Here is the new sign at B1 referring to C18 as the transfer point. In checking C18, there was no signage, but it was before the 11:00 run time for the shuttle. The gate agent told me there would be a sign in the boarding area. May be a bit chaotic as it’s a wide body gate with not a ton of space. I have a feeling the shuttle will depart across gate C18 by the elevator at the Concourse B-C escalator. I believe that’s where the employee shuttle docks.
