Confirm award space on Asia Miles BEFORE you transfer

Transfers are final and cannot be reversed. Open Asia Miles's site in another tab, sign in, and load the exact flight you want at the points price you expect. Come back only when you're ready to redeem.

Minimum transfer: 3,000 Marriott Bonvoy points

You can't transfer less than 3,000, and transfers must be in increments of 1,000. Transfer in 60,000-point blocks to capture the 5,000-mile bonus (60K Bonvoy → 25K miles).

2–7 days, sometimes longer

Marriott Bonvoy transfers are processed manually and are the slowest among mainstream currencies. Plan for several days minimum. These are typical times, not guarantees — always confirm award space first because transfers can't be reversed.

Cancellation: cancellation has a fee

$120 cancellation fee (or 17,000 miles) — one of the most expensive in the industry.

Fee: ~$120Window: Anytime pre-departureTaxes: Refunded minus fee

Points expiration

Marriott Bonvoy: Bonvoy points expire after 24 months without any account activity. A single earn (including from a co-brand card swipe) or redemption resets the clock.
Asia Miles: Cathay Asia Miles use a flexible model: miles are valid for at least 18 months and can be extended up to 36 months total by earning more miles. Effectively a hybrid hard-and-soft clock.
