Overview

Netting as a ticketing concept is defined in IATA Recommended Practice 1721 / A4A XXXX. In the context of Enhanced and simplified distribution, netting is a process to determine if

• funds would be due from the payer in order to confirm a change to an existing order

• funds would be due to the payer as a result of confirming a change to an existing order

And that this confirmation would result in a single financial transaction one way or the other.

The following guidance relates to how RP1721 is applicable to Offer and Order scenarios where a ticket has been issued against an existing order item and the change would result in the issuance of a new ticket against the new items.

The netting process in this context is optional and depends on each airline’s individual business choice. At this time, netting is applicable only to flight scenarios and does not cover documents issued for non-flight services such as a baggage or seat with an attached EMD or a standalone EMD (see unsupported capabilities section).
