THAI Airways is offering eligible KTC cardholders THB 2,000 off each qualifying round-trip ticket from Bangkok to Korea. Enter promo code KTCKTO2 during booking and pay with the eligible card. The booking window runs from 1 August to 10 December 2026 for travel from 1 August 2026 to 31 March 2027.
The benefit is limited to 250 promotional codes across the campaign and reservations must be made at least 72 hours before departure. It applies to adult round-trip tickets in Royal Silk or Economy on eligible Bangkok-origin flights. Taxes, surcharges, fees and travel insurance remain payable, so compare the final checkout total rather than the airfare reduction alone.
Search The Fare
Start on the THAI booking page, choose Bangkok as the origin and an eligible Korean destination, then enter KTCKTO2 before searching. Compare the promotional result with ordinary fares for the same flights. Cabin, date and inventory restrictions can mean the code is unavailable even inside the published period.
Check The Clock
Book no later than 10 December 2026 and at least 72 hours before departure. The travel period continues to 31 March 2027, but a later journey still needs to be ticketed inside the booking window. Limited code inventory can finish before the calendar deadline.
Price The Whole Trip
The THB 2,000 reduction applies to airfare, not government taxes, fuel or carrier surcharges, service fees or insurance. Review baggage, seat, change and refund conditions before paying. A slightly higher flexible fare can be better value than a restricted promotional ticket when plans are uncertain.
Use The Right Card
Pay with an eligible KTC credit card and keep the booking page, e-ticket receipt and card transaction record. If the code does not reduce the fare, do not complete payment on the assumption that it will be adjusted later. Recheck the route, passenger type and fare conditions first.
Plan Korea Entry
The ticket offer does not change passport, visa, entry or transit requirements. Check current rules for every traveller and connection before buying a restrictive fare. Allow enough passport validity and use the name exactly as it appears on the travel document.
