Silver can select seats at the time of booking, with the exception of exit row seats on long haul flights (some folks miss this nuance)

Of course that I am well aware of the requirements regarding exit row seats on long haul flights. I have been around for quite a while.
Also, I have been on BA94/BA95 many times over the last decade or so. That's why I would not expect any surprises of this kind.
