Section IV - Fares and Routings

Rule 180AS - Stopovers

1. A stopover, as used herein, will occur when a passenger arrives at an intermediate or junction transfer point and fails to depart from the intermediate or junction transfer 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 shown on the passenger's ticket. Provided, however, that in no event will a stopover occur when the passenger departs from the intermediate or junction transfer point on a flight shown in AS's official general schedules and/or serving patterns as departing within four hours after his/her arrival at such point.
2. Except as otherwise provided, stopovers will be permitted only upon payment of the combination of applicable fares on transportation solely within the United States.

Routings

1. Each fare applies only to transportation via the routings specified in connection with such fares. Any local routing in connection with a fare applicable to transportation over the lines of any one carrier between any two points shall be included in any routing in connection with:
   1. Any published joint fare which includes transportation over the lines of such carrier between such points, unless expressly excluded from the joint fare routing or routings, or
   2. Any through fare constructed by combining a local fare with a joint fare. In such instances, the local routing of any one carrier shall apply to its entire portion of the through routing, whether or not the passenger travels via the point over which the fare is combined.
2. When more than one local fare applies for the portion of passage via a carrier participating in a joint fare, the joint fare shall apply only via the routings specified in connection with the lowest local fare.
