If you check the excellent Tier Point Thread Wiki by Karfa you will find out how many TPs, by class, by airline you will get on your journey. Also it has a guide to which of the OW carriers give the higher Tier Points when you purchase an Airport Upgrade (AUP). There is a disclaimer after this particular piece which says that this is what members have found to happen rather than what the “rules” say. I have found it to be accurate so far, but have not tried with QR yet, YMMV.
