IAD Polaris lounge (2020?)
Yesterday on a tight connection I got a ride on the tarmac (always a bit embarrassing, but at the same time very much appreciated!) to my connecting gate. Due to some traffic we had to park on the opposite side of the concourse from my gate (C17). A big section was roped off at ground level, with some early construction work beginning (looked like clearing space and other prep work). The very nice GS agent explained that they were at long last starting construction of the Polaris lounge! She said they were losing one gate (appears to be C20 based on where we were) and that some UA office space was being relocated to make room. Glad to see this is finally getting started.
