Thanks for posting. It's possible to get this on all AA for a few euros more.
I'm US-based but am probably going across the pond twice before the middle of the year... if my plans were more solidified this would have saved a bunch of money and given me miles where I want them (Alaska). I managed to put together DUB-PHL-CLT-DEN-ORD-LHR-DUB, which nets 10,450 miles assuming the LHR-DUB segment on BA credits fine. 3.8 cpm.
