My KLM-points are very valuable for me - for doing 1-way "business" trips "domestic Europe" combining with US$10-15 Ryanair cheap cheap ticket.
My *A points will mainly be used for First-class business and pleasure trips from Europe to Asia and from Europe to Brazil.
However, I have to find a creative way to "invoice" my company for all these trips (at published fare - 5% discount" :-)
