Jin Air Launches Coupon Promotion for Korea Routes
South Korean low-cost carrier Jin Air is running a promotion on routes to South Korea from September 1 to September 15, 2026. During the period, the airline is distributing coupons offering up to 5,000 yen off round-trip fares, making autumn and year-end travel to Korea more affordable.
South Korea remains one of the most popular short-haul destinations from Japan, reachable in just two to three hours each way. With the summer heat easing from September and the autumn foliage season arriving between October and November, this is a well-timed offer for anyone considering a trip to Seoul or Busan.
Promotion Details
- Coupon distribution period: September 1–15, 2026
- Eligible routes: Japan to South Korea
- Discount: Up to 5,000 yen off round-trip fares
- Travel period: September 1 to December 23, 2026 (certain dates excluded)
Discount Amount Depends on Payment Method
One key point to note is that the discount varies depending on the credit card used.
- JCB card payment: 5,000 yen off
- All other payment methods: 3,000 yen off
The 2,000 yen gap is significant. If you hold a JCB card, paying with it for this booking is clearly the better choice. When booking for several people at once, the difference multiplies, so it is worth confirming your payment method before checkout.
Free Checked Baggage Up to 20 kg on Return Flights with JCB Card
Jin Air is also offering a separate perk: present a JCB card and receive up to 20 kg of free checked baggage on return flights departing from South Korea. This campaign runs until March 31, 2027, far longer than the coupon window, so it remains usable well after the promotion ends.
Checked baggage is typically a paid add-on with low-cost carriers, and Korean routes often charge several thousand yen each way. Since travelers frequently return from Korea loaded with cosmetics, snacks, and K-pop merchandise, free return baggage is a meaningful benefit. A practical approach is to travel out with carry-on only and use the 20 kg allowance on the way home.
Points to Note
- The travel period runs from September 1 to December 23, 2026, but certain peak dates such as the year-end holidays are excluded. Always check eligible dates before booking.
- Coupons may be limited in number and the offer may end once the allocation is exhausted.
- Eligible fare types and seat availability are limited, so some flights may not qualify.
- To use the baggage benefit, you must present a physical JCB card at the check-in counter. Check the official site for conditions such as name matching.
- Airport fees, fuel surcharges, and other taxes are charged separately from the fare.
Book Early
With the coupon window lasting only about two weeks, popular routes and dates are expected to sell out first. If you are planning a Korea trip during the October–December foliage or Christmas season, booking early is the smart move.
