Additional parameters for flight booking systems are transferred together with the main parameters in the authorization request and can also be transferred in requests for confirmation, bill creation or payment via silentpay and tokenpay web services, depending on which of these requests the merchant uses.

The ticket number is sent within the confirmation request (charge service). In both cases airline fields are transferred together with a request parameters.
