Korean air has a little bit more seating space than Asiana air.

This flight was a superior flight in all regards. Extremely pleasant experience.

Unfortunately, there has been a boarding and departure delay. However, as usual, the flight arrived earlier than the scheduled. There has been a turbulence in-between, it’s unavoidable. I couldn’t complain them.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

They were very accommodating of a dietary issue. Nice movie & tv selections. Non-stop helped get through a very long (15 hr) flight

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

The boarding process for Korean airlines is very straightforward and easy. You've never met such helpful and friendly people. The food was great and the entertainment options were excellent too. My teenage boys found programs they wanted to watch while I had fun watching a full season of the Last Man - the Blind Investigator (Japanese), which my wife enjoyed too. My only complaint was that it takes a very long time to taxi at ICN (20 minutes) and the pilot had to hold at the gate for 10 minutes after our scheduled departure time, which meant we got to Seattle 27 minutes late. Luckily I had a long enough connection to make my next flight, but just barely.

The food on this flight from NRT to ICN was average. The staff were very friendly, but the flight took about 60 minutes longer than it should have because the pilot was only flying at 330mph instead of 500-550. Not sure what the reason is for that, but it meant for a much longer flight.

Love flying Asiana. Been using it for over a decade now.

Coming back to America was a peaceful flight everyone and everything was perfect

The staff was courteous and the flight was very smooth. It was so nice to see the captain greeting the passengers at the end of the flights.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

Staff always with a smile and very helpful with my mom who has mobility issues.

It was amazing. I was not expecting the phenomenal customer service Asiana provides.

It was all perfect and very pleasant for such long flights

The seats felt very small. We were supplied with pillows and blankets, which was nice. Lots of noise from the bathroom, plus exterior noise. Made it hard to hear the entertainment system, even using my own noise-cancelling headphones. The food was really bad. I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Two meals were served on this flight; one was a repeat of the meal I had had on the flight immediately preceding this one, which was bad enough I didn't even try it. Drinks were very limited. All I wanted was water, and on a 10.5 hour flight, I was given 3 cups of about 3 ounces each.

We took business class, It was comfortable and I was able to sleep.

2 hours delay, time changes started already 2 days before the flight

Average, not more then that. Cannot compete with Singapore Airlines

I bought the front row seat and made and early online check in but they changed my seat to the back row without prior notice. The inflight meal was too poor, only a piece of small finger food. The boarding is a disaster, everyone is stuffed in a bus in chaos. Doesnt worth the money at all.

Poor. Flight was delay without prior notice. Poor boarding. Poor meal service. Plane was dirty and smelly. Does not worth the money.

Overall very nice airline. The seats were cloth unlike leather seats I am accustom to on planes. The food was adequate. I had to use a paper boarding pass as they do not like electronic boarding passes. I scanned my electronic pass, but the gate agent requested the paper pass. Luckily I had a paper pass, although my electronic pass worked and when the paper pass was scanned it stated I was already on board.

I am a bit upset with the check in counter, I signed up a wheelchair for my mom so they wouldn’t grant us her boarding pass. We got to the airport a couple of hours earlier and they had us wait and no one ever gave us her boarding pass or the wheelchair, I had to go back and complain when it was already time for our flight to board. Since we got their earlier, I could have easily pushed my mom myself and we could have relaxed and went to the lounge while waiting… when I finally got someone to help us he couldn’t explain how and why they dismissed us in the first place.

Was on holiday with my partner and we booked with Vietnam airlines as it not meant to be a budget airline. They separated us and made us sit at either end of the plane. Not the way I planned to spend my time on my holiday separate from my loved one. How can they separate people on the same booking. They know we are together and spending quality time together.

I had sometimes my trips with Vietnam Airlines and I like it 😊

The check-in process was great, and I cannot remember the name of the supervisor, but he was good and told us about the transit process very correctly and efficiently and kindly. We were given down access and the overall process was very efficient.

At the boarding gate, Jeju airline accepted "carry on" bags for checking in for free due to the "limited cabin space". This is because most passengers were carrying multiple bags that exceed the size and weight limit for carry on items. Rather than inspecting carry-on bags at the counter and requiring excess bags to be checked in for a fee, they allowed freeloading at the boarding gate to to the detriment of those who paid the fee for checked bags. This is totally unfair.

As posred earlier the crew was very accommodating & professional. Thank You Allen

All though you can not help it the kids was loud and unruly, The crew was very accommodating and professional. Thank You Allen.

No priority counter check in for families with young children.

The flight was delayed from GUM to ICN, there was no notification on how delayed the flight would be. Although we received notice, there was no specified time given. The flight was also very uncomfortable.

Cons: "Sold me a ticket then cancelled 15 minutes later due to not having updated information from the airline on bookings."

The flight was OK, but you need to warn passengers going to Vietnam that the full first, middle and last name needs to be in the issued visa, At least 5 passengers on that pane did not have that. We all had to pay $298 each to some agent to amend the visa. At least one lady could not and was left behind.

VietJet is a discount airline like EasyJet, Flair or Spirit. I flew 3 flights in 2 weeks and all were Airbus 321's. 2 of the flights left and arrived on time and 1 left and arrived about 45minutes late. Seat pitch in economy is 29" but exit row seats have super-generous leg room. There are no power ports or entertainment of any kind. Food is best purchased on-line before the flight but there is a limited selection available in flight - cash only. The aircraft are clean and the airline is run as well as any other airline that specializes in economy passengers.

Our flight was 3 hours delayed and the airport was hectic as our boarding pass said one gate while the digital screens said another gate. Attendants were clueless and said to watch both! Vietjwt cared more about selling their merch than even providing any water for the 2 hour flight

Cheap flight but more expensive when the airlines demands you pay over 30$ for 1 kilogram overweight ( it is 8,2kg I have for carry on baggage) The flights announcement 2PM, and it departed 4 PM, no announcement for delaying, People says Vietjet is delayJet airlines in their blood.

Vietjet tried to steal extra money from passengers by forcing them to change the name on the ticket that was correctly filled in on an English form online when ticket bought online. I bought the ticket via a foreign website where the language is English, At filling in the passenger's name, it says middle name first, then first name, and last name, That the ticket done and printed. when my wife checked in the staff at the check in counter said that her name was written wrong, she must fill the name in Vietnamese style, writing the Last name first, then middle name, first name comes last, even though her name was not misspelled. At the aiport I asked the Vietjet customer service, if it is written in Vietnamese way, it will be wrong when she travel abroad ? The custom service could not answer. It took over an hour where my wife was thrown like a ball between the check-in counter, to the Vietjet customer service , then to passport control. The cost is 110,000 vnd for change place in vietnamese way, I thought if there are millions of passengers who have done the same mistake, how much money Vietjet raked in every year On the flight, it is not allowed to sit in the empty seats in front or next to me, I sat in the middle in a row where two big men were sitting, I really need to change seats but the crew asked to pay extra to buy the empty seats. It is petty and cruel of Vietjet. There is no other choice than the state-owned airline, then you have no choice but to swallow the bite

Our flight was delayed for about 3hours however the ground crew made it sure that we will not miss our connecting flight from Hanoi to incheon.

If there could be simple free food or snack or some entertainment.

Seat pitch is narrow moreover the agent assigned seat in front of emergency exit window which is not reclined. A terrible 4hr 40min flight from HAN to DPS

Horrible! As an Asian, they look down on their own skin color. Disgusting people and airlines. If you are white, they will worship you

1-Airlines did not send any info to inform the clients about changing fight number. 2-Delayed too long on runay without any explanation
