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 💜

It was ok. Not good and not a bad experience

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.

The crew was so accommodating. If I asked for extra snack they gave it to me. In economy the seats were wide and plenty of legroom. The backrest should have reclined a little more. Instead it barely moved. The footrest was helpful. Overall, my experience was good and I would recommend ANA as an alternative to other oversees low-cost airlines.

Older 777 - showing lots of wear - Premium econo seats that are difficult to recline and worn springs to they don't return to takeoff position without standing and pulling them forward

Excellent. All the ticket prices have gone up so much. With only economy as the option, I thought I better pay for a good airline and I am glad I took ANA. The only thing is the long layover at Hanaeda enroute to Singapore. Any chance to bring back the service to land at Narita instead for the transit and a shorter layover will be fantastic. I am a fan of ANA.

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.

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

I flew economy class so of course it’s not as roomy as business and first class. But overall it was ok and the seat had an interesting way to recline — the seat itself extended forward instead of the backrest. This way the person sitting behind me would not lose space by my reclining—excellent concept. I wish all airlines used these seats.

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

The staff, ground and air, at ANA was very helpful and friendly during check in, boarding and during the flight. This is the reason why I always fly ANA whenever I go to Manila. The food was not the best but the flight crew more than makes up for the shortfall.

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

The crew was very helpful. Food was prepared with great care and tasted wonderful. Movie selection was a bit limited. The bedding on the seat is a little too thin for sleeping.

Their announcement was not quite clear in Chinese. The rest is pretty good.

The hygiene of the bathrooms were terrible. Urine smells leaked out into the cabin and the seats were really tight, even for a petite woman like myself. Flight attendants did not go through the cabin enough to offer refreshments.

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.

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Overnight flight in the old style Business class, but still very good.

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
