Thats part of the bilateral agreements they usually sign. Airlines usually present the bill for performing a service to the agency that issued the ticket after performing the service. In the revenue world this is done over the IATA BSP clearing house and agencies can issue tickets because the BSP holds a bank guarantee to cover the amount of tickets they issue. In award tickets a similar tally is kept that is defined in the bilateral.
