Forgive me if this question has been asked before... I'm a newbie to redemption and looking for some advice from thou who art experienced in such matters.

I have relocated from the UK to Asia earlier in the year and will be flying home early in 2005 for my annual leave. During my time in the UK, I have racked quite some BA miles flying around Europe. Sadly I only managed to attain Sapphire status in the process...

Now I'm looking to buy the best-value Y ticket on CX for HKG-AMS and upgrade to J using my BA miles. Any advice on how to go about this would be greatly appreciated!
