Seoul in winter is a postcard: steaming street food, glowing lantern displays, snow-dusted palaces and ski resorts just a train ride away. It is also one of the most popular choices for an overseas trip for winter among Malaysian travellers, which means flight prices can climb quickly.
So when do flights to Seoul actually get cheaper? This price guide explains the seasonal patterns, which dates tend to cost more, how far ahead to book, and how to compare fares on Trip.com. It is written for the 2026/27 winter season, which is close, so you will also find tips for booking on a shorter timeline.
Note: Airfares move daily and depend on route, airline, demand and fare rules. This guide describes general patterns, not guaranteed prices. Always compare live totals before you pay.
Quick Summary
- Cheapest windows are usually outside school holidays and public holiday peaks, often early December, mid-January and the weeks right after Seollal.
- Most expensive periods tend to be Christmas and New Year, Malaysian school holidays and the Lunar New Year (Seollal) week.
- Midweek departures are often cheaper than Fridays, Saturdays and Sundays.
- Compare the total fare, including baggage, seats and meals, especially on low-cost carriers.
- Check a current Trip.com promo code and compare dates in the flexible-date view before booking.
Why Seoul Flights Cost More in Winter
Two things push prices up at the same time:
- Strong demand. Winter is a peak travel season for Seoul, thanks to snow, winter festivals, skiing and shopping sales, and the year-end holiday period.
- Overlapping holidays. Malaysian school breaks, Christmas, New Year and Lunar New Year all bring extra demand from different traveller groups.
Because Seoul is a long-haul route from Malaysia compared with nearby Asian cities, fares are more sensitive to peak demand. A few days’ shift can change the price noticeably.
Winter Flight Price Calendar: What to Expect
The table below shows general patterns for Kuala Lumpur to Seoul flights. It uses relative price levels rather than specific figures, since fares vary year to year.
| Period | Typical price level | What is happening |
| Early to mid November | Moderate | Autumn leaves fading, early winter chill, fewer crowds |
| Late November | Moderate | Pre-winter shopping, early lantern and lights events |
| Early December | Often lower | Quieter period before Christmas rush |
| Mid to late December | High | Malaysian school holidays and Christmas travel |
| Christmas to New Year | Very high | Peak demand for both flights and hotels |
| Early to mid January | Often lower after New Year | Cold at its strongest, fewer holiday travellers |
| Late January | Moderate to rising | Demand builds ahead of Lunar New Year |
| Seollal and Chinese New Year week | Very high | Major holiday in Korea and across Asia |
| Mid to late February | Often lower again | Post-holiday dip, still winter conditions |
If you are flexible, the best value usually sits in the gaps between these peaks.
The Cheapest Times to Fly to Seoul in Winter
Early December
The window before Christmas and school holidays can be a sweet spot. Temperatures are already cold, holiday lights are starting to appear, and fares are often lower than the festive peak. Departing midweek can help even more.
Mid January
Once New Year travel ends, demand often drops before Lunar New Year ramps up. This is typically the coldest part of winter, so pack accordingly, but fares and hotels can be easier on the wallet. Winter events and ski season are in full swing.
After Seollal
After the Lunar New Year holiday, flights often become more affordable again. It is still cold in Seoul, though you may see hints of the season changing by late February.
The Most Expensive Times to Avoid
- Malaysian school holidays in December. Families fly together, so demand is high.
- Christmas to New Year week. Peak pricing for flights and hotels.
- Seollal and the Chinese New Year week. Both Korean domestic travel and regional travel surge.
- Weekend departures and Sunday returns. These are commonly pricier than midweek.
If you must travel in these periods, book as early as possible and consider flexible dates around them.
How Far Ahead Should You Book?
There is no perfect rule, but these guidelines help.
- For peak dates: Book as early as you can, since seats and cheaper fare buckets fill up. Two to four months ahead is a common target for long-haul peak travel.
- For shoulder dates: A few weeks to two months ahead may be enough.
- If you are booking late: Since winter is close, check several dates, airlines and nearby airports, and be ready to decide quickly when a fair fare appears.
- If your plans may change: A flexible fare can cost more upfront but may save you from change fees.
Trying to wait for a last-minute bargain on a peak route is risky. Prices tend to rise rather than fall as popular dates approach.
How to Compare Seoul Flights on Trip.com
Trip.com’s search tools make it easy to compare options in one place.
- Search Kuala Lumpur to Seoul (and try nearby Malaysian departure airports if relevant).
- Use the flexible-date or calendar view to compare prices across nearby days.
- Compare airlines and fare types. Full-service airlines often include baggage and meals, while low-cost carriers may charge separately.
- Check direct vs connecting flights. A cheaper connection may add hours and risk, especially if tickets are separate.
- Compare the total price after baggage, seat selection and fees.
- Set a price alert if you are not ready to book yet.
- Apply a voucher before paying. Try a Trip.com voucher code or a Trip.com discount code and confirm the total drops.
- Read the fare rules, including baggage, changes and refunds.
Using promo codes on Trip.com
A coupon can lower your final price on eligible bookings, though conditions vary. Typical restrictions include:
- Minimum spend.
- Specific products or routes.
- New-user, app-only or payment-method limits.
- Limited validity and redemption caps.
Check the in-app coupon section and a page that gathers current offers, such as the Trip.com promo code page, so you can see what is available before checkout.
Low-Cost vs Full-Service Airlines
| Option | Pros | Watch out for |
| Low-cost carrier | Lower base fares, flexible add-ons | Baggage, meals and seat fees can add up |
| Full-service airline | Baggage and meals often included, more comfortable on long flights | Higher base fare, especially at peak |
| Connecting itinerary | Sometimes cheaper | Longer travel time and risk of missed connections |
The cheapest base fare is not always the cheapest trip. Winter clothing is bulky, so you may need more checked baggage than usual. Add that to your comparison.
Don’t Forget Other Winter Costs
Flights are only part of the budget.
- Winter clothing: Thermal layers, a proper coat, gloves, a scarf and warm shoes. If you do not own them, factor in the cost or consider buying in Seoul during sales.
- Accommodation: Winter peak dates also raise hotel prices, so compare packages and book early.
- Local transport: Seoul’s public transport is efficient and affordable, but airport transfers and day trips add up.
- Ski trips and festivals: Resorts and events may have separate tickets and transport costs.
- Travel insurance: Worth considering for winter weather disruptions.
- Entry requirements: Check the latest visa and electronic travel authorisation rules for Malaysian passport holders before you book.
