Top tips for finding cheap flights to South Korea

  • Book at least 1 week before departure in order to get a below-average price for flights to South Korea.
  • High season is considered to be July and August. The cheapest month to fly from the United Kingdom is January.
  • Enter your preferred departure airport and travel dates into the search form above to unlock the latest South Korea flight deals.
  • 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.
  • 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.

Crew, service and food are excellent. Boarding could be better. Eg use the sign, in addition to calling

Pros: "The crew were good and very pleasant."
Cons: "The food was pretty gross. I don't know how you can pass that for food."
Pros: "All crew was super polite, friendly and professional, the food was amazing, and seat was comfy."
Cons: "The entertainment was poor, bad movies selection, small selection of movies, old movies."
Pros: "Great crew, good food, easy to watch entertainment , and food better than most airlines"
Pros: "Great service"
Cons: "Hope I can change seat when I check in even though I choose to enter other skyteam number than sky pass."
Pros: "Excellent service and probably the most efficient boarding process I’ve ever been a part of. Food service went by without a hitch, and the stewardesses knew English very well so we felt comfortable and welcomed. I also really liked being able to get terminal/travel information from the infotainment system. Being that I’ve never been to ICN or NRT before, having access to terminal maps and basic instructions on how to find connecting flights and baggage claim areas was probably one of the most helpful features of the flight!"
Cons: "I am 5’11” and found my seat somewhat uncomfortable. It didn’t detract from being able to sleep at all, but it did seem like the seats on this airline might be at its most comfortable with shorter passengers."
Pros: "Flight, weather, crew interaction was all great."
Cons: "They dont give us socks for our feet or tooth brushes or mints or anything. One small bottle of water for a 15 hour flight doesnt cut it, sorry! This is one CHEAP AIRLINE!"
Pros: "Very clean and polite flight crew."
Cons: "I wasn’t able to choose my seat at 24hr check in so I was stuck in the middle and getting out was awkward as I would have to wait for person in aisle seat to eat, wake up or get up themselves."
Pros: "Nothing our tickets had to be cancelled"
Cons: "Our flight was scheduled with Korean air. We attempted to check in multiple times with issues on the Korean air website. we called and they told us not to worry. Finally, approximately 12 hours before departure we wwere able to check in Only to find out due to the expiration date of our passport we would not be an allowed to check in. We scrambled to get an emergency passport, however by the time it was received we had already missed our flight. Korean air is not willing to aknowledge this as a fault in their system and is instead suggesting this is a kayak issue for allowing us to purchase these flights. I would like the total flight cost refunded as this should never have been allowed to be purchased if Korean air knew at the time of purchase when checking in there would be an issue."
Cons: "Crew's English skills could be better. No wifi or other connectivity options on a 13 hr flight."
Pros: "They were able to fly us out of Incheon to JFK even there was only less than 10 passengers."
Cons: "Could not ask for more."
Pros: "Had a row to myself, crew was extremely attentive. Due to a lack of passengers, the crew was even able to anticipate many of our needs before we voiced them."
Cons: "My first headphones didn't work and the pull out tray in my row had a bit of left over food crusted on to it."
Cons: "The flight was late for three hours and as a result, we missed our connection to Hawaiian Airline and have to spend the night in Korea. They never explain why the flight was late and no apology was given"
Pros: "Seat comfort and service"
Cons: "Cabin temp too warm; mediocre headphones (bro f your own)"
Pros: "The service was nice, they had good food and enough meals unlike some airlines."
Cons: "I was uncomfortable and couldn’t sleep so I can’t give this flight full stars, but I can’t really blame anyone either. Wish there more more movies to take up some time."
Pros: "Excellent ethnic Korean food. Attendants were extremely polite and and professional."
Pros: "Flight attendants were very friendly, greeted everyone with smiles. They seem to accommodate most requests, just be polite! There were a few people on my flight that were not the most friendly to them, but the attendants still tried to help as much as they could. Food is pretty good. I mean, don't be expecting a 5 star meal, it's still airplane food... International flight so I got 2 free checked bags, which was really nice."
Cons: "It's a small thing but the Chinese and Japanese movies only have Korean subtitles, it'd be nice if they had English too. Deplaning - the only exit is from the front of the plane, so it takes a while because there's 70-something rows of passengers."
Pros: "Crew was attentive"
Cons: "Food was sub par and I flew TO Manila on the flight - the discrepancy in the food quality was very different. Entertainment is dated and for such long flights very limited compared to competitors."
Cons: "The food. Aused from the serving size, only 2 meal and 1 small snack served for the whole 12 hr flight. Got my gastric pain acting up. FA wasn't also very pleasant. Toiletries wasn't replace when they ran out especially d papers for seat covers."
Pros: "Our flight is only Incheon to Narita and later that night our final destination is LAX. I have checked in to Singapore Airlines the day before our flight. While checking in at the Incheon airport, the ground attendant ask me for my final destination. After a few minutes, shw mentioned that our baggage will be picked up at LAX. I was so relieved since this trip was 3 weeks with 3 50lbs luggage and 2 10 lb backpacks. I imagined going to Japanese Immigration again and explaining the reason for the entry. Because of this our layover is seamless. Star Alliance made it so easy for us to take their airlines anytime. Kudos to Star Alliance. Oh, the legroom is roomy for Economy! Nothing can compare with their airbus. I am only 5foot1inch and its like having a lounging chair. My husband whose 5’10” is happy with the space. Thanks for thinking of your passengers!"
Cons: "It is minor thing only. Their headphones does not work. Which is not an issue since I always bring headphones and buds for our long haul flights!"

One of us was moved to a middle seat, which we didn't expect. Not a big problem, but not the seat we had reserved. Intercom volume was low, making it hard for us Americans to understand the captain's announcements in English. Appreciate the captain announcing when we were flying over Lake Como.

