The flight crews were extremely professional helpful and courteous. Departure and arrival times were accurate. No delay. Thanks

Not very comfortable seated in the back plane due to turbulence

Everything about Korean air is great, hands down! Will always prefer this airline from other carriers.

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

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.

New plane. Perfect gluten free meal Very flawless procedures from check-in to the landing. Taking off on time and landing even earlier and the luggages are already there after shortest arrival report.

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. :-(

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Stewardess are nice. Food could have been better and should have a better dessert. They do not offer scotch or beer. You have to ask for it. I also was not happy that you do not serve ginger ale and or cranberry juice. This is my first time that an international flight do not have this. I go home overseas every year and when I travel through ANA, Delta, Qatar, JAL, Asiana Air, United Air. they all serve this two very famous drink. You do not have a great snack tray.

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

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.

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

Ground and flight crew were all courteous, extremely helpful and professional. Overall, process is really organized, from boarding to disembarkation.

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

Food was high quality. Crew was extremely professional, polite, attentive. Flights were on time. Plane had good media tech.

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 .

Lovely airport at Haneda. Great food selection. Spacious and private boarding area with dedicated bathroom for each gate.

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.

Asian Vegitarian food was test less No Salt or pepper served Need to improve with Chef who can caters for Peaple from India I am sure Chef knows different varieties of food Indian People like

The flight attendant, where kind of rude, there where hiding for almost 3 hours, without doing rounds to see if people needed water or pickup the water cups, the toilets were full of water cups, because they never come back to pick them up.

Amazing service and fabulous syaff. Loved the jumbo jet too, comfortable.

The entertainment screens are dated and needs to be changed to new screens. Then when we got home, I found out 2 of our luggage’s were damaged (huge) and some items stolen.

I could not choose my seat prior to check in

JetBlue's check-in was great, but there was an in-flight attendant who was very rude and unkind. I didn't realize that the bathrooms were already locked 30 mins prior to landing and needed to use the restroom. Instead of politely asking me to return, she rudely told me, 'NO, bathrooms are locked! Go back to your seat!' The JetBlue flight was more than an hour delay, which made me almost miss my connecting flight with Asiana. I understand the reasoning, but the action they took to get a hold of maintenance was time consuming. It took them more than 30 mins to get a hold of maintenance and for maintenance to get started. The Asiana flight and crew were wonderful, in general. They waited for us who were delayed from the previous flight before they took off and were very kind to take my checked baggage's info. Seats were a little uncomfortable for such long flight, but service and flight attendants were great! However, my 3 checked baggages are missing! They're lost somewhere in the transition. I'm writing this review 3 days after my arrival to the Philippines, and my 3 checked baggages, where my wedding dress is, are all still missing! I and the CEB airport crew have sent multiple emails to both JetBlue and Asiana, and neither has responded to any of our emails. Although, I was able to get in contact with JetBlue's Interline Department who confirmed that the bags were turned over to Asiana without confirmation details.

Airfare was ok . Food not good , seat ok but not comfortable. Lay over too long , crew was ok Overall just ok

The crew was amazing and really nice. The OS on the entertainment system could use an update, though. It felt old and outdated but had anything you'd need to keep busy. I usually never use it anyways, but that did stand out.

2 things that really tanked our experience with this trip with Asiana Airline (which used to be among my favorite airlines): 1) The "random" security screening at the boarding gate is crazily thorough (which is completely redundant to the security screening before we went through the security checkpoint before getting into the gate area), and the water was acquired inside of the gate area (from a lounge operated by the Inchon airport). We were asked to take out *EVERY* single items from the carry-on luggage and open up every comtainers / bags / packages to inspect. To add to it, there were two inspection workers there (one seemed to be a trainee and the other seemed to be a trainer), and the trainer worker held a very unfriendly / arrogant attitude towards us. As the youngest member (a minor) of my family was being "screened", the rest of my family wanted to make sure that no inappropriate actions would happen to her. That trainer worker yelled at us and attempted to use rude body language (waving her hands) and facial expression to ask us to stay away. 2) The luggage handling at the destination was really *REALLY* bad. Among my 25+ years of travel experiences, I'm going to have to say that this was the worst luggage experience where we didn't lose our luggage. Our flight was scheduled to land 12:45pm, and landed around 1pm. 15mins delay in landing is absolutely normal. Deplane process took a bit longer than usual flight (we waited for around 20mins, after arriving at the gate, before people were able to actually leave the plane). However, the luggage took another *2 HOURS* to arrive at the baggage claim carousel. This is insane. What's worse is, due to the delay in luggage, the flurry of passengers from our flight collided with 3 other incoming flights. The US border / custom line was like the longest Disneyland attraction line winding through the entire arrival hall and around all the baggage claim carousels (like at least a thousand people). I've never seen anything like that at SeaTec airport (US border control), period. The luggage claim experience really tanked our trust and overall impression for Asiana Airline's Seattle airport ground operational effectiveness and efficiency. This has to change in order for them to remain relevant / in-business with increased competitions from Korean Air and other Asia-based airlines.

The seats (legroom) are tight and chairs cushion is stiff (not comfortable). The crew was courteous, professional and friendly. There was no food / snack for this flight (very short flight, but still would be nice to provide some snack for the enjoyment).

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

I was sitting at comfort +. One of the Asian male crew was so loud when he delivered service. When he asked questions or what food you need, he was shouting. He must be a prison guard before going Delta.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Space and comfort was good. Staff could have been more helpful and friendly.

Crew was not friendly when I went to request a seat change.

Really impressive staff at airport and on plane, especially given how busy it was

Was a great smooth flight from Detroit to San Diego.

Meals were adequate but could be better. Lots of movies, podcasts, tv shows. We really enjoyed using our personal headsets highly recommended. 15 hrs flight great to travel at night.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Quit making seats narrower and narrower. The guy beside me spilled over in to my seat.

The service was non existent . Crew did very little didn’t even answer call button . Premium economy in this long haul was the worst I have ever experienced . Never again flying with them .

The crews are great.. Easy boarding. Inflight entertainment ok. Food is a disappointment.

The real big issue with this flight was that it was 3 hours delayed. Other than that, no big praises or complaints.

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

The seat is too hard and my back and bottom are having servers pain

All went fine. Boarding was efficient, staff was really friendly, and we were kept up to date on any changes to our itinerary. My only note for improvement is that on this particular plane, the recline in economy class was negligible. I know it's a coach seat, but I had another UA flight (SFO to BWI) and the seat was more comfortable with better recline.
