You can transfer Capital One Miles to airline loyalty programs like Qantas. Normally, you can transfer your Miles to Qantas at the rate of 1:1. But, now, there is a 20% transfer bonus when you transfer your Capital One Miles to Qantas Points through August 31, 2024.
With this offer, for every 1,000 Capital One miles you transfer to Quantas, you get 1200 Qantas Points compared to the usual 1000.
