The Offer
KTC Mastercard users planning flights or hotels should check the current Trip.com campaign before booking. The promotion runs from 16 March to 31 December 2026, with travel dates extending from 16 March 2026 to 31 December 2027. It combines two types of value: Trip.com discount codes for flight and hotel bookings, and a KTC FOREVER points cashback route that can return 13% cashback when the redemption rules are followed.
The campaign is most useful for readers booking medium-to-large travel purchases. The bigger codes require higher spend, so the deal is stronger for family trips, international flights, multi-night hotels, premium rooms or combined travel planning than for a cheap one-way domestic flight.
What It Includes
For monthly flight bookings, KTC lists five thresholds: THB 400 off from THB 8,000 with code KTCMC26F1, THB 750 off from THB 15,000 with KTCMC26F2, THB 1,250 off from THB 25,000 with KTCMC26F3, THB 2,000 off from THB 40,000 with KTCMC26F4, and THB 3,000 off from THB 60,000 with KTCMC26F5.
For monthly hotel bookings, KTC lists THB 480 off from THB 8,000 with KTCMC26H1, THB 900 off from THB 16,000 with KTCMC26H2, and THB 2,500 off from THB 30,000 with KTCMC26H3. The hotel thresholds are easier to reach for a few nights in Bangkok, Phuket, Chiang Mai, Singapore, Tokyo or Europe, depending on the traveller's itinerary.
KTC also mentions Double Day promotions on 7.7, 9.9 and 11.11 with separate codes. These are worth checking for readers who can wait, but they should not delay a good fare if flight prices are rising.
How To Use It
Start from the KTC promotion page and click through to the Trip.com KTC Mastercard code page. Choose whether you are booking a flight or hotel, then match the booking value to the correct code. Enter the code at Trip.com checkout and confirm the discount is visible before payment. Pay with an eligible KTC Mastercard.
For the 13% cashback element, follow the KTC travel cashback registration instructions. KTC says the cashback applies when spending at Trip.com and redeeming KTC FOREVER points in the amount equivalent to the payment per transaction. This is not automatic in the same way as a checkout code. Readers should register correctly, keep confirmation and understand how many points they are using.
Who This Deal Suits
This is best for readers who already compare online travel agencies and are comfortable using discount codes. It is also useful for Thai residents, expats and frequent regional travellers who hold a KTC Mastercard and have enough KTC FOREVER points to make the cashback meaningful. A THB 2,500 hotel discount or THB 3,000 flight discount can be material when booking a family trip or long-haul fare.
It may not suit travellers who need complex airline ticket support, flexible fare rules, multi-city itineraries or hotel elite benefits. Booking through an online travel agency can sometimes make changes more complicated than booking direct. Readers should compare the final fare, baggage, cancellation rules, loyalty benefits and support channel before paying.
Fine Print To Check
Check the minimum spend before applying each code. Make sure the discount applies to the booking type you are using; a flight code will not necessarily work on a hotel and vice versa. Confirm whether taxes, fees, insurance, add-ons or local-pay hotel rates count toward the threshold. If using points cashback, check KTC's same-day registration and redemption rules before the transaction rather than afterwards.
