JAL seems like another interesting option, indeed, but I'm not sure about the JL flight requirement. It might work or then not. Generally, my problem is that I don't quite know whether my travel pattern will remain as it is for very long, as it's quite possible that I move to the other side of the world in a couple of years (and possibly to a middle-of-nowhere place where the choice of airlines can be very limited). BA is relatively safe as they do fly to all continents; and I'd probably visit home every now and then, so AY flights would be an option always, but I now realise that the programme sucks - I wonder how it manages to attract members at all.

I had a closer look at Malev, and the attractive part of Duna Club is that after reaching Gold, you get 50% tier bonus that counts towards status, so retaining the status (80,000 points required) should be rather easy. The earnings also seem pretty generous compared to most other OW programmes. However, the redemption levels look horrendous! If I read the table right, inter-continental return in business would cost some 240,000 points or more And of course with their fleet of 2 B767s the worthwile upgrade awards are next to none.

Here are some links to their programme pages, if anyone has any further insight on this option:
