Air Busan is running the second round of its Busan Trip Coupon campaign on Takamatsu to Busan. Depending on what the round trip costs, JPY 2,000 to JPY 9,000 comes off at the payment screen for members, and both the campaign window and the travel window run from 1 August to 24 October 2026. Coupons go first come, first served and the campaign closes when the allocation is gone.

A round trip of JPY 11,000 pays JPY 2,000, so crossing the threshold by one yen takes JPY 3,999 off

Four coupons, four thresholds, and the gaps between them are not even.

Thresholds are the round-trip ticket values the airline publishes as coupon conditions. Effective rates are calculated at exactly the threshold. Checked on 2026-08-09; changes after that date are unverified.

Because the tiers are uneven, what you pay inverts around each threshold. A round trip of JPY 10,999 reaches only the JPY 5,000 coupon and leaves JPY 5,999 to pay; push it to JPY 11,000 and the JPY 9,000 coupon applies, leaving JPY 2,000. One yen more on the ticket, JPY 3,999 less at the till. The same inversion sits at JPY 4,000, where the threshold costs JPY 999 less than JPY 3,999 does, and at JPY 7,000, where it costs JPY 1,999 less than JPY 6,999. If seat selection or checked baggage is what carries you over a line, buying them lowers the total rather than raising it. The figures are the ticket values the airline uses to test the coupon, not the final bill — taxes and airport charges show up on the booking screen, and fares quoted on different bases need separating before any of it is comparable.

The flights run three days a week. BX1315 leaves Takamatsu at 19:35 on Tuesday, Friday and Sunday; BX1325 leaves Busan at 17:20. Monday, Wednesday, Thursday and Saturday departures do not exist. A 19:35 departure also means the first day is spent getting there, so a trip of a given length loses a night on the ground — and gains one on the hotel bill. If reaching Takamatsu means crossing Shikoku first, the local lines across the island belong in the same estimate. For the extra night at the far end, what a room in Busan costs is the figure that decides whether the coupon is worth the schedule.

More: this and T’way Air are quoting different things, so the face values do not line up

Among the Korea routes selling out of regional airports in the same weeks, T’way Air’s August t’sale publishes fares from Saga and elsewhere as all-in totals with the fuel surcharge and taxes already inside. Those numbers can be set against each other as printed. Air Busan’s coupon states how much comes off the fare instead, which is a different kind of number entirely. The only place the two meet is the final total on each booking screen, and reaching it on the Air Busan side means going as far as the payment method page, because that is where the coupon appears — or does not.
