Letters don't matter. You can have a light Y or full flex K, whatever. It's just an ancillary.
Flex gets SkyPrio. Also Gold and other SkyTeam Elite Plus.
Silver doesn't get SkyPriority and neither does Classic Y.
FB Silver do get some preferential treatment in particular at hubs (priority checkin for example), but that's not Sky Priority and will not show up on BP.
