Just remembered that last year I did a LHR-ORD-SEA-LHR trip (my destination was SEA), which was cheaper than doing LHR-SEA-LHR, as for the fare calculation the BA LHR-ORD-LHR fare was used (including the AA flight ORD-SEA). Now as that undercuts the LHR-SEA-LHR fee with at least £100, why did this work? SEA was the 'stopover' on the way back from ORD....
BTW: booked on aa.com.
