When is your trip and how full is the seat map? If you're seeing open C+ aisle seats, I suspect that you're traveling far in the future.
I think the odds of someone without status getting an aisle seat for free on a full flight is very small, although you can always get lucky at the gate.
Do you currently have a relatively decent nonaisle coach seat such as a window?
