The subject matter of this specification can be embodied in, among other things, a system that includes a user interface to receive an electronic status change for an airline flight and an airline reservation system to determine whether at least one ancillary travel service associated with the airline flight should be modified based on the received electronic status change. The system includes a messaging interface to electronically transmit a request to modify the at least one ancillary travel service based on the electronic status change if the determination is made to modify the at least one ancillary travel service. The messaging interface further electronically transmits payment information to the travel service provider for use in crediting or debiting a payment associated with the at least one modified ancillary travel service. The payment information is associated with a customer that reserved the at least one ancillary travel service.
