Second red flag is the fact that her tour schedule is kinda "all over the place", and just seems to be random locations with no sense.
It'd be more believable if tour schedule consisted of Pensacola, then Biloxi, then New Orleans, etc. (in a straight line). But, her tour kinda zig-zags all over the place.
True, she could be "flying", but most normal people try to be efficient if touring.
