Why not just find any random flight and upfare as appropriate to hit $723? You don't care about distance, so literally you could book the most expensive fare to LAX/SNA/ONT/DEN/etc and back and be done probably in a few hours. If you want something a bit nicer (in terms of a ride), you could look for a PS flight with R space (very rare nowadays I think) and use the GPU to get the lie flat seat.
