Guide to cheap flights to South Korea this 2024

The K-wave runs strong in Singapore, with South Korea continuing to be one of the top 10 destinations that Singaporeans visit year on year. 11 million tourists passed through South Korean immigration channels in 2023, and if you’re looking to be one of these in 2024, we’ve rounded up the cheapest flights to South Korea for the year ahead.

Do note that ticket fares are always fluctuating and the stated prices are accurate at point of writing.

When’s the best time to fly to South Korea?

You might have seen or heard of the epic cold winter that South Korea experienced in December and January: if sub-zero temperatures and a white Christmas are what you’re after, definitely bookmark these months for your visit.

Outside of then, March is when you’ll find much milder, pleasant weather as the country enters into spring. Temperatures hover between 8°C-17°C, and you’re blessed with longer days, stronger sun, and the best part━just the littlest chance of rain. Expect this beautiful weather to run through to May, though it will progressively get warmer the closer it gets to summer.

March also brings the beginning of cherry blossom season, which is forecasted to begin on 19th March on Jeju Island in 2024, and a week later on 26th March in Seoul.

If autumn foliage is what you’re after, plan a trip for October and November. This year’s forecast won’t be ready till September, but as a rough gauge, the colours began to change up North at Seoraksan National Park on 1st October last year. Note that this was considered a late autumn, though. You’ll find pleasant weather around this time of the year with November being chillier.

What month is the cheapest to fly to South Korea?

For the cheapest time to visit South Korea, August is your best bet, with prices as low as $411 on Scoot, and $655 on Korean Air. 

Just a heads up: July and August are the hottest months of the year, with both heat and humidity reaching their peak. Think 30°C heat and 80%-90% mugginess, plus blazing sun and monsoon rains. FYI, these months are when half of Korea’s annual rainfall comes pouring down. 

Plus, the schools break for summer between July and August, so you’ll also be rubbing shoulders with lots of local vacationers. Besides August, March shares the podium for cheapest flights in the calendar year, while prices trend upwards starting October. Flights in December are the most expensive.

– Cheapest budget airline flights to South Korea –

1. Scoot 

Only direct flight to Jeju, from $485 return

cheap flights singapore to korea - scoot plane

Low-Cost Carriers (LCC) have made travel so much more accessible to one and all, and Scoot is our very own pride and joy, having been named the “World’s Best Long-Haul Low-Cost Airline” by Skytrax. 

They are also the only airline that flies you direct from Changi International Airport to Jeju International Airport, getting you there in less than 7 hours. You’ll have to pay for frills including baggage, food, WiFi, blankets and entertainment, but hey, it’s the quickest way to get you closer to Samdal-ri.

Do note that there’s only one flight to Jeju and back each day, 5 days a week. The flight there is a pre-dawn flight at 5 in the morning, while the return takes off at 1+ in the afternoon. 

On the other hand, Scoot flies daily to Seoul. Check carefully when you book, because SG-ICN-SG flights are only on Tuesdays, Thursdays, and Saturdays. The other flights will transit in Taipei, adding 2 hours to your flight time.

How much are tickets?
From $485 return to Jeju, or $575 return with 20kg checked baggage
From $506 return to Seoul, or $536 return with 20kg checked baggage

Another LCC you could check out is T’Way Air, the third-largest Korean budget carrier that was formerly known as Hansung Airlines. Before you shrug them off, this may be the only LCC we’ve seen that throws checked baggage and free WiFi into your ticket price.

There’s only 1 flight to Seoul each way daily, but we spotted fares that drop to as low as $50 one way━keep checking, and this could be yours too.

Flying T’Way Air will also mean you get to fully maximise your stay: the red-eye flight to Seoul departs at 2:30am, while the return flight is at 6:50pm. With 30kg of checked baggage and 10kg carry-on, you’ll be able to shop to your heart’s content. That’s not all, because T’Way Air also has USB charging ports on board so you can plug in your phone to charge as you fly.

Meals on board are priced at $14, which is pretty affordable, all things considered. Go Korean with choices such as Bulgogi Tortilla, Beef Bulgogi with Steamed Rice, and even Bibimbap. You can also pre-select your seats, with prices ranging between $5 and $54.

There is only 1 red-eye flight a day departing just past midnight, so you land bright and early to start your trip. Similarly, the return leg takes off in the late afternoon, leaving you one final push in the morning to fill your bags.

On that note, all fares on this carrier include 15kg of checked baggage. Pre-selecting seats costs from $5.40. If you upgrade yourself to their Plus or Premium Plus flight packages while booking, you can enjoy up to 58% off perks such as an extra 15kg of checked baggage, seat selections, priority check-ins, boarding, and baggage claims, as well as in-flight meal discounts.

There are 12 meal options to pick from, priced from $13.40 for a Sandwich on the Cloud. Meal highlights include Samwon Garden Braised Beef Ribs Meal ($20.20) and Samwon Garden Tteok-Galbi Meal ($16.10), created specially by Michelin Guide-recommended Samwon Garden in Seoul.

Full service airlines seem fancy, but China Southern Airlines is one carrier you can look to for all the add-ons on your flight to South Korea, at not so much more cost. Ringing in the till at just $400 this March, and $403 if you book ahead for September, that’s even cheaper than some of the LCCs that we’ve listed.

There’s no better way to land after a holiday than to that familiar refrain, “And to all Singaporeans and residents of Singapore, a warm welcome home.” All the warm fuzzies and sense of homecoming that flying Singapore Airlines brings is unbeatable, even if they do cost more than other full service airlines.

Booking yourself on Singapore Airlines gets you anywhere from 25kg-30kg of checked baggage allowance, as well as access to the exhaustive KrisWorld entertainment system spanning music, TV shows, and the latest blockbusters. 

Sign up for a KrisFlyer membership, and you’ll have unlimited free WiFi on board all Singapore Airlines flights too. They fly 4 times daily, 7 days of the week, to Seoul. If you’re still undecided about your flight, you can lock in the stated fare for an additional, non-refundable $30. This will hold your fare for up to 72 hours. 

We’ve spotted fares in the $600s as far away as November, and tickets in the $800s this December.

They operate daily, with 2 direct flights each way. Flight timings are also limited to red-eye flights there, and late afternoon or early evening timings on the way back.

Psst. While we’ve seen prices sub-$600 in March, and flights for $685 up till November. We’ve saved the best for last━at $781, Asiana Airlines has the cheapest full service flights to Seoul this December, but you’ll have to book them ASAP.
