Jeju Air 48-Hour Limited Sale: Overview
Korean low-cost carrier Jeju Air is running a “48-Hour Limited Sale” on its Japan–Korea routes. The booking window is very short, from September 28 to 9:59 a.m. on September 30, so it closes on the morning this article is published (September 30). The travel period is September 28 to October 31, making it worth a look if you are planning a trip to Korea on an October weekend or holiday.
The sale covers 10 routes to and from Seoul/Incheon and 4 routes to and from Busan. The lowest one-way fare is ¥13,230 on the Matsuyama–Seoul/Incheon route, and all listed fares are total prices including fuel surcharges, airport fees and other charges.
Sale at a Glance

- Travel period: September 28 – October 31, 2026
- Routes: Japan–Korea (10 Seoul/Incheon routes, 4 Busan routes)

STANDARD vs. BASIC Fares
Except for departures from Nagoya/Chubu, the sale offers STANDARD fares. These include 15 kg of checked baggage, making them a good fit if you want to check a suitcase or expect to come home with extra shopping.
Departures from Nagoya/Chubu also come with a BASIC fare that excludes checked baggage. The BASIC fare from Nagoya/Chubu to Seoul/Incheon starts at ¥14,080 one way, ¥400 below the lowest STANDARD fare on the Seoul/Incheon–Nagoya/Chubu route (¥14,480). For a short trip with carry-on bags only, BASIC can save you more, but if your luggage is likely to grow on the way back, factor in the cost of adding checked baggage before choosing.
Lowest One-Way Fares: Seoul/Incheon Routes (STANDARD)
The Seoul/Incheon routes on sale connect 10 airports in Japan, ranging from regional airports in Shikoku, Kyushu and the Chugoku region to Chubu, Kansai and Hokkaido.
- Matsuyama – Seoul/Incheon: ¥13,230
- Kagoshima – Seoul/Incheon: ¥13,430
- Oita – Seoul/Incheon: ¥14,230
- Nagoya/Chubu – Seoul/Incheon: ¥14,480
- Hiroshima – Seoul/Incheon: ¥14,600

- Kobe – Seoul/Incheon: ¥17,040
- Shizuoka – Seoul/Incheon: ¥17,250
- Sapporo/Chitose – Seoul/Incheon: ¥18,150
The cheapest are Matsuyama at ¥13,230 and Kagoshima at ¥13,430, with regional airport routes offering particularly good value. Note that Tokyo/Narita–Seoul/Incheon does not appear in the announced fare list, so travelers from the Tokyo area may want to consider the Busan route instead.
Lowest One-Way Fares: Busan Routes (STANDARD)
Four Busan routes are included in the sale, including one from Tokyo/Narita.
- Fukuoka – Busan: ¥14,530
- Tokyo/Narita – Busan: ¥14,770
- Osaka/Kansai – Busan: ¥15,770
- Sapporo/Chitose – Busan: ¥18,150
Fukuoka, Osaka/Kansai and Sapporo/Chitose have both Seoul/Incheon and Busan routes on sale, at the same lowest fare for each airport. You can choose between Seoul and Busan depending on what you want from your trip.
Who Should Book
Travelers living near regional airports
Many routes from regional airports such as Matsuyama, Kagoshima, Oita, Hiroshima, Shizuoka and Kobe are included. Flying to Korea from your nearest airport saves the time and cost of getting to a major city airport.
Travelers who want to visit both Seoul and Busan in one trip
Because fares are set on a one-way basis, it is easy to plan different routes for the outbound and return legs. For example, you could fly Fukuoka–Seoul/Incheon on the way out and Busan–Fukuoka on the way back to see both cities in a single trip. Travel within Korea costs extra, so compare the total cost.
Things to Check Before Booking
- Sale ends 9:59 a.m. September 30: Sale fares cannot be booked after the deadline, so act quickly if you are interested.
