SAS doesn't "pay" specifically for fast track security at MUC, FRA, or IAD but SAS EBG or premium passengers can use these facilities. It's a simple matter of decency and reciprocating.

Does Swiss really "pay" for fast track security at ARN? Flat fee, per premium passenger, or per passenger that uses the service?? Their check-in desk is 10 meters from the "charter gate" security, which only has a premium security for Norwegian. So Swiss premium passengers should walk 500 meters to the other end and then take the stupid detour through the tax free shop and then hike 500 meters back to the lounge area.
