if possible i think this would be the best way for me. then find a AA flight from Reagan to LAS (if possible) and get the extra TP's that way?

Apparently I need 20000 Avios + £ 1,250.96 for a return upgrade?
Unfortunately AA dont do any direct flights and I'm not that desperate to earn miles or TPs lol.
