This is pretty funny. Looking at a flight ORD-PIT next week and the seat map for the flight (on a 757, for some reason) shows Economy, Business, and First. Howeva, C and F are the same seat map in different colors (F=gold, C=grey). Exact same seats showing available. I know it's just a glitch, and an inconsequential one at that, but thought it was funny. Given the Y seat map, knew it was too good to be true! Edit: You can even see that the pictures of the lie-flat seats to the right are different!
