Regular check-in: 0% but I suspect this is airport specific. BWI is in the running with EWR for unpleasant check-in staff. They cannot even crack a smile.
GS Check-in: 100% (no surprise)
Mainline: probably 100% in any cabin domestic or international
UX: probably 0% in any cabin. In fact, I cannot recall any time since the pandemic started having a UX FA recognize my status
Club: 100%
Polaris lounge: 100%
This has been really consistent for me.
