(correct me if I am wrong)
Other terms I think may come in handy when it comes to priority in standing by,
In Transit -- Refers to a passenger making a connection where both coupons came out of the same ticket book.
Local Boarding -- Refers to a passenger beginning his trip (includes beginning his return trip) or resuming travel after a stopover. Includes passengers making a connection when the connecting flight is part of a separately booked journey.
Inbound -- May describe the first flight when talking about one flight connecting with another.
If you check in timely and are about to be denied a seat such as when standing by or being bumped (or if the agent is not busy) the agent or a supervisor or manager must show you the boarding priorities in writing on request.
