Stopover means a deliberate interruption of travel by the Passenger, agreed to in advance by the carrier, at a point between the place of departure and the place of destination.
....
For Domestic flights, a Stopover will also occur when a Passenger arrives at a point and fails to depart from such point on:
1. The first flight on which space is available; or
2. The flight that will provide for the Passenger’s earliest arrival at intermediate or junction transfer point(s) or destination point, via the carrier and class of service as shown on the Passenger’s Ticket; provided, however, that in no event will a Stopover occur when the Passenger departs from the intermediate/junction point on a flight shown in the carrier’s official general schedule as departing within four hours after arrival at such point.

5.Baggage will not be checked:
e. To an intermediate point unless the intermediate point to which the Baggage is to be checked is a permissible Stopover point at the fare paid (except if the Passenger is making a connection to the first available UA flight departing from such intermediate point and the connection exceeds four hours, the Passenger may reclaim his/her Baggage at such intermediate connecting point).
