Maybe go to Norway on 2 weeks of holiday on a Wideroe explorer ticket? That should get you a lot of legs for a cheap price!
Anyway, I find the easiest way is to fly Go/Plus on longhaul for a few weekends away to be the by far easiest way to qualify. However, if you have no time or desire to go to these places that is clearly not a useful option.
(I got over 230k base points last year from trying to avoid SAS on longhauls, unless they were dirt cheap or vastly more convenient - and SK/*A was not my no1 alliance)
