Japan Airlines has two KTC booking routes for Bangkok departures. The sharper offer is up to 30 percent off selected Economy fares to Osaka, with booking required by 31 August 2026 and travel completed by 30 September. A broader Japan campaign runs through 31 October 2026 for travel as late as 31 March 2027, with smaller reductions.
The headline percentage applies to named booking classes and eligible flights, not every seat shown on the calendar. Taxes and carrier surcharges remain payable, inventory is capacity-controlled and the trip must follow the published operating and marketing rules. Compare the final return total against the normal JAL price before paying.
Osaka Window
For Bangkok to Osaka on JL728 and JL727, KTC lists 30 percent off Economy booking class Q and 20 percent off Business booking class X. Use code 26CITHKTCKIX for a round trip booked from 1 to 31 August 2026 and travelled from 1 August to 30 September 2026.
Wider Japan Offer
For eligible Japan itineraries, KTC lists 12 percent off Economy class Q and 8 percent off Business class X. Use code 26CITHKTCJP from 1 August to 31 October 2026 for travel from 1 August 2026 through 31 March 2027. The eligible itinerary and flight rules still need checking.
Price The Whole Trip
Search the exact dates through the campaign route, then compare baggage, changes, refunds, seat selection, taxes and airport access. A promotional booking class can be more restrictive than a higher fare. Osaka’s Kansai Airport is outside the city centre, so add the rail or bus transfer to the trip budget.
Enter The Code
Start from the linked campaign instructions, enter the correct code for the intended route and confirm that the discount appears before payment. Do not assume the card will trigger it automatically. Pay with an eligible KTC credit card and save the fare breakdown, e-ticket and campaign screen.
Treat Points Separately
The campaign also describes a 15 percent KTC FOREVER points cash-back route for qualifying transactions when enough points are redeemed and registration is completed on the transaction date. That is separate from the airfare reduction. Check excluded cards and decide whether spending the points is worthwhile for you.
Book
Review both fare tables and campaign codes. Enter passenger names exactly as shown in passports, confirm Japan entry requirements for each traveller and avoid non-refundable hotels until tickets are issued.
