The subject matter of this specification can be embodied in, among other things, a computer-implemented process for providing a travel-related offer for a travel passenger that includes receiving a request for a travel reservation system to initiate a travel reservation for a passenger. The travel reservation system may include passenger name records (PNRs) that each correspond to a passenger and may store reservation information for the passenger. The process may also include transmitting a passenger identifier to a customer feedback module, which may include customer profiles with data related to passengers' satisfaction with past service. The customer feedback module may be used to identify a customer profile associated with the passenger identifier and generate a travel-related offer based on the data related to the passenger's satisfaction with the past service provided to the passenger. The travel-related offer may be presented via an interface.
