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 AirCRK-ICNJun 2025
Check in early to get a good seat assignment
Verified travelerFlew with Asiana AirlinesBKK-ICNJun 2025
Do not check a suitcase take a carry on
MariaFlew with Asiana AirlinesSGN-ICNDec 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 AirlinesBKK-ICNSep 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.
Verified travelerFlew with Cebu PacificMNL-ICNApr 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.

This was an amazing flight. The crew was great. The service was great. The food provided was great.

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

Korean air has a little bit more seating space than Asiana air.

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Unfortunately, there has been a boarding and departure delay. However, as usual, the flight arrived earlier than the scheduled. There has been a turbulence in-between, it’s unavoidable. I couldn’t complain them.

Not many people, so you can lay down on two seats

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

The food on this flight from NRT to ICN was average. The staff were very friendly, but the flight took about 60 minutes longer than it should have because the pilot was only flying at 330mph instead of 500-550. Not sure what the reason is for that, but it meant for a much longer flight.

Flight delayed going to Korea. No free WiFi. Other than that everything else is were good. I would love to fly with Korea airline again

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.

Cons: "Sold me a ticket then cancelled 15 minutes later due to not having updated information from the airline on bookings."

I had excellent experienced flying with Cebu Pacific on my domestic flight. However, no food and beverage serve might be due to short travel time of 40 minutes.

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

Your check in lines were terrible everything else was great!

flight cancelled.. booked through orbitz, yet orbitz won't handle refunds.. never use them again..

It arrived 18 minutes early. Attendant are good. For baording , they should improve especially carrying thru bus.

Super delayed. Delayed to get the bus, delayed to get off the bus, delayed to take off.

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

Kind of worried due to typhoon but yeah we can't do about nature thing. So okay naman kudos to all crews and pilots for the safe landing.

it was good experience though we wait for a minutes in the railday due to no available parking. Keep it up all..

Not a good experience. They did not have the food I ordered in advance. The crew is not offer a second snack on a 5 hour flight. The WiFi was either not working or was very difficult to connect to.

The flight was delayed by an hour . Traveling with 75 year old father was difficult and then when he asked for water he was asked to purchase :-) . Overall just an ok experience.

Overall service is good, the only thing I would like airasia to improve is there seating. Their seat handles are broken as well as the back rest

Boarding with air asia is excellent via organized lines by zone except when there is only 1 gate agent and no scanner, only by tearing tickets??? Crazy

The flight was supposed to depart at 9:25. It departed at 9:00. Im glad we were early and did not miss it.

They wouldn't even allow us to bring water from the fountain on board the aircraft.

Premium seats should have legroom this one didn't have it. I had 2 free checked bag but I got charged for while it shows on my reservation

Terrible airline! This airline just ruined our family vacation due to a 12 hours delay as a result of their operational issues.

Too many flight delays. Airport terminal serving Boracay needs upgrades.

Over 6 hours delayed.. using philippine air fleet planes are beat up dirty and uncomfortable. Have been flying air asia for over 4 years from Manila to Tokyo and kansai as well as several local flights from Manila to Bacolod and Cebu.. 3 planes were down for maintenance and caused havoc.. need to invest in new fleet or seriously clean and upgrade the existing fleet. Will not be flying anymore until fixed. Several options out there now to choose from as air asia prices have skyrocketed.. no point in using them anymore . Severally upset passenger here. They can’t even manage the queuing of Zones for boarding as it’s a crab fest free for all now. No discipline and let the passengers in line to board just run into any lane possible.. and priority luggage?? Forget it I’ve paid for it for the last 6 flights and never got it first.. air asia has turned into a expensive joke.. use Cebu pacific or zip air now..

The flight was OK, but you need to warn passengers going to Vietnam that the full first, middle and last name needs to be in the issued visa, At least 5 passengers on that pane did not have that. We all had to pay $298 each to some agent to amend the visa. At least one lady could not and was left behind.

VietJet is a discount airline like EasyJet, Flair or Spirit. I flew 3 flights in 2 weeks and all were Airbus 321's. 2 of the flights left and arrived on time and 1 left and arrived about 45minutes late. Seat pitch in economy is 29" but exit row seats have super-generous leg room. There are no power ports or entertainment of any kind. Food is best purchased on-line before the flight but there is a limited selection available in flight - cash only. The aircraft are clean and the airline is run as well as any other airline that specializes in economy passengers.

Our flight was 3 hours delayed and the airport was hectic as our boarding pass said one gate while the digital screens said another gate. Attendants were clueless and said to watch both! Vietjwt cared more about selling their merch than even providing any water for the 2 hour flight

Cheap flight but more expensive when the airlines demands you pay over 30$ for 1 kilogram overweight ( it is 8,2kg I have for carry on baggage) The flights announcement 2PM, and it departed 4 PM, no announcement for delaying, People says Vietjet is delayJet airlines in their blood.

Vietjet tried to steal extra money from passengers by forcing them to change the name on the ticket that was correctly filled in on an English form online when ticket bought online. I bought the ticket via a foreign website where the language is English, At filling in the passenger's name, it says middle name first, then first name, and last name, That the ticket done and printed. when my wife checked in the staff at the check in counter said that her name was written wrong, she must fill the name in Vietnamese style, writing the Last name first, then middle name, first name comes last, even though her name was not misspelled. At the aiport I asked the Vietjet customer service, if it is written in Vietnamese way, it will be wrong when she travel abroad ? The custom service could not answer. It took over an hour where my wife was thrown like a ball between the check-in counter, to the Vietjet customer service , then to passport control. The cost is 110,000 vnd for change place in vietnamese way, I thought if there are millions of passengers who have done the same mistake, how much money Vietjet raked in every year On the flight, it is not allowed to sit in the empty seats in front or next to me, I sat in the middle in a row where two big men were sitting, I really need to change seats but the crew asked to pay extra to buy the empty seats. It is petty and cruel of Vietjet. There is no other choice than the state-owned airline, then you have no choice but to swallow the bite

Our flight was delayed for about 3hours however the ground crew made it sure that we will not miss our connecting flight from Hanoi to incheon.

If there could be simple free food or snack or some entertainment.

Seat pitch is narrow moreover the agent assigned seat in front of emergency exit window which is not reclined. A terrible 4hr 40min flight from HAN to DPS

Horrible! As an Asian, they look down on their own skin color. Disgusting people and airlines. If you are white, they will worship you

1-Airlines did not send any info to inform the clients about changing fight number. 2-Delayed too long on runay without any explanation
