Abstract: A user of a personal computing device may interact with a network-based travel service with respect to one or more travel items. The network-based travel service may monitor the users' interactions, determine user's travel interests, and provide relevant travel item provider devices information for generating user-specific offers. For example, anonymized user statistics, suggested terms for a user-specific offer, or estimated likelihood of acceptance may be provided to the travel item provider. The network-based travel service may receive and evaluate user-specific offers submitted by the travel item provider, cause presentation to corresponding users, and enable the users to accept, decline or propose modifications to the offers.
