The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

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

Always fly with Korean Airlines. Best service great food. Nice and clean as always.

Staff and crew are wonderful, professional and courteous. Meal is delicious and snacks can be improved. Entertainment needs improvement, pls update selections of movies. I appreciate that our flight was on time

Flying with ANA is always a breeze. Seats are very comfortable.

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!!!🤢

It was very nice. I was a bit disappointed by the few meal services. There were probably more drink services that I missed while sleeping, but I would have liked the crew to bring more than one drink service before landing and to bring more than one drink service and coffee service after take off

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!

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

Ana is absolute world class They should not work with united

Japan and China airlines were incredible. On board service was impeccable. All the flight attendants were helpful, friendly, and always smiling. Airplanes were very clean. The boarding crew was extremely accommodating and very nice as well. Overall I was extremely impressed.

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.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

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

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.
