Jeju Air Launches Japan-Korea ‘Now Cheap Sale’
South Korean low-cost carrier Jeju Air is running a limited-time fare promotion called the “Now Cheap Sale” on Japan-Korea routes, with bookings open from August 12 to August 18, 2026. One-way fares start at 14,030 yen all-in, an aggressive level for this market and a strong option for anyone planning a year-end trip or winter holiday.
A key point worth highlighting: the advertised fares are all-inclusive totals covering fuel surcharges and airport fees. LCC promotions often advertise a headline one-way price only for the figure to nearly double once taxes and surcharges appear at checkout. Here, the total is stated upfront, making budgeting far more straightforward.

App-Only Promo Code for Up to 7% Extra Off
On top of the sale fares, entering the promo code “JMW2608” exclusively within the Jeju Air official app takes up to 7% off STANDARD and BIZ LITE fares. Since the figures above are already sale prices, eligible bookings can go even lower.
Note that the code works only in the app and cannot be applied to web browser bookings. Installing the app and completing membership registration in advance will make the process smoother.
Why December Travel Makes Sense
The travel window runs December 1 to 31. December in Korea means genuine winter, with Seoul dropping below freezing, but it also brings illumination displays and seasonal experiences unique to the time of year. Early to mid-December falls in the off-season, when accommodation rates stay relatively moderate, helping keep total trip costs down alongside a cheap fare.
That said, demand spikes sharply from Christmas through New Year, and seats on those dates are likely to sell out quickly even within the booking window. If your schedule is flexible, target weekday departures or the first half of December.
Points to Check Before Booking
- Listed fares are one-way minimums and do not apply to every flight or date.
- Seat inventory is limited, and popular dates may sell out well before the booking period ends.
- LCC base fares typically exclude checked baggage, seat selection and onboard meals. Always confirm the final total before paying.
- Change and refund conditions vary by fare type; STANDARD and BIZ LITE have different rules, so review them beforehand.
- The promo code is app-exclusive and limited to eligible fare types.
Summary
With one-way all-in fares starting in the low 14,000-yen range, the standout feature of this “Now Cheap Sale” is the breadth of regional airport options. The booking window closes on August 18 — under a week. If your December plans are already taking shape, move early and stack the app promo code.
