Yeah, this rule is quite annoying since there is no longer a OW carrier in Africa or South America. I'm sure it was written when both Comair (BA) and LA were both still in OW and hadn't taken into consideration that now we pretty much have to connect via DOH for most intra-Africa connections and connect via MIA or DFW for most intra-South America connections.

WB (Rwandair) has been rumored to join OW with QR's help for some time and would help tremendously for these tickets. Even AT is no use since Morocco is treated as Europe as well for xONEx routing. I also really hope we see another South American carrier at some point, but the big ones are all in alliances except LA which DL would never allow to re-join. G3 doesn't have much reach outside of Brazil and seems to be the only viable candidate. Currently to get from one point to another in either continent you have to do it as a surface segment on the xONEx and get your own ticket.
