Not quite certain what applies regarding lounge access for me on my next trip, would appreciate feedback from the hive mind.
I will be flying GOT-HEL J and HEL-LHR J on AY, overnight connection, then LHR-BOS F on BA (all on one ticket).
I think I have just answered my own question, but which lounge will I have access to in HEL?
Since my TATL F is on another day it will not come into play as far as lounge access in HEL, right?

Thank you
