Flights from Southeast Asia to Incheon Intl: the best tips from KAYAK users

Insights shared by verified travellers who flew the route from Southeast Asia to Incheon Intl 
Verified travelerFlew with Korean Air-Jun 2025
Check in early to get a good seat assignment
Verified travelerFlew with Asiana Airlines-Jun 2025
Do not check a suitcase take a carry on
MariaFlew with Asiana Airlines-Dec 2024
If you're flying into Ho Chi Minh with a different airline, make sure you have printed tickets because security does not accept mobile tickets (only printed) and hopefully other airlines are better than Asiana otherwise, plan to spend several hours in the transfer area with nothing available other than bathrooms.
Verified travelerFlew with Hawaiian Airlines-Sept 2024
I will not fly to ICN and transfer to Hawaiian again. Both Asiana and KAL are good flights to ICN. And their lounges are both good. But if flying onward, stay with Asiana or KAL connections. ICN doesn’t do terminal connections well.
ArthurFlew with Delta-Jul 2024
Make sure to select an aisle seat. Korean Aur flight attendants are. very nice and try to help . My overhearing light was broken !
Verified travelerFlew with Cebu Pacific-Apr 2024
Do not take a budget airline next time. If there is no choice but Cebu Pacific, then don't pay for checked bags. Just bring a huge backpack, a carry-on suitcase, and one big handbag (personal item) up to 10 kilos each. Cebu Pacific does not care about these things anyway.

Excellent. All well and accommodating. Clean and very good food. Peaceful travel experience

The food wasn't to good but the crews were great, clean plan clean bathrooms always

Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Never had a flight delay issue with Korean Air, that's why I always go with this airline.

Flight crew were very attentive and made this trip a pleasure. Plus the fact that this our first time flying business class.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

On schedule, courteous, and efficient. Old aircraft with not so nice lavatories.

Really great service throughout and the food was really nice. I can highly recommend thank you very much.

Fast and efficient flight. Wifi worked well. Food selection could have been better

It was okay. I feel that Singapore Airlines isn't as good as it used to be but it's still not bad

I felt that the whole experience went very smoothly. The aircraft was extremely clean and tidy on boarding. The cabin crew were beautifully turned out very, very efficient and were a credit to Singapore Airlines who are now my favourite carrier.

I have difficulties to book wheelchair for my parents returned flight

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

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.

Very good customer services before, & during flight. I will choose it again in the future.

Wouldn’t let us check our stroller and car seat at the gate

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.

Flight was delayed from 8pm to near midnight. They made us board then sit in the cabin and wait for even longer for take-off. No compensation whatsoever - not even in a free drink or meal

Very quick turn around, plane was in good condition, alles paletti.

Premium check in was worth it. Boarding process was a little chaotic. Seats were super cramped and I am less than 80kg and 180cm

It was good. The FACE check in at KLIA2 was not working.

The flight delay... but bus from the airport be on time

They didn't have a single blanket for hire for a long haul overnight flight. This wasn't good enough even for a budget airline

Kayak shares with you the best price! and in my case it was Air Asia flight. Air Asia flight was on time, the boarding was seamless with FACES technology at KLIA2 and the pilot made a great smooth landing upon arrival. Excellent trip!

It’s THE worst international flying experience I have had. I will avoid this airline.

The crew is good, but the flight delayed and there is two passengers keep talking during the flight

I don’t fly also same as previous no refund even it’s airlines or agency mistake

“They carefully called each boarding group in turn, only to herd everyone onto a bus for the drive across the airport apron. By the time we reached the aircraft, all semblance of orderly boarding had disappeared and it became a complete bun fight to get on board. Rather nonsensical really — why bother with boarding groups in the first place?”unless you are at an air bridge!!!

Boarding was not as per sequence Light snacks were not available Window had hair oil stains and water condensation

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.

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.

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..

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

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.

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.

Connection flights are smooth, both flight takeoff arrive on time, that will be the best u can expect. Food no order, service no complain, entertainment not seen, cleanliness can be improve.

Instead of the flight attendants talking to each other they should have been monitoring the passengers. The person beside me took a phone call literally 30 seconds before the plane landed. As we were going down the runway ( from landing ) a person in the row in front of me and behind me made phone calls; CRAZY
