That's how it always (doesn't) work with me......my wife and my son are on the same PNR as me, I have status but they don't, I'm shown as Sky Priority on my boarding pass but they're not on theirs. At Linate (for example) where the fast-track access is controlled by automatic gates, one is at the mercy of the SEA dipendente at the adjacent desk as to whether or not they let you through.
