CAT 17 - Higher Intermediate Point (HIPS), Fare Component.
It is assumed that the Higher Intermediate Point Rule applies. This category is used to negate that assumption when stopovers or connections are made at specified geographic locations. It is also used to indicate when travel via a Higher Intermediate Point (HIP) is prohibited. When this category is not present, the Higher Intermediate Point Rule applies.
Assumption: This category is not automatically processed; it allows carriers to indicate in free flow text any carrier Fare Construction Rules. This category is used to express exceptions to these principles, which are at the fare rule level.
