Narrative:

Upon arrival at burlington airport, after aircraft was parked, fuel truck pulled up and began fueling the right outboard wing tank. I told him to stop fueling until I could confirm needed fuel with operations/dispatch. I was informed by operations that this fuel truck was at the wrong aircraft and should be fueling another company aircraft that was just being parked. I informed the fueler, who climbed the ladder next to the wing, of his error and continued my walkaround preflight for the next leg of the flight to plattsburgh, ny. After start-up and taxi out to the runway with all checklists completed, we took off and landed in plattsburgh normally. At that time a company employee passenger on the aircraft informed me that he saw the latch on the cap 'up' on takeoff roll and that it was missing on landing. Part of the takeoff checklist calls for captain and first officer to check their respective sides for the security of the fuel caps. Suspect that as I continued my walkaround, fueler did not secure cap and that during takeoff checklist, first officer failed to visually check the fuel cap security properly. Cap departed aircraft somewhere between burlington and plattsburgh.
