Category 8 – Stopovers defines the conditions when a stopover(s) is permitted or required within the fare component or pricing unit and the applicable charges, carriers, and locations associated with those stopovers.
In order to validate this category it is mandatory to know the following:
When there is no data present for Category 8:
In the absence of Category 8 (no Category 8 Record 2 that resolves to the fare or no Category 8 Record 3 is applicable within the string) the system assumption is that stopovers are not permitted at any point on the fare component being validated. A stopover is defined as an interruption of travel greater than 4 hours for the ATPCO Domestic Fare Product data and greater than 24 hours for the ATPCO International Fare Product data.
When there is data present for Category 8:
When processing resolves to an applicable Category 8 Record 3 that permits/requires stopovers, stopovers may occur at any point on the fare component/pricing unit (depending upon the presence or absence of data in the MAX field (bytes 16-17) with no geographic or carrier restrictions unless otherwise specified. No charges will be assessed unless otherwise specified. Additionally, stopovers at embedded surface sectors are permitted provided both end points of the surface sector are permitted (i.e. based on Recurring Segment data); an embedded surface sector only counts as 1 stopover. A stopover is defined as an interruption of travel greater than 4 hours for the ATPCO Domestic Fare Product data and greater than 24 hours for the ATPCO International Fare Product data, unless otherwise specified in the Category 8 Time Fields (bytes 52-59).
Fare break points are never considered stopover points for the purposes of processing Category 8 data.
