THREE service problems on a single round trip J ticket SAN-Brazil.
1) MIA-CNF 1-2-1 767 was swapped with an ancient 2-2-2 767. 25K miles compensation
2) GRU-MIA flight delayed 90 minutes (crew/catering) caused misconnect/overnight in MIA. 20K miles
3) MIA-SAN flight delayed 2 hours due to crew rest. $200 voucher
So overall for a single very messed up J trip I got 45K miles and $200 voucher. Would have preferred no service problems, but I'm happy with the resulting compensation. AA service rep called me back about my third problem on this trip to personally apologize for the problems. Revenue ticket was $8.5k.