Pros: "Plane was empty so got a whole row to myself!"
Cons: "One flight attendant in our area was not friendly and quite abrupt. Food wasn't good but desserts were great. American movies were a bit old."
Cons: "The only company that constantly delays flights. Narrow and uncomfortable places in the business class. They waited 4 days for the suitcase! They are not responsible for receiving compensation for the delay in suitcases! Where to write and call?"
Pros: "Lufthansa hands down is the best airline I have ever flown!"
Pros: "Tv screens, free beverages, frequent service"
Cons: "The single most cramped and uncomfortable flying experience of my life. The chair in front of me recliner lined to 4 inches in front of my nose. Couldn’t move legs or arms for 10 hours because it was so tightly packed. I couldn’t believe it was legal to fit that many people that closely together."
Pros: "Crew was excellent"
Cons: "Food was horrible. Breakfast consisted of a dry muffin and an oreo cookie"
Pros: "The flight was on time. The cabin crew was helpful and very friendly and the food was the best we have recently had on an international flight. The entertainment selection was enormous and spanned the realm of all venues."
Pros: "Nice plane, free checked bag, and a snack,"
Cons: "Left 20 minutes late as the copilot was late, middle row seat (as I refused to pay the seat choice charge, (and it was only a one hour flight.)"
Pros: "This was my first experience flying with Lufthansa airlines and the experience was outstanding from start to finish! This is what flying should be like! Other airlines should do what they do!"
Cons: "Nothing"
Pros: "Lots of legroom"
Cons: "As with most long-distance flights, the bathrooms got somewhat dirty though I did notice flight attendants on two occasions entering to clean them"
Cons: "Boarding at LAX was one hour late. And the lines were chaotic and very disorganized."
Cons: "Din’t be almost 4 hours late No explanation, no apology"
Pros: "2 hour delay, which had a quick transfer. My bag did not arrived with me. I submitted a luggage claim, they were supposed to call me up the following day which they didn't. I took it upon myself to go to the airport to collect my luggage. It took half day to take care of the luggage situation."
Pros: "The entertainment selection"
Cons: "Seats were brutally uncomfortable. It was unbearably hot the entire flight because the air was not turned on. And there was not the advertised amount of legroom."
Pros: "Great crew, fantastic entertainment. Spacious leg room even in economy."
Cons: "N/A"
Pros: "New gate number already established on the live update screen while printed still with old (three flights in three weeks - same airport/airline ad same story). Crew misinforms about the gare number too. Very confusing for the 75-year-old. Luggage lost, entertainment poor, plane late"
Cons: "people were nice, other than that logistics poor so work o every aspect"
Cons: "Enough of LOT. For a couple hundred bucks more you get a much better trip. LOT is the no frills discount line."
Pros: "Crew was amazing.Seats are comfortable.Clean aircraft.Friendly service."
Pros: "The cabin staff was very friendly and attentive. The boarding process was efficient (the long time it took was owed to the large crowd entering the plane in a Boeing 787), the entertainment programme is not overwhelming, but adequate."
Cons: "The flight was delayed by almost three hours at a most uninspiring airport. The information on the delay came rather late. Although I managed to reach my connecting flight, my luggage did not. (It was sent after, though, with the next machine and reached my late the same night in the hotel.)"
Cons: "- Boarding: was rainy and is quite complicated when you need to take the bus; All the other difficulties were more related to the weather. However, for a ~260 EUR flight, the lack of comfort and basic food were unexpected."
Pros: "I do get what some other reviewers are saying. The food was just fine, better than some airlines but no worse for sure. The crew was excellent and attentive, and i'm saying these things not having had the benefit of the CHEAP flight noted by the previous reviewer. I'll be flying with these guys again."
Cons: "The same gripes everyone has about airline experiences, it's cramped, x 15 hours."
Cons: "They did not have a vegetarian option available to me on board. They should have offered bottled water for a a flight this long to avoid dehydration. Also my entertainment system was faulty. It didn’t offer a wide selection of movies and halfway through the flight or completely shut down. I couldn’t even listen to music or track the flight. Staff also had difficulty understanding my English so I gave up on communication."
Pros: "On Time departure. Attentive crews."
Cons: "It would be nice to see a smiley faces from all the cabin crews while providing services."
Pros: "There was nothing particularly remarkable"
Cons: "I wished that the TV screens were positioned such that the screens were clearly visible from all seats."
Cons: "I selected middle and window seats for each flight so my girlfriend could rest her head on the window and sleep. We were given middle seats and aisle on each of our flights. It’s fristrating that I paid extra to book the seats we wanted and we did not get them."
Pros: "A solid overall airline. Nothing extraordinary, but will get you to where you need to go comfortably."
Cons: "Nothing stands out as obvious, but it’s simply apparent the airline isn’t flying big spenders."
Pros: "Fav in crew inattentive/ and reluctant to enforce any airline guidelines"
Cons: "They don’t serve water regularly, only before meals. No snacks between meals. My screen does not work. The crew seems not quite nice."
Pros: "Service Crew superior performance to passengers. Very attentive."
Cons: "I had one luggage which was long delayed in coming out of the airport luggage arrival carousel even if I am a Business Class passenger"
Pros: "Seats were ok. Downloaded media for each seat was diverse and entertaining. Food was alright."
Cons: "Crew was pretty curt and not polite. They also 'didn't have time' to load my bag onto the plane, along with ~15 other people. I had to wait two days for it to arrive. 'No time' to load bags is kind of an odd and slightly unacceptable reason to not load baggage onto a plane. Airlines close check-in for flights 30 mins before departure time to ensure that all bags make it onto the plane. I was 3 hours early. Don't know why they 'didn't have time'. They also broke my friend's bag."
