Jeju Air Opens Its September–October Sale on Japan–Korea Routes
Jeju Air is running a September–October Sale on its Japan–Korea network for three days only, from August 4 to August 6, 2026. One-way fares start at ¥12,930 all-in, making this a sharp window for anyone eyeing an autumn trip to Korea.
Crucially, the advertised fares are total prices that already include fuel surcharges and airport fees, so there is no large hidden add-on at checkout. The travel period runs from September 1 to October 24, 2026, covering the whole of Japan’s comfortable autumn travel season.

Lowest One-Way Fares to Busan

- Fukuoka – Busan: ¥14,930
- Tokyo/Narita – Busan: ¥15,270
- Sapporo/Chitose – Busan: ¥17,550
Routes That Include 15kg of Checked Baggage
Low-cost sale fares usually strip out baggage, but this promotion bundles 15kg of checked baggage into selected routes. If you plan on shopping in Korea, whether your route qualifies changes the real cost meaningfully.
- Seoul/Incheon: Tokyo/Narita, Nagoya/Chubu, Hiroshima, Matsuyama and Oita
- Busan: Tokyo/Narita and Osaka/Kansai
For every other route in the sale — Shizuoka, Kobe, Fukuoka, Okinawa/Naha, Sapporo/Chitose and so on — check the baggage terms on the booking screen before paying.
Things to Check Before You Book
- The sale lasts only three days. Fares revert after August 6, so decide early if your dates are set.
- Lowest fares are capacity-controlled. Friday-to-Sunday departures and dates around public holidays sell out first.
- Prices shown are one way. Budget roughly double for a round trip.
- Change and refund rules are stricter on sale fares than on standard tickets — read the conditions carefully.
- Seat selection, meals and extra baggage cost extra as a rule, and add-ons push the total up quickly.
Bottom Line
An all-in one-way fare from ¥12,930 is aggressive even by Japan–Korea standards. Regional departures such as Matsuyama, Hiroshima, Oita and Shizuoka are especially compelling, often working out cheaper than travelling to Haneda or Narita first. The September 1 – October 24 travel window also lands in the most walkable season for both Seoul and Busan. If your dates are firm, lock it in while the sale is live.
