Thanks for your answers KARFA and Globaliser - I only realised this morning that my card expiry was 2023 and not 2022! Annoying, because if I had realised there was no pressure to collect TP I might have taken the opportunity to try out some different airlines and routes. Anyway, first world problems and all that, and good to know there isn't any time pressure to chase up my missing QF flights.
Thanks both!
