(m) Nonstop transatlanticTravel on AA between DEL and ORD is permitted.
For travel ex South America/South West Pacific – when this service
is utilised a minimum of a 4 Continent Fare must be charged.
For travel ex North America/Asia – when this service is utilised a
minimum of a 3 continent fare must be charged.


That's bad news... the wording doesn't seem quite so clear to me:

Does "ex South America / SWP" mean "including" or "originating in"; and if it means "including," does it implicitly mean simply that "flying ORD>DEL" counts for an extra continent (Europe) but you don't get stopovers in the continent.

Is there a good logic for this, eg., it would make three-region RTW trips (SWP>HKG>JFK>ORD>DEL>HKG>SWP) too close a substitute for the higher fare round trip business class flights they offer?
