You have to prepare for the waiting time for immigration to Vietnam, it takes 3 hrs to go thru and it is easy to get mad of it
TomFlew with Asiana AirlinesICN-CGKJul 2024
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 loved everything, I was just a little confused on my bag allowance. When I checked in it said I was allowed 2 check in bags, but when I got there they said I was only allowed 1 so I had to pay an additional 200 dollars! Other then that everything was great! I would love to use your Airlines again when I fly out to Manila again in late May, however I want to be able to have 2 bags included this time lol 😆

An International flight from Cebu to Incheon was delayed the night before without a proper explanation. Same thing happened from Incheon to Cebu in the first leg. I will not fly Korean again. And I will ensure Delta their US partner hears about it. This is a routine by Korean to delay flights from and to Cebu via Incheon.

the water for tea could have been hot, entertainment was awful, lots of old movies and TV shows

The carry on baggage was collected before boarding without further information where the passengers can collect them . When the flight arrived at Tan son Nhat airport, it was very complicate to find the luggage

I like it when the plane have waited for passengers like us who are trying to catch the plane. Detroit was my mom's port of entry we spent too much time looking for our luggages at baggage claim which no problem. But then the problem occur after the immigration when the homeland security agents forgot to give us our passports which it took so long to find them and I was very anxious because we might not be able to catch our flights but luckily the plane to knoxville still sitting there and waiting for us. Praise the Lord for everything.

They changed aircrafts and they moved my seats that were already prepaid. I did not get the seats I paid for, so I got expensive seats that I didn't want

The flight was at least 3 hours late with not much of an explanation other than connecting flight was late

Good. Obviously there is a slightly condescending attitude of all American workers towards their customers but other than that all good.

Thanks for fixing the title of this question... the flight was a DELTA one marketed as a Korean Air flight. Which automatically makes it worse. The crew were actually rude in several cases and clearly lacked cultural sensitivity to the majority of the passengers (Koreans). This flight was also a minor heart attack before it started. Firstly, I thought I was buying a flight from Kayak, but it turns out they just acted as a front for this other company, UnderPricer, which took almost 24 hours to send a proper confirmation of the flight. We could not select the seats at checkout time either. We later submitted our seat selection to Korean Air, who proceeded to mess up the instructions to Delta, so our family was separated on the flight and our aisle seat was replaced with another middle seat.

It was a great experience in all aspects including passengers are respectful to each other. I will consider to fly with Korean Air again in the future.

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

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

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.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

It was very good experience on board to Sydney with SQ.

Everything was great keep up the good work 😁, can't ask for more.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

The food options and quality could use some more excitement and variety.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

I was a member of Krisflyer for ten years, but my last flight to Tokyo was a disaster. I had to stand in line for four hours before check-in because they were late opening the counter, and there were more than 50 people behind me. The plane was extremely small, and the food could have been better. When I dropped off my stroller before boarding the plane, I expected to receive it upon exiting for my transfer. However, they returned the stroller to the checked baggage because they said I was late getting off the plane. Of course, I was late; they assigned me a seat at the back of the aircraft, and I was traveling with a baby! The worst part was when I arrived in Jakarta. They damaged my stroller and refused to approve my claim, so I had to pay for stroller rental because of the damage they caused. I don’t know what happened to Singapore Airlines, but I felt like I was flying with a budget airline.

Finishes were quite worn, including our very scratched up seatback. No entertainment available, and the WiFi (even for “ScootHub”) was very slow. Crew were somewhat friendly.

Food & lower the prices. Look at Air Asia food look better & affordable

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

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.
