What personal data is on the boarding pass that isn't needed for reimbursement, such as your name, and that matters after the trip (the PNR doesn't nor does the ticket number as even if a credit is attached to it, the funds would be nontransferrable)? I see only the last four digits of my FF number, PreCheck, my elite tier, and the fact that I preordered a meal (indicated as special meal requested, so not accurate). I guess it could become sensitive if someone had requested disability accommodations, but surely the employer would already know that.
