Due to a request for the "Allow strip change" to be more specific, the "Allow strip change" for "Father" destinations is now per the strip booked.
Until now it was per the "Father" destination of the flight and if the father destination allowed a strip change then the system would allow it.
From now, the strip change feature in the PNR will only be available if the specific destination is marked with "Allow strip change".
Please update your "Destination setup" and mark the destinations themselves with "Allow strip change" according to your needs.
The above only relates to HUB flights and does not relate to From-To, From-Via-To and Multi-leg flights.
