Abstract: An apparatus includes a cache and a hardware processor. The cache stores first and second seat maps for a first flight leg and a second flight leg, respectively. The apparatus determines a flight segment from a first location and a second location included in a request from a user. The flight segment includes the first flight leg and the second flight leg. The first and second seat maps are retrieved from the cache. The apparatus communicates the flight segment and the first and second seat maps to the user. The user selects the flight segment. The apparatus obtains updated first and second seat maps from one or more airline computer reservations systems (CRS) and updates the cache. The updated seat maps are presented to the user. Seat selections from each seat map are received from the user. The apparatus reserves the seat selections in the respective CRS(s).

Abstract: A system of rendering content according to availability data for at least one item includes a server to receive a content request from a user and, in response, to retrieve requested content. A rendering engine coupled to the server identifies at least one rule associated with the content and concerning the item. A rules engine coupled to the rendering engine generates at least one availability request corresponding to the rule and concerning the item. The rules engine receives the availability data for the item, retrieves additional content according to the availability data for the item, the additional content selected from among one or more stored content elements that concern the item, and communicates the additional content to the rendering engine for incorporation into the requested content. The rendering engine renders the requested content, including the additional content concerning the item.
