Jeju Air Launches All-Route Sale on Japan-Korea Flights
South Korean low-cost carrier Jeju Air is holding an all-route sale covering its Japan-Korea network from September 7 to September 15, 2026. Every Japanese route operating to and from Seoul and Busan is included, with one-way total fares starting at just 12,530 yen. The promotion applies to the STANDARD fare, which includes 15kg of checked baggage, making it a practical option for travellers who plan to bring a suitcase.
Fares Include Fuel Surcharges and Airport Fees
All prices announced are total fares including fuel surcharges and airport usage fees. Low-cost carrier sales often advertise base fares only, leaving passengers with a much higher figure at checkout, but here no additional taxes or fees are added on top. The STANDARD fare also bundles 15kg of checked baggage, removing the need to pay separate baggage charges. Measured against real trip costs, the value is even stronger than the headline price suggests.

One-Way Minimum Fares from/to Busan

Regional Cities Offer the Best Value
The cheapest fare in this sale is Matsuyama at 12,530 yen, followed by Hiroshima at 12,600 yen, Kagoshima at 13,430 yen and Oita at 14,230 yen. Regional Japanese cities dominate the top of the price list. Once you factor in the domestic transport cost of travelling to a Tokyo or Osaka airport, these fares dramatically lower the barrier to an overseas trip for residents outside the major metropolitan areas. Even so, Tokyo/Narita at 14,470 yen and Osaka/Kansai at 15,770 yen keep big-city departures in the 14,000-16,000 yen range. Hokkaido and Okinawa routes are naturally higher given the distance, but at 18,150 yen for Sapporo/Chitose, 20,730 yen for Okinawa/Naha and 20,800 yen for Hakodate, a return trip to Korea remains achievable for around 40,000 yen.
App-Only Promo Code for Up to 30% Off
Booking through the official Jeju Air app and entering the promo code W26TABI7C unlocks up to 30% off. The benefit is app-exclusive and cannot be applied to bookings made on the website. Because the discount can stack on top of the minimum fares listed above, travellers chasing the lowest possible price should book via the app. Note that the actual discount rate varies by route, flight and booking class.
Sales and Travel Periods
The sales period runs from September 7 to September 15, 2026, with a travel period from September 8 to December 31, 2026. That window covers the autumn travel season through to the end of the year, suiting autumn foliage trips to Seoul, food-focused getaways to Busan and year-end shopping breaks alike.
Points to Note Before Booking
- Listed prices are one-way minimum fares and seat availability is limited. Popular routes and weekend departures are likely to sell out quickly.
- Minimum fares may not be available during peak periods such as public holidays and the year-end season.
- The STANDARD fare includes 15kg of checked baggage, but change and refund conditions follow the applicable fare rules.
- The promo code is app-only. Some flights may be excluded or ineligible for combination with other offers, so always confirm the total before payment.
- Sale terms and fares are subject to change or early termination without notice.
Summary
A one-way total fare from 12,530 yen including 15kg of checked baggage is an aggressive price point for the Japan-Korea market, and the app promo code can push it lower still. Anyone considering a Korea trip between autumn and the end of the year should act early. Full details and bookings are available at https://www.traicy.com/link/7C .
