OT: When using the KF or SK booking engines, where (in the H.ll) do you find the actual booking class letter? When not crediting to EB, that is the crucial detail.
With SK: At the bottom of the right-most column of stuff, you should have a blue text "Show EuroBonus points". If you click that link, do you get some greyish text showing booking classes below "EuroBonus points earnings"?
