There must be a bunch of holes in AA's network now that this AA/B6 alliance is falling apart.

As an example, AFAIK, there is no nonstop flights at all from MCO to LGA, JFK, or EWR on AA, and there were nonstops to all 3 from B6.

Requiring a connection from MCO (the largest tourist destination on the east coast) from NYC (the largest city on the east coast) on one of the largest airlines in the world is absolutely bonkers.
