Once the interline agreement is in place, the Retailer and the Supplier will exchange information about their Products and Services via the Product Catalogue.
It is assumed that this initial exchange will occur before the actual shopping transaction and that, the Product Catalogue will contain information about the Products and Services that it is not included afterwards in the shopping request.
The Product Catalogue concept and requirements will be further developed by the Interline Group and hence have not been included and detailed in this release.
The services proposed by a Supplier to the Retailer (or Retailer to Seller) that are part of an Offer Item must be purchased and ordered together (as a whole). These services, provided by the Supplier, can be integrated by the Retailer in the Retailer Offer/Order Item proposed to the customer.
From an Order perspective the Service should be linked and correspond to one passenger.
The Service ID must be unique within the overall Order (not just Order Item, but the entire Order).
The Settlement value is at Service level.
It is assumed that the Supplier is able to provide the taxes for the provided Products and Services and the Retailer has the capability to compute the overall taxes for the entire journey. This will be further investigated by the Interline Group and IBSOPS.
The aim is to further increase this scope and include flight related services.
