"If I manage to travel without a checked bag, would I be able to turn around on the same plane that took me to CLL? It's a 30-minute turnaround. I imagine this would not be without risk, as the bag would likely be big enough to warrant gate check on an ER4 cropduster"
I don't know if the procedure is different on ER4s, but when I have to "valet check" a large carry-on when traveling on a US turbo-prop, the bag is returned plane side on arrival; it is not delivered to baggage claim land side. If the same procedure is followed at CLL, then I don't see why you could not do a fast turnaround there.
