Top tips for finding cheap flights to South Korea

  • Enter your preferred departure airport and travel dates into the search form above to unlock the latest South Korea flight deals.
  • South Korea has a number of international airports that provide onward connections to other destinations. Incheon International Airport (INC) in Seoul, in the north of the country, is a good hub if you want to explore the northern region and has many domestic connections to the rest of South Korea. You might consider flights into Busan if you are planning to visit the southern regions of South Korea.
  • If you are looking at flights to South Korea so you can visit the UNESCO World Heritage site of Jeju Volcanic Island, you should consider booking a flight to Seoul and then making an onward booking to Jeju International Airport (CJU), which is located on the island. You can then make your way into the Hallasan National Park by road to explore the volcano.
  • If you plan to hire a car, it is important to note that Korean law has made it mandatory for children under the age of 6 to use a child car seat – this seat can be hired with your car or you can travel with your own. If you plan to take a taxi from the airport, there are certain taxis that will have child car seats, but this is not true for all of them, so you may wish to travel with you own seat for safety reasons.
  • There are ATMs and bureau de change counters at the main airports in South Korea, so you will be able to obtain your local currency upon arrival in the country. Most taxis in the Seoul area will accept major credit cards, so you do not need cash to take a taxi from the airport to your accommodation. However, if you are travelling outside the main hubs via road, you may need cash to pay for taxis.
  • If you want to visit the centre of South Korea to do some hiking in the mountains, you could consider booking a flight to Daegu International Airport. From here, you can transfer by rail or road to some of the attractions in the region, such as the Palgongsan Natural Park.
  • A very popular destination in South Korea is Seoul. Visitors head to Seoul to experience over 500 years of Korean tradition, at places like Gyeongbokgung, Deoksugung and Gyeonghuigung. To explore this region, fly into Incheon International Airport (ICN). Frequent flights from London leave from London Heathrow Airport (LHR).
  • When flying to South Korea, you may need to buy a local sim card when you arrive. Look for providers such as KT and SKT in the duty-free areas. Sim cards are cheap and essential for local apps to get around the country and to find places to eat, accommodation and local attractions.
  • An easy way to get around South Korea is via public transport. At most arrival airports in South Korea, there are bus, rail and taxi options. At Incheon International Airport (ICN), the train station is in T1 and has an express train service. The bus station is in T2. You can purchase tickets at the station, and you'll also have access to taxis from there.

Aircraft is pretty old. Seat is not comfortable. Meal quality is disappointing. Entertainment system is not impressive at all.

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!

I normally love Korean Air, but this trip was not great. We boarded the plan and were settling into our seats. My son and I use these leg swings and we used it on the trip over to Cambodia, but on the way back the flight attendant very rudely told us we could not use it and that it was against regulations. I asked to see the regulation, but never saw it. The food on this trip was horrible as well, Even my son's kids meal was disgusting so we didn't eat anything on the flight. Thankfully we brought snacks. Entertainment - what happened to the games?

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

I am thankful that I was able to fly using Asiana

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

Seating and zone. The minor I went with didn’t even seat close to me

My seat 3G did not go down fully and the buttons were not working properly

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

The meals were not the greatest and lacking of appetite but everything else was spot on

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Had a delayed flight that caused me to miss all of my flights. Supposedly I was rebooked. When I got to my next connecting flight there was no ticket for me. I spent hours working with an agent. And they still couldn’t get it right. I will arrive home more that 24 hours later than my original schedule. Totally inept and frustrating experience.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

Bumpy ride, not Lufthansa‘s fault. Crew managed a situation over a back rest to far down well. It was two iles behind me. The person putting the seat down, against the other person’s knees, was quite rude and belligerent and needed to be told in a no nonsense matter to stopp. Male flight attendant did good job.

It was very good. Service was friendly and efficient, and food was good.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

We were upgraded to economy plus and everything was awesome!

The plane was late (as was my flight out from Birmingham the day before)

The flight was delayed by an hour. Made the connection uncomfortably tight.
