I jumped on this fare as well since I had a light travel year and needed some TPs, didn’t optimize it as much as you guys did: AMS-LHR-JFK-LAX-BOS-LHR-AMS, with both transcontinental flights upgraded to First, booked on AA stock but with BA flight numbers for extra avios. 640TP and 42K avios (as gold) for 1200 euro not bad!
