As it stands, this invoice contains the value of the coupon to be paid, calculated by the participating 13P vat accounting and the corresponding compensation authorization code. The significant improvements foreseen by the invention are due to the fact that the invoice also contains the third indicator of the pavilion. Therefore, the invoice indicates whether an agreement has been reached through the messages previously exchanged: the UAC message, the SAC requirement message and the SAC reply message. If the e-ticket servers reach an agreement, the invoice contains the value of the 11P consolidator module. The 11P consolidator module refers to the E-Ticket Server PC 1P, the OK/KO Thirds display and the proportional value accepted or claimed by the participating carrier. It also sends the billing authorization code, the third flag indicator and the PVPC coupon to the participants` 13P billing PC through the 12P online links (steps 65 and 66). If an acceptance module of a given medium rejects the proportional value claimed by the other medium, the plate reporting that refusal can be sent in real time with the proportional value calculated or recalculated by that specified medium. If no paint value is available in the PC 3P coupon database, the E-Ticket Server System PC 1P sends a request for a standard regulation authorization code (step 44) to the e-Ticket Server VC1V system. Such a message, referred to below by an sACR message or billing authorization requirement message, is a standard industry message widely used in the aviation industry. This billing authorization requirement message allows the participating carrier to request a code that allows the sender to validate that the coupon can be used later, i.e.
the status of the coupon can be converted to final status. As explained above, “flight” is the end point of air travel. Therefore, the requested billing authorization code is a code by which the valid carrier issues the participating carrier an authorization for future billing. The absence of a proportional value at this stage can be explained by the fact that, for example, the participating airline has not previously calculated a proportional value. This may be the case where the participating airline has not obtained enough information to calculate a proportional value. Whenever an agreement is reached during the invention process, there is no need to analyze and review the detailed invoices. The invention thus shortens time and eliminates disputes that arise in time and cost. These United flight vouchers are distributed and billed in accordance with the special agreement between Great Lakes and the ticketing carrier or, in the absence of a special agreement with the height, in accordance with the ACH Procedure Manual. In addition, the agreement system allows, after a useful appearance, a synchronous exchange between the valid carrier and the participating carrier.
Therefore, the agreement process can be initiated at an early stage before the coupon is used. The solution is to support interline agreements concluded by an airline. Another attempt to simplify these procedures and reduce the time spent on ticket preparation and invoice verification was made through internal alliance agreements. As a reminder, at this stage, the existing method unilaterally determined the value of a coupon given by the validating carrier. Moreover, its value cannot be considered a deserving turnover as long as the service corresponding to the coupon is actually provided by the participating carrier. In particular, this coupon can be refunded, redeemed or changed before departure. Thus, ticket sales are initially accounted for in the form of “undeserved” revenue (as recorded as part of the validation) or “planned” revenues (as recorded by the parties involved).
