I saw this posted on another forum and I had the same question: for redeeming flights between HKG and LHR, which airline / FFP do you prefer? Living in HK it's easy to get sucked into the Cathay / Asia Miles ecosystem, but flight redemptions (especially in the premium cabins) are notoriously difficult.
One option seems to be Virgin Atlantic; redemption rates appear to be slightly cheaper than Cathay.
For those who fly this route, what is your redemption strategy?
