First time checking in at EWR at the new Terminal A, with a reservation in Mint. Went through the self tagging process, and went to the agent. The agent make a comment about "you're just here to see me?" and pointed. I turned around and see this:
Yes, B6 now has a dedicated check-in lounge area for Mint and Mosaic customers (and presumably AA Elite for the near future). It also has a dedicated line for PreCheck, shared with United Premier Access lounge next door.
