Not very comfortable seated in the back plane due to turbulence

Crew was ok, but some passengers were a bit rude. Again, all outlets were not working, only the really slow charging usb plug on the entertainment system. Entertainment system was also bugged, some features just crash, the touch screen wasn't working and when trying to watch a movie the onscreen display kept flashing off and on making it very difficult to watch.

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. :-(

I flew Asiana Air not Korean Air which was my original flight. So, I have no say about Korean Airlines right now. I hope you guys will not make any changes of my flight on Feb 15th. I want to fly Korean Air on Feb 15th. and make sure it is the same flightr njumber for my husband also and do not make any changes on either flights. thank you for reading my letter.

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.

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.

We did not receive our special meal request (vegetarian). The crew was apologetic but then kept interrupting me at least 6 times to ask to see my email or access the web to show verification. (I did not have internet access while on the plane). They kept asking the same questions and taking down the same information. It became exasperating. I understand these errors occur but the constant questioning was disrupted and only compounded the error.

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.

Good. Got me there and back safely and mostly on time. 30 min delay for maintenance once but that means more time for nap. Crew was super nice.

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.

The space for the seats i like it. Its not too close like other air line. The food is ok and also the staff. I'm waiting for my flight rewards point because until now i didn't recieved it.

Flight was on time and the crew was as expected, friendly and respectful. Food could’ve been better though.

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!!!🤢

Ticket was purchased as a United Airlines flight (operated by All Nippon) like what does that even mean? Makes for a VERY confusing flight experience. For instance, what do I look for a United drop off signage and ticket counter or ANA? No explanation anywhere to be found. I also felt a little bit scammed by the obsurdely restrictive seat selection provided. Only middle seats available!! Are you kidding me!! On 6hr + 10hr flights you're forcing me into the middle seat without telling me before I purchased the ticket?? This should be illegal. And to top it off, on the Tokyo LA leg there were quite a few empty seats including window seats! I must also say, the food was a dissappointing as well for my taste, fish with rice ( mostly plain white rice) or a vegetable medly for the breakfast meal? Should be at least 4 choices and at least 1 with eggs. Outside of these issues flight was otherwise ok.

This is a very long flight and the first time I have flown on a Japanese airline. I was very impressed with the staff. They worked hard and offered food and drink regularly. Plane was very well cared for. The let room was good . Food was ok but better than other airlines.

Leg room and flight sound insulation is very bad. They broke 3 of my bags with bad handling

Crews were great but food not much selection just all tailored for Asian passengers.

I had a great experience with Singapore airlines as always. The partner airline, Scoot was fine except my bag was misplaced during the shuffle. Ultimately, my baggage arrived intact. Attempting to inquire about my baggage was impossible.

The Premium economy class is not the same as some other airlines because there are no economy seats on these planes. Basically you’re getting an economy seat that’s a little wider. The seats are not that much more comfortable. The service and food experience is similar to economy class on other Asian airlines. There aren’t enough toilets for the entire plane therefore we are forced to share the business class toilets that are closed off with curtains.

My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

It was a great flight Food was great Crew was spectacular

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

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.

The entertainment wasn’t playing in the app or online.

Lady was a bit rude during boarding and I was being nice to her.

Why does it have to be painful to fly long distances?

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Food is very bad and entertint not too many options ... flight attendet service is not good

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.
