My wife, at the time an AS non-status Flyer, recently received her JL boarding pass for an AS award ticket and it showed “Sapphire” for her status.

I remember other threads in past years after the OW integration where OWE flyers only saw Sapphire on their boarding passes.

I don’t know how OW airlines communicate flyer status - do their programs feed into a central database and airlines then look up status from there? I imagine it can’t really be part of the ticket/reservation as status changes frequently.
