Question about Non-Rev flights... when you get into the site, and click on the empty seat button, it brings up a window that has the booked seats, authorized, and capacity.

The capacity is like 3 seats more than the authorized. What does this mean? I was thinking that it might be for jump seats?

Realistically, lets say there are 5 coach seats available. 6 people are listed under non-revs. 3 employees 3 buddy passes. Will they all get on because the "capacity" is higher and 1 of the employees can take the jump seat freeing up a coach seat for the buddy pass person?
