Flights from Southeast Asia to Seoul: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Southeast Asia to Seoul 
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-Sep 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.

The crew was great. There was no wifi The cabin temperature got very hot Seat was uncomfortable

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.

Staff was very courteous. Plane was clean and quite spacious even in the last rows. Veg food could have been better.

Boarding on any airline is a hot mess. Load your pivilaged passengers, then back to front. Back to front.

Problems with entertainment system eventually rectified. Cabin crew attentive and polite but a bit absent minded when it came to remembering requests, salt, sugar etc.

Very bad Instead 22 hour it take me more that 35 hour to arrive from Los Angeles to Phuket and they changed my flight in Hong Kong to Shanghai china and in order to get my bag I was forced to vet china visa entrry

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

Better. I took an aisle seat this time. Although the overheard compartment above the seat ahead of me kept opening up during flight.

Unfortunately I ended up beside a person who seemed to have been eating rotten corpses before landing because his breath smelled like Calcutta Sewage mixed with vodka and undigested eggs. Even wearing a mask that smell was so permeating that I couldn't breathe for the whole duration of the flight. I understand this is not CATHAY's fault but nevertheless I as a passenger had to endure this and there wasn't any way to fix it

Average flight for which I paid too much for on a last minute purchase.

I booked this through Travelgenio and requested a cancellation due to COVID related impact. Their customer service was absolutely terrible and they informed me after the flight had departed that they could not cancel my ticket. Worst experience, will never use them again. Strongly reconsidering using Kayak in future given how poor the travelgenio experience has been.

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.

The flight was comfortable, the food was good, and the staff were excellent. Overall a good flight.

They asked me to go down to economy when i booked for comfort class

Everything was fantastic!!!! I can’t wait to fly home 😃!!!!!

I was glad that the plane was not totally full.

Everything was very good but seats are small for a big man!

love the flight but the chairs are not comfortable mostly for smaller people

Not much legroom in economy seats and aisle. Bathrooms are not maintained well. Staff can be friendlier. Food is barely edible.

everything was excellent the crew the food, crew was extremely friendly but wish there was a tv..📺

Not leave 12 hours late. This airline is horrible always late does not refund upgrades for cancelled flights inept counter staff.. needs to be shutdown

The check in crew is rude. They are strict in luggage. How about you buy something in duty free and then they tell you to remove some of your stuff you’re ending up throwing everything. The crew are nice. But the seat is really hard it’s not comfortable in long flight. I’m not planning again to book a flight in Philippines airlines it could been better if you trained your check in crew to be compassionate and nice. I travel a lot in emirates qatar but never experienced anything like that.

I liked that we got to our destination safely. I did not like the “no” amenities. The plane was very cold and a blanket was only offered for sale. In fact the only things you could get were for sale. Food, water, snack, etc. I’m very surprised that they did not charge to use the lavatory. The seats were uncomfortable and did not adjust. My butt literally hurt after just a 4 hour flight. I don’t remember the cost of the flight, but more than $10 was not worth it. I’ll never fly Cebu airlines again. Ever!

Most passengers going to Dumaguete early are tourists who are some booked thier ferry online. Mine was wasted because of delays cause by waiting on runway before taking off and too long before they let us go down...I could still make it in time if they let us go down early. We are just there waiting to go down the plane for 10-15mins.

The seats were dirty. Food on tray table. Late on my first flight and almost an hour early on the return. My driver was unable to adjust and I had to pay for different ground transportation.

No entertainment and not expected. Cabin was very cold which brought the comfort score down

exceptionally good with the particular flight because no delay. hope that happens for every flight

Boarding had us in a tunnel with no AC for 15 minutes. Not planned well. And you have to pay for water, get at airport

The seats are too cramped, there is barely enough room to shift weight. This could be easy to endure in a one-hour flight, but not more than that. The crew did not clean up shortly after meals. The tray table remained open because of the meal and ate up what is left of the little seating space. The crew were just idling by for 45 minutes before they collected the trash. The airline did not inspect carry-on luggage. Most of the passengers brought too many bags, too large and/or over the weight limit. This undermines safety and discourages those who pay extra for checked bags just to comply with the airline regulations. If the airline is not inspecting carry-on luggage, why should I pay more just to check in some bags?

Crew was very helpful because I used a wheelchair to get around

Was denied early boarding for a hot seat row 1C. I asked gate attendant why I couldn’t I board as I paid extra for that seat and it’s privileges that come from purchasing it. and she said no that Cebu Pacific does not allow it. When I boarded plane finally I had nowhere to put my bag as the seats behind me had taken my overhead area. The flight attendant said that the gate attendant was wrong. I fly a lot in the philippines and to Japan and now I have no choice but to fly with Air Asia. At least they board with zones and allow rows 1-3 to board early.

I am 74 hrs old and I appreciate walking on the ramp instead of using the stairs. Too bad they didn’t have that on the return.
