Jeju Air (7C) is running a 48-hour flash sale on its Japan–Korea routes. One-way fares start at 11,530 yen all-in on the Seoul/Incheon–Matsuyama route. Every fare listed is an all-inclusive total that already covers fuel surcharges and airport fees, so there are no surprise add-ons at checkout.
Sale Overview
- Promotion: 48-Hour Flash Sale
- Booking window: July 28 – July 30, 2026 (48 hours only)
- Travel period: July 28 – October 24, 2026
- Routes: Japan to Korea (Seoul/Incheon and Busan)
- Pricing: Total fare including fuel surcharge and airport charges
The booking window lasts just 48 hours, but the travel period stretches from late summer all the way into late October — ideal for anyone planning a trip around Japan’s autumn long weekends.
Seoul/Incheon Routes: Lowest One-Way Fares
Lowest one-way fares (all-in) to and from Seoul/Incheon:
- Matsuyama: 11,530 yen
- Hiroshima: 13,100 yen
- Shizuoka: 13,250 yen
- Osaka/Kansai: 13,570 yen
- Oita: 13,630 yen
- Fukuoka: 13,930 yen
- Nagoya/Chubu: 14,580 yen
- Tokyo/Narita: 14,770 yen
- Kobe: 14,840 yen
- Okinawa/Naha: 15,930 yen
- Sapporo/Chitose: 17,550 yen
Matsuyama is the cheapest at 11,530 yen. Regional departure points are generally the best value, though even Tokyo/Narita at 14,770 yen is a strong price for an all-inclusive international fare.
Busan Routes: Lowest One-Way Fares
Lowest one-way fares (all-in) to and from Busan:
- Osaka/Kansai: 13,570 yen
- Fukuoka: 13,930 yen
- Tokyo/Narita: 14,770 yen
- Sapporo/Chitose: 17,550 yen
Fewer routes are on offer to Busan, but Osaka/Kansai matches the Seoul fare at 13,570 yen. If you want beaches at Haeundae and the food stalls of Gukje Market rather than another Seoul trip, Busan is worth a look.
Routes That Include 15 kg of Checked Baggage
On the following routes, 15 kg of checked baggage is included in the fare — a meaningful extra given that low-cost carriers usually charge separately:
- Tokyo/Narita, Nagoya/Chubu, Hiroshima, Matsuyama and Oita to Seoul/Incheon
- Tokyo/Narita and Osaka/Kansai to Busan
Other routes (Shizuoka, Kobe, Fukuoka, Okinawa/Naha, Sapporo/Chitose and so on) may have different baggage terms, so check the allowance shown during booking before you pay.
Things to Check Before Booking
- All prices are lowest one-way fares with limited seat availability. Popular dates and departure times can sell out quickly.
- Sales close after 48 hours, on July 30. If your dates are already set, book early.
- The travel period runs July 28 to October 24. Flights outside that window are not covered by the sale.
- Sale fares typically carry restrictions on changes and refunds. Read the fare rules before confirming.
- Fuel surcharges and airport fees are included, but seat selection, meals and extra baggage remain optional paid add-ons.
- Confirm the latest entry requirements for Korea, including electronic travel authorization (K-ETA), before you travel.
Bottom Line
Jeju Air’s 48-hour flash sale stands out for two reasons: transparent all-in pricing from 11,530 yen, and 15 kg of checked baggage included on selected routes. With travel valid through October 24, it works for both a quick end-of-summer escape and an autumn holiday trip.
With only 48 hours on the clock, check availability on your preferred route sooner rather than later.
