Embarrassingly bad, but here goes (reservation was for two people, but all prices are per person):
PHL-MIA-CUN 35k AA (AAnytime Award)
CUN-MIA 17.5k AA
MIA-PHL 12.5k AA
So basically, 65k AA per person for a vacation in Cancun with a long stopover (for Shabbos) in MIA on the return. Brutal.
Booking made in March 2014.
