Perhaps I haven't interpreted the OWE rules correctly but it seems that the following itinerary change for N.A. is not allowed:

originally on BA: MAD-LGW-GCM
then on AA: GCM-MIA-JFK-LAX (3 sectors)
then on CX: LAX-HKG-DPS

Proposed change on AA: GCM-MIA-GCM-MIA-JFK-LAX (5 sectors BUT 2 "international arrivals" @ MIA).

As the GCM-MIA-GCM-MIA segments are not "intercontinental", this would appear to be acceptable as far as I can tell. AA has advised *NO* based on the "Routing" part of the RTW rules and it would be greatly appreciated if other learned members of this forum could advise!
