I had a CAL gate agent tell me I (my company-CAL Connection) wasn't authorized to jumpseat. Funny thing is on her desk at the gate, underneath some plexiglass, there was the jumpseat list with my companies name on it. I pointed it out to her and she said that she was told we couldn't, so we can't. I even showed her how to pull it up on her computer. Even with it in front of her on the computer, she still said we couldn't. Thankfully her supervisor came over and asked the problem. She asked who I was with, I told her, and she told the agent "sure he can jumpseat, the list is right here" - pointing to the list under the plexiglass. Thankfully I got on.
As much as I like CAL, it seems there are a lot of gate agents who are clueless as to their own policies.
Another example - Checking in at TPA for a positive space deadhead to our companies HQ in Plattsburgh, NY the ticket agent told me "Continental doesn't have any service to Plattsburgh" and promptly cancelled my listing and told me to move along (really!). I refused, called our crew scheduling and demanded to speak to a supervisor. Again, the supervisor straightened things out. I have a few other fun examples as I am sure we all do. But I'd think it would be a requirement for the job for the gate agents to actually know a little bit about the companyy they are working for (ie destinations).
