All 5 Thai rewards programs, side by side
Transfer ratio, minimum transfer, destination airline, processing time, and key notes for every confirmed points to miles path in Thailand.
| Program | Transfer ratio | Minimum transfer | Destination airline(s) | Processing time | Notes |
|---|---|---|---|---|---|
| K Bank K Point | 4 K Points = 1 mile (4:1) | 20,000 K Points (→ 5,000 miles) | Royal Orchid Plus (Thai Airways)1 | About 5 business days (per Thai Airways; KBank does not publish its own figure) | Excludes KBank Titanium, business, and corporate cards. Earn rate: 25 THB spend equals 1 K Point. |
| Bangkok Bank Thank You Rewards | 3,000:1,000 (3:1) standard; 2,000:1,000 (2:1) Visa Infinite; 2,500:1,000 Platinum Leader | 3,000 points standard / 2,000 points preferential | Royal Orchid Plus (Thai Airways)2 | About 3 business days | Preferential 2:1 rate for Platinum Leader and Visa Infinite cardholders, who also earn points at double the standard rate. |
| KTC FOREVER Points | 4 FOREVER Points = 1 mile (4:1) | No fixed published minimum beyond the 4:1 unit | Asia Miles (Cathay Pacific), plus about 10 other airlines3 | Instant for Asia Miles in the KTC Mobile app (KTC's general transfer SLA for other programs is 1 to 10 business days) | Periodic bonus promotions have existed (for example, a past offer of 100 bonus Asia Miles per 5,000 points); check the KTC Mobile app for current offers. These are not part of the baseline rate. |
| TrueYou TruePoint | 1 TruePoint = 1 BIG Point (1:1) | 1,000 points | AirAsia BIG Points4 | Instant per AirAsia's own xchange rules, but we could not confirm this transfer partnership is still active in 2026 — verify availability in the TrueYou app before relying on it | Earn rate: 25 THB spend on True services equals 1 TruePoint. AirAsia BIG Points carry lower per point value than legacy carrier miles. |
| GrabCoins (formerly GrabRewards) | 13 GrabCoins = 1 mile (13:1), per Singapore Airlines | 650 GrabCoins (→ 50 miles) | KrisFlyer (Singapore Airlines)5 | Up to 15 business days per Singapore Airlines (still live post rebrand, but Grab Thailand's own app does not advertise this option, so confirm it appears for you before transferring) | Note: GrabRewards rebranded to GrabCoins (Nov to Dec 2025). Singapore Airlines still lists GrabCoins as a KrisFlyer earning partner, but Grab Thailand's own app centers on in app discounts (about 20 GrabCoins per 1 THB) and does not advertise mile transfers. Confirm the option appears in your Grab app's Rewards or Xchange section before relying on this figure.6 |
