Thanks allset2travel - I had heard the same about the CX hence the question.

dvs7310 - QR would cost around 50k additional Avios so not a huge amount, but I'm not Avios rich so it represents a significant portion of my balance. If I choose CX then I plan to convert Amex points to Asia Miles but as they're both 1:1 conversions. What do you mean about being eligible to enter Qatar? Are there strict restrictions? I'm a British passport holder so I had just assumed that I wouldn't have any issues.

My first preference is to use Virgin Points to book ANA but I'm very pessimistic about my chances of being able to do that!
