First time in BA metal in ecomony and not really sure how to navigate it, appreciaet the help!
IMO no way I'd waste a SWU to go from Y to PE on BA on LHR-BOS.
Not only would you be on the hook for any additional BA carrier surcharges, you'd also have to pay the higher UK APD, and this would only get you to PE, on LHR-BOS no less, which is one of the shortest TATL flights out there.
If you want to upgrade the return I'd just call AA and see what the fare difference is to switch to the AA metal flight back and try to use a SWU on that. At least it would get you to J.
