Very long flight time. Still better than a connection flight. Staff is very good at service. Vegetarian food is not very good.

Very long flight time. Still better than a connection flight. Staff is very good at service. Vegetarian food is not very good.

The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.

Lousy entertainment system. Crews are excellent. Meal is just mediocre.

Aircraft is pretty old. Seat is not comfortable. Meal quality is disappointing. Entertainment system is not impressive at all.

Great service and comfort level. You can have more of vegetarian food options.

It’s great, long flight and arrive safe at destination

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

I can't believe they put my wife and I in the two middle seats! It is a very long flight and we had single flyers on either side of us blocking the way to the bathroom! There's no reason to not give one of us the isle seat so we could have managed bathroom needs and snacks with convenience. So I think very poorly of Korean air to put us both in the middle, I've never had that happen before and will probably avoid this airline in the future because of this. We tried to have them change it but they didn't so you pretty much lost a customer because of it.

There could have been better spacing of the passengers, it was crowded in some parts of the plane then other while rows were empty

Plane took off on time and I had the whole row to myself!

Smooth sailing trip, pilots are good. Less amount of food offered but the quality is okey.

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

Kayak uses scammer sites to steal money from their victims.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

When one asks for water because they are dehydrated, bring more then a sip or two in a small cup. Bring them a whole bottle.

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

I am thankful that I was able to fly using Asiana

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!

Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

Everything could and should be better. We are paying for, it's not a favor, it's a service and should involve quality, responsibility and respect.

Seats were comfortable, 8 hours. One flight attendant was not appropriate in his verbal response: "Please, DON'T touch me.", after being tapped near his elbow after being made unaware he skipped serving me & had passed further down the aisle.

Boarding in Amsterdam is always chaotic. More complicated than needs to be ( boarding pass checked twice, once for general security, then by the airline). The bathrooms on this flight are dirty, and smelly. The food was mediocre at best The crew was decent

Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.

Round trip flight to Canada and back to the US was smooth and efficient.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

Spanish speaker flight attendants were incredibly rude. A male flight attendant named Allen, grabbed my bag out of the overhead bin and moved it without my permission. When I asked what he was doing, he informed me that the overhead bins were public space? It would be easy to ignore this comment, as you don’t know the whole story, but the flight attendants were militant and rude. Delta, you can do better!

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

Terrific in every way. On time, professional staff, multiple movie options to select, great food and drink.

My bags were misplaced!!! Im in a foreign country with no bags

I liked that it was on time, however, the food was not good.

Offered to check carry on to final destination. This is the most absurd thing in the world. I'm carrying on because I need what is in the carry-on. I'm okay with picking up at next stop but then I will be on much larger plane that can accommodate it. Also, if there is ever a change to your flight. Go to the airport and have the people there fix your ticket. Don't do it over the phone or online with United they screwed us up and ended up with flights for our last leg that took off before our first leg.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

It was okay, the food was good, but after the landing there was not enough time for luggage and security to catch a connection. It was crowded on board.

When I went to check in at the United counter in Barcelona, Spain I had 2 different menat 2 different times in United uniforms (standing around with a couple other employees) ask me if I was traveling alone. The one man asked me 3 different ways if I was traveling alone. I am, 68 yeaers old and have all my faculties. I thought it was weird and it made me feel very uncomfortable. What difference does it make if I was traveling alone or with someone? What if I was a recent widow? That would have been horrible. They never gave me a reason why they needed to know who I was traveling with. I was hesitant to question them because I needed to be on that flight.

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

Crew was great. 2 1/2 hour delay was due to staff needing "rest" was avoidable and self inflicted as United not willing to hire enough crew to keep flight on time.. Ridiculous. The crew and the passengers both suffered due to this.

Flight operated by PAL. We boarded, and one engine started. The crew found some problem that could not be fixed. The flight was canceled. This run from yhz-bos is very unreliable.

Everything. The crew was so friendly, helpful & smiled. We had an excellent flight getting in earlier.

Flight attendants were ok. But it was a full flight.

Flight itself was not bad at all. However: my checked bag (checked in Calgary) did not make it onto this flight as I found out after I landed at EWR. I still don't have it but it appears that it is on its way to me.

Flight and attendance were very good we had 2 hour delay that took the shine of it

After 3 hours of delays, they ended up cancelling my flight. And although I could purchase one-way tickets to get to my destination, they would not offer me these flights as compensation for the cancelled flight, and I didn't end up making it home until 13 hours after I was originally supposed to arrive. It made for an extremely strenuous end to an otherwise good trip.

Be careful about the bad policy and when purchasing seats

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

The flight was delayed, but not for weather. We landed over 3hrs later than planned.
