never use Budget Air to purchase flight again and disappointed in EVA’s refusal to help. Thankfully just under 12 hrs before departure someone from the agency was available to reissue tickets. I was starting to think we would not be flying and the stress trying to resolve was completely unacceptable.

seamless check in/ friendly staff, food is good, always love flying Eva Air

Very uncomfortable and crowded seats in economy. Flight attendant refused request to move to nearby unused seat with more legroom because “It was more money for that seat”. It was also near impossible to reach airline directly by phone. Waits upwards of an hour and not very helpful customer service representatives after long wait. Cannot recommend this airline.

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Atlanta boarding crew at gate were filled with arrogance and were disrespectful. In flight crew showed indifference to the needs of passengers. This is about the flight from ATL to BDL.

The plane was FREEZING SEATS UNCOMFORTABLE Otherwise smooth Thank you

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Boarding was somewhat chaotic. Unable to evaluate crew or food/drink because captain kept them seated due to turbulence. Have no idea if entertainment was offered.

West Jet has a horrible boarding process and the seats have no cushion.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

I was in business class, without the business class amenities. Large seat with lots of legroom, but no TV or bed. Food was okay, but I did enjoy the Turkish red wine.

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

The airplane from IAD to Istanbul was too old. The chairs were to tight and uncomfortable. I continued my travel from Istanbul to Bangkok. This airplane was better and newer than the first one. Even food was better.

On line check in needs a lot of improvement. I tried and gave up.

They use a smaller international plane and quarters are tighter, space smaller, and the flight is still 12 hours, then fight attendants are ruff, food is bad, cherry juice spilled by flight attendant and she comes back to ask why have we not changed yet could it be we didn’t have any clothes to change into and seat is all wet and we had to sit there for 12 hours

Food not good, flight attendants not the best, not accommodating very ruff
