Sorry but I've done a search and can't find the answer.

Trying to pin down the miles I will earn on a BA flight but QF codeshare ticket.

The only difference in the mileage if it was QF metal seems to be that First earns 100% bonus on BA but 50% on Qantas.

However if I am flying on BA metal but with a QF code do I still get 100% bonus flying upfront or do I lose out and get just 50%?

Thanks,
