Anyone asked CLT staff why the hours were shortened? Understanding might help predict when they will be extended. 7 - 3 is eight hours, which might mean they are trying to operate with a single shift.
I'd love to but my last connection at CLT was from 3:30 PM to 5 PM, my next connection will be from 7:30 PM to 8:30 PM, the one after that from 5:30 PM to 6:30 PM etc.
