Two or more air segments that do not contain the same number of seats are booked in the same
PNR.
A non-homogeneous condition can be created intentionally to accommodate passengers who do not wish to
share the entire itinerary. For example, a family may be booked to travel together on the same outbound
flight but decide to return on different flights. When the reservations are made for different return journeys,
the PNR enters a non-homogeneous condition.
The non-homogeneous condition is temporary and only exists until end of transaction.
At end of transaction, the system splits the original PNR and creates a separate PNR for each passenger or
party that shares the same itinerary. Record Locators of these PNR’s are displayed in the AXR (Associated
Crossed Reference) record at end of transaction. To retrieve AXR records from a PNR, type
RTAXR. You
may also view the AXR PNR’s merged together by using the
RV command from one of the PNR’s.
To make end of transaction possible each segment containing less seats than the number of name elements
in the PNR must include passenger association. Passenger association can be included in the segment sell
entry, or can be added to existing segments. e.g. 5/P1
