Abstract: Described is a system and method for matching a customer's offer for travel services with quotes from providers of those travel services in a way that allows the providers to negotiate preferential treatment. An online travel service exchanger receives an offer from a customer for travel services, such as airfare. The online travel service exchanger attempts to satisfy the customer's offer by retrieving from a global distribution system one or more quotes for the identified travel services. Rather than merely requesting quotes from randomly selected airlines, the online travel service exchanger first requests quotes from one preferred airline at a time in descending order of preference until the offer is satisfied. If no preferred airline satisfies the offer, the online travel service exchanger may request quotes from a group of non-preferred airlines. The online travel service exchanger then satisfies, if possible, the offer with one of the quotes from the non-preferred airlines.

Abstract: A facility for display multimedia artifacts is described. The facility displays a map of a three-dimensional space. The facility further displays a plurality of perspective icons, each in a particular position and orientation relative to the map. When a user selects a displayed perspective icon, the facility displays a media artifact captured from the position and orientation of the selected perspective icon in the three-dimensional space.
