Abstract: A computer device is provided for determining remaining seats in a booking class having a maximum number of seats, which communicates with a user's computer device over a network to receive a user query, associated with travel parameters and including an amount of persons and at least two connect points, and obtains a schedule corresponding thereto. The schedule includes a cabin class with booking classes ranked by a criteria between a highest and a lowest booking class, the lowest booking class being a subset of the highest booking class. The computer device selects a least-cost-fare booking class from the ranked booking classes, which has an actual number of available seats at least equal to the amount of persons requesting seats and an applicable fare meeting the travel parameters, and provides an indicia thereof to the user, in direct response to the query. Associated systems and methods are also provided.

Abstract: The present invention provides methods for efficiently handling product availability queries. The present invention provides a local availability cache that is prepopulated with product availability listings from various product sources. Customer product availability queries are processed using the prepopulated availability cache, as opposed to independently querying each product source. The present invention also uses methods to manage the cache, such as by limiting the length of use data records stored for each start of use day to a maximum length of use and updating of data in the query using a function that updates data for start dates of use that occur sooner in time than for start dates of use that occur later in time. The present invention also uses functions to determine availability for length of use requests that exceed the maximum length of use stored in the cache by piecing together availability information for smaller lengths of use.

Abstract: A method and system for registering, storing and managing personal data for use over a network, and for allowing users to register for, link to and log onto third party Web sites. The invention queries a user for registration, authentication credentials information, such as user names, passwords, etc., for any type of application, and securely stores this data in a centralized user database. The invention prompts when registration/authentication is needed, and either manually with user intervention or automatically with user permission inputs stored data, or automatically creates the registration/authentication credential data for the user. The invention further monitors a user's network browsing, detects when registration/authentication is needed, and either manually with user intervention or automatically with user permission inputs stored data, or automatically creates the registration/authentication credential data for the user.
