One should add: if the traveller is at least a Gold with BMI.

I'm just about to fly Swiss J intra-Europe and have checked the earnings (I'm also a BMI basic member). BMI gives either 2000 miles or 2x the actual miles flown, depending if the flight is above or below 600 miles in distance. In my case it's less than that, I think. Thus nothing too generous here.

SK gives how much - 1200? - points? LH gives 2000 miles + 25% FTL bonus = 2500 miles. No questions left where to credit.
