Thanks - we booked in January during the sale so will definitely be under the nTP bonus, just trying to work out how many I can expect as at the higher level I could retain Silver but if the lower will need to book a few more flights.
Have completely given up on retaining my Gold under the new system, so trying to put the bare minimum required on BA to retain Silver, as it is almost as good as gold for non-London based travellers like us!
