Well, now that's another type of connection. Basically, if you book anything through AA.com (US-based) on another carrier it's going to poll the availability and sell in SABRE, then transmit and receive information to/from the other carrier to confirm and then ticket the reservation. So in that case you'd have a SABRE locator for the ENTIRE journey, as well as an Amadeus locator for the BA flight (with the AA flight data added in the Amadeus locator for informational purposes only).
That's the basic, basic explanation. I use the free version of Tripit to track everything and it does a great job for that purpose.
