Thanks c-w-s, I am eyeing and ex-EU (likely ARN) - DOH - SIN return trip - so will get 560 points. But that means only 2 eligible flights. Any ideas how to add extra stops to include 4 eligible flights?
I looked at LON - HEL - ARN but connections are quite poor (and prices are very expensive too) so have thought of doing the eligible flights at the very end on a different day.
