When checking a bag today at BA, the agent said there was a new TSA-pre (only) checkpoint at the west end of Terminal A west.
And there was! It dumps you next to the Illy location where A-east jogs a bit, close to A17.
Apologies if this was already reported, I scrolled back a ways and didn't see mention. Don't think i've been at PHL since maybe mid 2023 so it's all new to me lol.
