It’s been a while since this was last offered.
Between 1 September and 30 September 2025, simply register via the form on the Asia Miles website and make a conversion from American Express or BNZ to earn 10% bonus Asia Miles. Bonus miles will be credited within 10 weeks of the conclusion of the promotion.
If you want to fly Business Class with Cathay almost the only option these days. They rarely release any availability to partner programmes.
Overall a good loyalty programme with a transparent award table. Miles also don’t expire if you have an actively used account (i.e. account activity at least every two years).
Are they any good? Have anyone used them before?
