The last few times I have traveled by air, I have shown my CCW license for my photo ID, to TSA. It always requires a supervisor to say it is OK.
When I voted, they refused my CCW as a valid means of ID. The county Election Board Secretary has now sent directives to all poll workers to accept CCWs.
Go figure.

I’ve used my CCW card at PBI and BWI. Nobody so much as batted an eye.
