[QUOTE= AA “could” interline bags on separates to any carrier they have an agreement with, but in practice, they won’t. They’re not in the business of rewarding customers for combining noncombinable fares on a journey via separates.[/QUOTE]

Yeah, I can see that. In this case though, it's not like I'm shafting AA on anything. They'd still get a comparably priced ticket purchase from me to SVD or BGI either way. It's just easier if SVD wasn't sold out for my date because you can take ferries. From BGI need to fly though to the small islands. AA doesn't service them directly and has no partners in the region.

It was easier to get around down there before the demise of LIAT, when St. Lucia acted as more of a secondary local air hub.
