And by the way, the reason nobody offers a better way to view fare rules/routings is because the GDS' closely monitor "messages" sent to/from their system, and establish a ratio of messages to bookings. If you generate too much traffic/messages without making many bookings, you either get charged for the messages, or lose your contract to access the GDS.
For this reason, it just isn't economical to offer people the ability to perform high volume queries to the GDS, unless it's something which offers a more direct return for the company providing the service.
