In case anyone is interested, you can get all the way to the West Coast for $1,640ish round trip and can bounce around a bunch if you want to use it as a mileage / tier point run. INV-LHR-YYZ-JFK-SFO-LAX-JFK-LCY is $1,641 on 1/8/20 to 2/11/20 (I just picked some random dates). YYZ-JFK is economy but everything else is business. You get the new Club World Suite and the Baby Bus with this routing. I built the routing on ITA Matrix and then clicked through to the AA Hong Kong site using PowerTools.
