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

Best service I’ve ever had Flight attendants are nicely dressed and look very professional

SQ is a market leader for good reason and its 787 this time was actually comfortable and the service top notch as always.

The friendliness of the attendants, and the quality of the service.

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available

Food was just okay, need to improve for other menu variations

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Food from Surabaya was below average but from Singapore is much better

My experience with Scoot is very good. Will have no issue flying with Scoot again.

I did not like anything. Flight experience was bad overall.

Please have the artiste showcase of classic international movies. Please have better food. There was no dessert or yogurt in my Ind Veg meal.

Very god service with smile. Aircraft a bit old, TV doesn’t work, luckily we can use our mobile to connect to their TV.

Very pleased. Very professional and organized. Very clean aircraft. Efficient boarding and even a snack.

Would not fly again. Everything is sub par. Honestly not worth the price we paid. Would have rather flown Jetstar and saved the money.

Friendly flight attendants, Did not care for the food. My headphones did not work because of a faulty jack at my seat.

Entertainment was poor at best. Very old movies and tv show and not really good ones .

It’s been a while and I saw lot of improvement. Flight was on time, friendly air crew, good food and comfy leg room.

For ground ticketing crew to honor the seat I’ve chosen instead of separating me from my family WITHOUT INFORMING me!

Good, ontime performance...hard products is somewhat out of date

I hopefully cancelled this flight and will get a refund. I am disappointed that you did not stop alerts about this flight and seem to think we went on it. It doesn't seem like your company communicates well internally. Also from my end, I hope you have some clout to resolve things. That has to be part of the package you offer. Thank You, William Ashley

At CGK, need to walk from one gate all the way to the other gate to board the plane. Which makes me wonder, why can’t we just gather at the correct gate in the first place?

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

Kayak uses scammer sites to steal money from their victims.

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 am thankful that I was able to fly using Asiana

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!

Very clean ,flight attendants very professional,nice , Boarding was very easy

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

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

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

Tightest knee space ever experienced on any budget airline. Crew polite and efficient, take off and arrival on time. Surprised that they did not offer water on flight except as sales product. Questions about Food and entertainment not applicable since neither are offered.

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.
