And if that's right, then given the back-tracking involved in PHL-LHR-HEL-ARN, there seems to be a good chance that this was an ex-ARN ticket that the OP intended to finish, with a final separately-booked positioning sector back to London.
If all had gone well, it seems that the itinerary should have been this:-
AA728 PHL-LHR 2040-0900
AY1332 LHR-HEL 1020-1515
AY813 HEL-ARN 1600-1600
BA781 ARN-LHR 1805-1950
Even if all of these connections had been protected, this would still have been an itinerary with little room for error. There certainly doesn't seem to have been much planned for the day other than flying. It's perhaps too easy to say, though, that the misconnect provided a watertight reason for skipping the "last sector" (something of which I am often glad when it happens at the end of my ex-EUs) as presumably there were 120 TPs at stake plus whatever would have been earned on the final sector by those on the cash tickets.
