Excellent! Just the kind of comments I was hoping for. Thank you =)

I'm using money to buy the positioning flight so AMM or TLV actually might be even more value. Need to look into that. I have quite a lot of Avios and was planning on using them for few C flights to/from and within South America.

The route you suggested is otherwise good, but I'm not interested in Muscat. I think I would rather fly more in Asia or Australia. For example, fly HKG to Perth and then Darwin to SYD... or something like that. Whatever brings more miles to my BAEC account. I'm sure I will like the places no matter where I go (except Muscat....) =)
