Welcome yanflyer
Greetings yanflyer, welcome to Flyertalk, welcome in particular to the BA board. Thank you very much for the question and thank you for joining us here. Please make yourself at home and continue to post on this and related topics.
I haven't got much to add to the advice already given. Basically TPs are rigourously personal and relate to you specific travel. I don't know about Bronze but for other status levels you can ask for TPs from 2 weeks after your year to be taken into consideration. However note there is an alternative advantage in getting a higher status level early in the membership year: you get that status for the rest of that year, plus the year afterwards.
You get 10 TPs on domestic runs. You can get some trips to Glasgow and Jersey without bags from Gatwick for below £80. LHR is generally a bit higher, but the same principle applies.
