So apologies if this is covered elsewhere, but if I book a flight between these 2 dates, and I will be soft landing from Silver to Bronze, do I still get some or all of the silver benefits for that flight?

Specifically seat selection, lounge access and additional Avios? And if the answer is yes, would that apply to just BA or all OW flights?

Quite important as its almost a 2 month period and I'm intending to do quite a lot of flying then to strategically lock in at least silver for another 2ish years...

thanks
