Built for people who fly out of Thailand

SiamMiles exists because most rewards calculators are written for cards and programs that do not exist here.

Search for a points to miles calculator and you will find dozens of generic tools built around programs and card networks that do not operate in Thailand. None of them know what a K Point is, how Bangkok Bank's Thank You Rewards preferential tier works, or that GrabRewards just became GrabCoins. If you bank, spend, and fly from Thailand, that gap is exactly where value quietly gets lost. Points expire, get redeemed for a fraction of their potential worth, or never get transferred at all because nobody could find a clear answer.

SiamMiles focuses on exactly five programs that matter to people living in or flying from Thailand: K Bank K Point, Bangkok Bank Thank You Rewards, KTC FOREVER Points, TrueYou TruePoint, and GrabCoins. Each one has a confirmed, publicly documented transfer path into an airline mile program, whether that is Royal Orchid Plus, Asia Miles, AirAsia BIG Points, or KrisFlyer. We track the real ratios, minimums, and processing times for each.

What we do

• Maintain a calculator with two modes: a quick estimate for whether it is generally worth transferring, and an exact redemption mode for whether a specific flight is a good deal.
• Publish a side by side comparison table and a full guide explaining how each transfer path works, sourced from official program pages and independent travel rewards research.
• Flag when a program is in transition, most notably GrabCoins, whose airline transfer catalog changed substantially after the November to December 2025 GrabRewards rebrand.

What we do not do

• We are not a bank, airline, telco, or travel agency, and we do not process transfers, bookings, or payments.
• We do not guarantee that any rate shown here is currently live. Issuers change terms without notice, and we recommend confirming in the official app before every transfer.
• We are not affiliated with Kasikornbank, Bangkok Bank, KTC, True Digital Group, AirAsia, Grab, Thai Airways, Cathay Pacific, or Singapore Airlines.

Who runs this site

SiamMiles is operated by KF Technology Solutions (ABN 66 393 679 405), a registered Australian business. We built this tool because we bank, spend, and fly the same routes described here, and we keep every rate and ratio on this site sourced and dated for that reason.
