The food is always good and that flight was particularly good.

Unlimited drinks and snacks on this long flight. Very courteous Korean staff !!!

Absolutely wonderful,love the big clean plane specially the good food.

Was an easy and great flight. On time. Food was tasty and the only complaint I have is something no one could do anything about. Seems like there’s a lot of ill people in Korea these days and the flight was full of people coughing.

I’ve always been impressed by the cleanliness of the toilets or, at least, its frequent monitoring, cleaning, and toiletry replacements. The in-flight service by flight attendants is superb.

Glad you had Bibimbap which tasted much better than mesh potato or pasta.

Absolutely horrible. The fight member crew or not very friendly and the food was horrible.

It would be better if flight crew can clearly communicate in english. But they are kind and accommodating. Food is good, especially the sandwiches on the self-serving snack trays. They are better than the ones served. Boarding was organized.

They could have had more up to date movies/better choice of music.

Terrible experience will never fly Delta again. Delayed flight with total disorganization and inept crew who wouldn’t communicate.

Everything was perfect. A flight attendant even brought me snacks after I declined food due to my desire to force myself to follow the destination time zone.

For the most part, it was an enjoyable experience. It's the 2nd half of the journey was a bit uncomfortable. It was on a noticable smaller plane compared to the previous one.

Only process that my luggage didn’t make it to my destination because of short connection but I understand

The boarding process was good. The toilet could be better maintained.

This has been the worst experience I've ever had. We arrived to Ho Chi Minh Airport and were supposed to get our Asiana ticket from the transfer counter as we came with a different airline. However, the staff at the transfer counter were not helpful and kept giving us different information. We were first told by Asiana airlines staff we had to wait 2 hours so they could print out and give us our tickets, then someone else told us we had to wait 3hrs, someone told us "I don't know, just go sit and wait and we will tell you later." This was at a place in the Ho Chi Minh airport that had no coffee or food shops, nothing, just immigration (to enter Vietnam with a Vietnam Visa) and security (to transfer into the gates) but we needed our printed boarding pass to go through. It wasn't until we demanded to speak to a supervisor as our flight time was 1hr away because they kept telling us "there's alot of time left for your international flight, we will get your tickets later" we still had to wait around 20minutes for the "Supervisor" to give us our tickets. I would NOT recommend Asiana Airlines, especially if going thru Ho Chi Minh Airport as they are not helpful. (We almost missed our flight, due to their lazyness and incompetence of printing our tickets) I would suggest Asiana Airlines to have a Machine in the transfer area so passengers can easily print out their boarding passes themselves and save some money by not hiring incompetent staff that can't do a simple task such as printing a boarding pass.

I like the food, the crew and everything.!!! Except for the delay in our flight.

Great service and comfortable seats. The first meal was excellent but the second meal was only satisfactory

The staffs are very accomodating!!! The foods are good!!! The entertainment from manila to incheon was miserable because we need to use our own cellphones or own ipads.

Typical Asian airline - flight attendants like robots - start food orders at first row and get to the last row right aisle last - no food selections left. 30 minutes before landing demanding everyone put seats back into upright position, window shades open and God forbid you might have to use the restroom a full 30 minutes left into a 1 hour 45 minute flight. At least the flight was cheap - but that’s the best I can say about it.

Check in agent very rude, no greeting “Hi” or “ Thank you. Doesn’t direct where to go for gate info. In flight crew staff not friendly. Very disappointed ☹️

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

Not good - chair back could not move back for premium economy. Not worth the price

The back of the chair - premium economy could not move back - not worth the price

It was okay. Boarding the staff made you feel rushed like we were late or something

It was great. The staff were so nice and helpful the food was great and they always made sure I was okay. As a foreigner I was worried about the language barrier but it was absolutely no issues. I highly recommend

Crew: Everybody was polite. People just need to get efficient and less reworking things. Entertainment: Could have move movies and games. The “music” section is a joke, only ONE available. Food: The food provided on the flights boarding in china needs a serious reworking. Too much oil, bad for your stomach, tastes too artificial and the eggs were a giant mass of green dough.

We were diverted to Chengdu, because of bad weather and finally made it to Chong King about 7 hours later

No wheelchair service at all ( I did request that service and also purchased the priority assistant bundle) , what a waste of money

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

I barely made the flight. We had to take a bus to the plane and the plane smelled awfully of body odor. When the flight attendant walked by she smelled of body odor. It was incredibly uncomfortable. Also my luggage did not make it onto this flight and when it finally arrived home the handle of the luggage was all ripped. I will have to purchase a bag again.

The flight was delayed but I was still able to board the connecting flight in Munich.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).

Prompt, efficient boarding. Clean aircraft and knowledgeable crew. Everything on time.

Seats were very small and of poor quality. Service was good.

Leg room was ok 1 flight attendant threw headphones at us. Very rude Overbooked flight thank goodness I got a seat Bathrooms smelled and urine all over the floor

Flight was late and I missed my connecting flight to Dublin. This is not the same Lufthansa I remember, you guys don't care anymore. Hopefully my trips with Swiss Air will much better.
