Avios on a Codeshare Flight
 

Afternoon, departing tomorrow on my GLA-TLL jaunt tomorrow.

I have noticed on the booking that it states that it is flight AY832 sold as BA6032 and I am in Class C.

Having checked the BA website it states that this will earn 3119 avios as a Bronze as a BA flight but only 1418 if it's a Finnair flight.

To further complicate matters this is a holiday booking.

Am I correct in thinking that I will earn the 3119 and not the 1418 avios.

Small matter I know considering the flights were so cheap but thought best to ask.

Yes.

If you're on a BA coded flight you'll earn more avios than on an AY coded flight. The operating carrier doesn't matter in this case as you are booked on a BA flight number (operated by Finnair).
