Milwaukee's Mitchel Airport has a creepy deserted terminal that I never knew about until I flew through it last week. Since Frontier changed their hub operation in Milwaukee to a lonely outpost, there are just two flights to Denver and a less than daily one to Mexico. For this minor operation, Frontier has 26 gates and an entire terminal to themselves. There were several restaurants, but only one is open. The closed ones still had all the fixtures and supplies to open any day, but are deserted. The ground level gates with zero flights a day sill had a moving walkway and escalators running. It is an airport ghost town

I'm surprised the airport authority doesn't move Frontier to an unused gate (they only need one or could share even) in another terminal and close the D terminal until traffic picks up enough to necessitate it. The costs to keep a terminal up and running must be exorbitant and Frontier's landing fees don't cover the operation. It would also remove a creepy ghost town, it was seriously disturbing (Omega Man?).

MKE still has a cool airport museum, I enjoyed browsing through it again.
