I second erwiol points. It is insane to earn merely 25% on so many classes, quite frequently even K is more expensive than Lufthansa W or V, which give full miles in M&M. I suggest that at least longhauls minimum should be 50%, and that is on the very very campaign prices. And redeeming - if you have to collect miles with those measely 25% rates and clock up EBG, then you can only get 1 economy return ticket in Europe (40k)! It is abnormal.
Recongnition is other thing. I think it would be lovely if in European flights, which SK prices on par with LH, BA, AF, KL or more expensive.. all of those provide at least basic service in economy. SK could at least adopt the bmi system, where Gold members get 1drink+1snack free when flying in P(unishment) class.
