open jaw

1. A trip that is essentially of a round trip or circle trip nature except that the outward point of departure and the inward point of arrival, or vice versa, are not the same.

2. (Subcategory 101, US/CA fares) Turnaround Open Jaw = The outward point of arrival and the inward point of departure are different. At least one fare component must be priced using half of a round-trip fare. Origin Open Jaw = The outward point of departure and the inward point of arrival are different. At least one fare component must be priced using half of a round-trip fare. Single Open Jaw = Either the outward point of arrival and the inward point of departure are different, or the outward point of departure and the inward point of arrival are different. At least one fare component must be priced using half of a round-trip fare. Double Open Jaw = Both the outward point of arrival and the inward point of departure are different, and, the outward point of departure and the inward point of arrival are different. At least one fare component must be priced using half of a round-trip fare. Open Jaw = Any of the above. Open jaws can consist of two or more fare components unless otherwise restricted in Subcategory 101 Record 3. See also combinations.

3. (Subcategory 101, International fares) Using applicable half-round trip fares: Turnaround Open Jaw = The outward point of arrival and the inward point of departure are different. Origin Open Jaw = The outward point of departure and the inward point of arrival are different. Single Open Jaw = Either the outward point of arrival and the inward point of departure are different, or the outward point of departure and the inward point of arrival are different Double Open Jaw = Both the outward point of arrival and the inward point of departure are different, and the outward point of departure and the inward point of arrival are different Open Jaw = Any of the above. Open jaws can consist of two or more fare components unless otherwise restricted in Subcategory 101 Record 3.

2. (directional fares) All fare components that are selected in the direction of the passenger's travel.

overwater

Applies when crossing a water mass within Area 1. When validating overwater travel, processing will determine the endpoints of a sector (coupon). Both end points must be within Area 1. When one end point is within the continental United States/Canada and the other endpoint is outside continental United States/Canada, this is considered overwater travel. This definition applies specifically for sectors between the following points: Between Continental US/CA and Hawaii Between US/CA/Hawaii/Alaska and Puerto Rico/Virgin Islands Between Alaska and Hawaii.
