Open Segment

The Open Segment command is used if a client wishes to purchase a journey but does not wish to reserve a specific flight or date. This is most commonly used where a client requires a return ticket but wants to leave the return open dated. An Amadeus PNR cannot be composed purely of open segments. If the first segment in the PNR is an open segment it must include a date.

The command identifier for Open Segments is SO and is often referred to as "Sell Open".
