I don't know why any pilots are volunteering money to pay for CrewPass.

It will end up being in each airlines best interest to pay the CrewPass fee and write it off as an expense.

Pilots, in general have a pretty low BS tolerance level. As more and more pilots "opt-out" of the machine scan, the TSA pat down lines will get longer and longer and soon will start affecting the D-0 performance.

Like most things, airline managements react quicker to things that cost them lots of money or might cost them money (potential upcoming legislation), than things that are conveniences.

This issue is scaling exponentially due in large part to online media sites like The Drudge Report. It will reach critical mass sooner rather than later and will start costing the airlines money and what little good will is left from their paying customers.

It's one thing for a passenger to miss a flight because it took them forever to get through the security back log. It is quite another when entire flights or maybe every flight at a major airport is late because the crews are stuck in the backlog of security caused by crew AND passengers choosing to opt out. At that point the $50 per crewmember will look realllllyy cheap.
