Cathay Pacific allows members to purchase Asia Miles exclusively as a top-up when booking an award flight, provided they already possess at least 70% of the required miles. Miles must be purchased in 2,000-mile blocks, with a maximum of 30% of the total required miles allowed for purchase, making alternatives like credit card transfers generally more cost-effective.
