Abstract: Systems, methods, and computer program products for processing an online transaction to purchase an itinerary of products. In response to processing of the online transaction being halted, an OLTP system may queue a database record defining the itinerary and the forms of payment being used to purchase the products in the itinerary. In response to receiving a request to restart processing of the online transaction, the OLTP system may de-queue the database record, identify a set of products in the itinerary for which processing of the transaction has not been completed, and determine the status of each product in the set. Based on the status of each product, the OLTP system may determine a point at which processing should be restarted for the product, and a sequence in which the products should be processed.

Abstract: Systems, methods, and computer program products for processing an online transaction to purchase a set of products comprising an itinerary. In response to receiving a message indicating a form of payment being used to purchase the itinerary may be fraudulent, an OLTP system may identify product recovery rules with input parameters that are satisfied by a context of the online transaction. The OLTP system may apply the identified recovery rules to products determined to be critical to the itinerary. If the critical products are determined to be recoverable, the OLTP system may book the critical products to preserve the availability and pricing of the critical products while the form of payment is subjected to a fraud screening process. If the itinerary includes at least one critical product that is not recoverable, the OLTP system may determine that the questionable form of payment should be canceled.

Abstract: Systems, methods, and computer program products for processing an online transaction to purchase a set of products. An On-Line Transaction Processing (OLTP) system includes a plurality of databases, each maintaining rules for determining a merchant at a different analytical level. To process the online transaction, the OLTP system searches a global rules database for rules defining the merchant at a transaction level, and a product rules database for rules defining the merchant at a product level. The OLTP system applies the rules returned by each database to the products to determine a baseline merchant assignment for each product. The OLTP system may then search an override rules database for applicable merchant override rules, and applies the override rules to the products. When a final merchant has been determined for each product, the OLTP system updates a database record defining the set of products to indicate the merchant for each product.

Abstract: Methods, systems, and computer program products for handling electronic miscellaneous documents in response to voluntary modifications of services. A request, which includes first data for a passenger name record, is received for the airline reservation change. Second data for a first electronic miscellaneous document, which is linked to the first data for the passenger name record, is also received. A determination is made as to whether the first electronic miscellaneous document can be exchanged by applying at least one exchange eligibility rule to the first and second data. If the first electronic miscellaneous document can be exchanged, a fare for a service associated with the first electronic miscellaneous document is obtained from a pricing engine associated with the first electronic miscellaneous document. In response to receiving the fare for the service, the passenger name record is updated with a second electronic miscellaneous document including the fare for the service.

A request, which includes first data for a passenger name record, is received for a change to an airline reservation. Second data for an electronic miscellaneous document that is linked to the first data for the passenger name record is also received. A determination is made as to whether the electronic miscellaneous document can be exchanged by applying at least one exchange eligibility rule to the first data for the passenger name record and the second data for the electronic miscellaneous document. If the electronic miscellaneous document can be exchanged, an exchange of the electronic miscellaneous document is automatically processed.
