Thanks for posting these. There's something for everybody on that list! The only trouble is, I find it hard to get organized so far in advance.
One must never forget, these are not refundable in any way. So, two tickets to Hong Kong (for example), something vital comes up, or you get sick, and that's 140,000 miles down the toilet. That's why I almost prefer to pay the normal miles price! Just a point of view for context.
