Welcome the additonal feature to AA site. I am getting used to using the OW interactive map, the similarity of both maps noted.
Did notice some discrepancy between maps, when using "sort by distance" (upper right corner pane for search results). For example: From LAX. AA shows LAX-CPT is the longest; OW shows LAX-MEL. Also noted of course the "sort by distance" depends on where the flight makes the connection (s).
