With the C124 pop-up closing anytime now (still open as of 11/9), the C93 pop-up could be a squeeze for absorbing C124 and some of C72's overcapacity. It's laid out better than C124 and I could see myself residing here instead of C74. I went in early afternoon and it was almost completely empty. There were at least 20 more seats behind where I photographed.
An agent at this pop-up told me they ARE going to put another pop-up UC, but they don't know where or when. But I guess it's safe to say somewhere in C3 or C2, and in (late) 2020
