KTC cardmembers can receive THB1,000 off an eligible THAI Airways round-trip ticket from Bangkok to Singapore by booking through the campaign route and entering code KTCSG. The ticketing window runs through 31 December 2026, while eligible departures can take place through 31 March 2027. The benefit applies to Economy and Royal Silk round trips under the published fare conditions.
This is a per-passenger airfare discount, not a deduction from the entire checkout total. Taxes, fuel surcharges, ticketing fees, insurance and other add-ons remain outside the discount. The KTC card used for payment must belong to one of the travellers, who may need to present it with identification at check-in. Children and infants are excluded.
Offer at a Glance
- The fare reduction is THB1,000 per eligible passenger.
- Route: round trip from Bangkok to Singapore.
- Code: KTCSG through the campaign booking page.
- Ticket by: 31 December 2026; travel by: 31 March 2027.

How to Use the Offer
Open the dedicated campaign booking page rather than starting in the THAI mobile app, because the published terms exclude app bookings. Search the exact dates and passenger count, select an eligible round trip and enter KTCSG before payment. Confirm that the fare line falls by THB1,000 for each eligible adult. Compare the final amount, including taxes and baggage, with the ordinary public fare for the same flights.
Read the fare conditions before paying. Change, cancellation and no-show fees depend on the selected fare family, and the ticket must be charged in full for any later date change under the campaign terms. Use the eligible KTC card belonging to a traveller, save the booking confirmation and keep the card available for check-in. One discount code applies to one person.
Important Conditions
- The code is for an eligible round trip from Bangkok to Singapore.
- Children and infants do not receive the discount.
- Taxes, surcharges, ticketing fees and insurance are excluded.
- The booking must use the dedicated web route, not the THAI mobile app.
- Fares, seats and change conditions remain subject to the selected ticket rules.
Who This Suits
The offer suits an adult KTC cardmember who already plans a Bangkok-Singapore round trip before the travel deadline. It should be compared against the same flights without the code, because a different fare family or sale can change the final value.
Continue Planning
Continue with current Thailand deals, compare Thailand money guides, and keep Bangkok dining guides nearby for the rest of the trip.
