Linking
Links between Customers affect the way Customers are identified, accepted and updated. The primary purpose of linking is to ensure that Customers are seated together on a flight.
Linking takes place automatically in the following situations:
 Customers are booked in the same PNR.
 Customers are accepted together.
 Customers are members of the same baggage pool.
 An infant booking is created or added to a Customer.
Links can also be added, split and removed manually. Links between Customers and associated infants, EXST, and CBBG are created automatically. A link between a Customer and an infant cannot be removed. The link between Customer and CBBG can be removed, but it cannot be changed. The link between a Customer and EXST cannot be changed and can only be removed in case of disruption.
Once Customers are linked (automatically or manually), all the Customers included in the link appear in the Customer Product (CP) table whenever you identify one or more of them for acceptance or update.
Links are used by the seat server when assigning seats automatically during the Customer acceptance process. When you add links between Customers who have already published seats assignments. The system prompts you to include those Customers in seat shuffles so that more suitable seat assignments can be made.
Linking levels
Links can apply between Customers for all flights they have in common, or for specific flights. The same Customer can therefore have different links for different flights.
There are three levels of linking:
 Linking – The system automatically applies this link to customers who are booked in the same PNR or accepted together. You can add top-level links manually, if the Customers are not linked at this level.
A top level link can only be removed manually.
 Sub-linking – This link is applied when you add a link between Customers who have already linked at top level. Sub links are used to create a smaller collection of linked Customer within a larger group already linked. A sub-link can only be removed from Customers manually.
 Adjacency linking – This link level is applied when adding a link between Customers who are already sub-linked. Adjacency links are used to indicate that sub-linked Customers should sit next to each other. An adjacency link can only be removed manually for Customer acceptance before acceptance.
