Nice work and thanks for sharing, I am collector of older and obscure AA fares. A few things from messing with this...
Lots of routings possible, I did CAI-AUH-LHR on EY, too bad it isnt an F fare! Tried LAX routings, must exceed MPM.
The $800 AA YQ can be sliced to $300 or so if you end-on-end an appropriate fare to mask the YQ calculation. These AA unreatricted fares have no restriction on EoE ticketing. LH is best avoided as it adds $175 YQ for that short flight.
