[quote=rickair7777;118161]1) Yes, you have to see the captain to check in when jumpseating even with a seat in the cabin. Try not doing it, and you'll get thrown off most airlines.

Okay, so you're not saying that you have to actually see him (her) sign the paperwork, you just have to introduce yourself as a jumpseater. This, of course, is true. Because there are plenty of times that the agent will walk my paperwork down the jetway so the [preflighting] captain can sign it. I don't see him sign it, but he looks at my stuff and signs off on it. I, of course, stop in to introduce myself and ask where they would like me to be, or let them know where I am sitting.

It wouldn't make much sense to have this conversation:

Gate agent: "Excuse me sir, did you actually see the captain sign that slip?"

Jumpseater: "Well, no. The agent brought it down to the captain."

Gate agent: "Well, sir, you actually have to see the captain sign it. I'm afreaid you're out of here."
