We spent our long layover in the transit hotel in terminal 1 of Incheon Airport. The room was small, but was also very clean and well kept. I'd highly recommend this hotel if you have a long layover. The price wasn't bad at all.

Be prepared for delays and ok service. The planes they fly to Manila are usually older and not as well maintained on the inside.

I won't hesitate to fly with Korean Air again and agian....if I can get a good deal.

The flight attendants seemed to be a little more grumpy this time. A350s could use more toilet stalls.

Excellent service, love the extra amenities (water bottles, blankets, etc.).

It was horrible. The flight crew was unfriendly and the food was absolutely horrible.

So far one of the good one , whenever I go to Korea , I always use Korean airline .

They had the same movie choice as my previous flight, not much of a choice, movies were not up to date, music was uninteresting. Other than sitting on the ground for 40 minutes after boarding the plane, with pilot telling us that they couldn't load the plane because of rain, (bullshit) We finally got into Bangkok of course 40 minutes late.

Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.

The crew and my luggage was still pretty good after a long flight. They take good care of the luggage.

Really good! I like all the crew, they were so nice and very efficient.

On time departure and exceptional customer service during the entire flight.

Great service. They could offer vegetarian food and do more to reduce waste.

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

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 ☹️

My favorite airline to fly across the Pacific. The Business class lounge is fantastic, the wonderful flight attendants are helpful and professional. Great comfort while flying.

Very comfortable seats, delicious meals, and friendly and helpful staff

The flight was delayed for 2 hours, however, we flew home safely.

Everything is good, the only issue is the aircraft need to be upgraded

I recently had the pleasure of flying with Asiana Airlines, and I can confidently say it was an outstanding experience. From the moment I checked in, the staff demonstrated exceptional professionalism and warmth. The boarding process was seamless and well-organized, ensuring a stress-free start to my journey. Onboard, the flight attendants were attentive, courteous, and went above and beyond to cater to passengers' needs. The seats were comfortable, with ample legroom, and the in-flight entertainment options were diverse and up-to-date, making the flight enjoyable and relaxing. Additionally, the meals served were delicious and well-presented, reflecting a high standard of culinary quality. The airline's commitment to safety was evident throughout the flight, with clear announcements and a reassuring presence from the crew. Overall, Asiana Airlines provided a top-tier travel experience, and I would highly recommend them to anyone seeking comfort, quality service, and a memorable journey.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

The seats were more narrow than at other lines. Food was mediocre (economy class)

The crew have great customer service but their economy seating isn’t the most comfortable for a 220lbs+ guy and the food wasn’t bad, but wasn’t exceptional, either.

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

The crew and their service was top notch, but the plane itself seemed to be on the older side and worn out. Also, the food could’ve been better. 9 out of 10.

Service excellent would chose Singapore airlines as my first choice

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

ok flight, but charged for everything. water, food, baggage. no free water available, I had to plead to give me water to take medicine.

Need to consider about zero entertainment services and lack of flight information!

I can't board the 2nd flight due to the last 1st flight. In the 1st flight check-in, I can't board due to the stupid problem of K-ETA visa. The booking system and the flight company should inform the customer a few days earlier. This is the worse experience in my life. I won't use KAYAK and the airline anymore. My friends were also surprised about this stupid situation. I won't use KAYAK and T'way anymore.

I can't board the flight due to the K-ETA problem. You should inform the customer clearly a few days before the flight. I can't cancel/change the flight now. This is the worst experience in my life. I also never hear about this kind of bad experience. I won't use the booking system and the flight company anymore.

Pros: "We received great assistance at the check-in counter and were helped out even though we arrived late. The ground crew was actually great."
Cons: "We only got water. Felt like a bus ride. Minimum comfort but fair for the price."

Not a frequent user of their website booking. Booked my check-in baggage and only realized that I did not book my check in baggage for return flight. The receipt was not clear in identifying that as well. Was charged exorbitantly at check in counter. Bad taste for sure when it is a business trip and not leisure trip. Baggage was delayed for more than an hour at belt back in SG.

Boarding took forever. It's also weird that we paid more (for preferred seats) to get on the plane last. Inflight WiFi never worked the entire trip. I want my money back.

The cosmetic condition was pretty run down. The carpets were badly worn out. Even the paint on the wings was chipped and peeled! Looks like they are running these 787s to the ground..

WiFi didn’t work on both sectors so made killing time harder - planes clean modern and good flight crew - would do again if WiFi works

6hrs fly they dont give you a glass of water from seoul to singapore need to buy drink and food plus they charge for bag on international fly is always Free 1 bag from seoul to singapore is Not a local fly you are traveling true asia same story from singapore to Bali no water drink after payment for bag drink cost more the regular airline Well never use this company again we use regular company like Delta korea japan China and even scoot parent company Singapore Air

We had 2 attempts to land at Singapore Changing during a thunderstorm. Everything was delayed by 1 hour plus.

Boarding was not accordingly after front seat, bmf then back seat. This delayed for at least 40mins or more. The staff at Jakarta can do better. Is chaos at the entry to board the plane. This tarnished Scoot reputation when everyone was talking about it.

The crew was not customer oriented at all, even confrontational . The aircraft needs more attention to detail as far as comfort, and the 1 hour sitting at the gate with no air is inexcusable

We flew on the 787 Dreamliner direct to main gate at KLIA2, quick entry via eGate and on the train 41mins after touchdown. Go well SCOOT

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.
