I'm a relative newb to the world of status, but as a Silver I've had no trouble using the Skypriority queues for check-in and boarding at Frankfurt, CDG, BCN, and recently Montpellier. In fact, on my last flight from MPL my baggage was tagged with the Priority tag. At Frankfurt I had to remind the check-in agent that I was entitled to an extra checked bag but that's been the only hiccup so far.
The small touches are enough to keep me trying to hold onto Silver and fly AF......
