I received an actual "enhancement" yesterday on a reissue by AA of a BA ticket-- ticketing an itinerary with 22 flight segments! Over the past month, only one of the 4 or 5 agents I talked with at both AA and BA seemed to know the rule about being able to end an Africa-originated ticket anywhere in Africa (I started in MRU but wanted to end in CPT). Yesterday when the ticket was finally reissued by AA, the agent had to check and confirm that it was possible. When I went to the airport to have the ticket reissued, I found that although the 20th segment does end in CPT, two more coupons were attached: CPT-JNB and JNB-MRU, both open dated but apparently valid flight coupons!
