Abstract: A method and system for presenting travel information in a way that facilitates identifying travel plans that satisfy objectives is provided. A travel information system collects travel information for the travel items on various observation dates including the current date and presents the travel information to a user in a way that facilitates travel planning and travel shopping. The travel information system stores the travel information in an observation store. To provide travel information that satisfies a search criterion, the travel information system retrieves the travel information that satisfies the search criterion either from flight information of the observation store or from current flight information provided in real time from a source of travel information. The flight information system provides the travel information in various formats to facilitate travel planning.

Abstract: A method and system is provided for making price-related predictions of items based on training a classifier using historical information including pricing information for the items and labels relating to the price-related information that are generated automatically from the historical information. A prediction system provides price-related predictions for airline tickets. The prediction system collects flight information for flights on a daily basis. The prediction system generates training data to train a classifier to make the price-related predictions using the flight information. After training the classifier, the prediction system then can make the price-related predictions for a trip.

Abstract: A method and system for protecting prices is provided. The price protection system increases consumer confidence when making purchases by reducing the risk associated with fluctuating prices. The price protection system receives a purchase specification from a consumer. Next, the price protection system determines the risk that the prices of items matching the purchase specification will change and reports a protected price to the consumer that represents the price that the price protection system will protect based on the determined risk for a protection period. Finally, the price protection system receives a request from the consumer to purchase protection of the protected price.

Abstract: A system for comparing terms to describe a transaction. The system receives, for a plurality of sellers of a time sensitive fixed capacity non-physical goods, a plurality of purchase information describing a transaction associated with each of the plurality of sellers, the purchase information comprising list price, taxes, and purchase terms. The system aggregates the plurality of purchase information in a database and standardizes a first purchase information and a second purchase information in response to a query for the first purchase information for a seller of non-physical goods. In addition, the system displays for substantially simultaneous viewing the standardized first purchase information with the second purchase information.
