Update: another pilot (from my own company) did come along, knew the deal and left to go catch his backup plan. The agent had the CA check his FOM, and of course, I'm good to go. Then the Agent can't work the system well enough to get it to verify me in CASS and despite the Captains assurances, the agent denied me boarding; so I run for the backup plan where my company Captain already has the one jump....waiting on the next try...
I'm posting this as a warning as much as a rant. You can cruise along for months without a problem; then you have a day like today: brought to you by weather combined with incompetence and prejudice.
