Bubbles23 you can remain on QF and it will earn on BA And QF Gold (oneworld Sapphire) will give access to the BA lounges when flying to Europe.

QF generally a good program for paid premium flights (due to SCs) and other big advantage is the lifetime status points if you're anywhere near.

If planning a long stay in the UK or moving permanently worth looking at Avios due to the ability to get UK credit cards etc.

May also be worth putting cheap Economy fares on BA as only YHB earn 1:1 on QF, GKLMNOQSV earn 0.25:1 as well as minimum earnings.

Unlikely that BA will match your QF status. Maybe might match Velocity (as different program)


Velocity less useful in the UK, although could still earn points if flying Singapore or Ethiad to UK.
