Abstract: The invention is directed to a computer environment in which a management system for a transportation carrier, e.g., an airline carrier, generates a list of routings based on preference data for a customer. The preference data includes data that may be used to select a particular routing, e.g., ticket class, seat assignment, meal service, airline, type of aircraft, connection points, connection times, fare, and an extended travel window. The preference data may be entered via a network user interface and stored in a central database. One or more profiles may be stored for a customer, such as a business profile, personal profile, or trip specific profiles. In this manner, when a user submits a search request, the management system generates a list of routings that satisfy the customer preference data. Furthermore, the management system may provide increased performance by reducing the number of search requests submitted by a customer.
