True priority seating, at least from my AA experience, is being able to prereserve, and not only during online checkin, good seats, be it front rows or emergency exits.
Actually exit row seating is not preferential on LAN, someone (actually anyone) could have booked it online at OLCI so you were told it was occupied and then they subsequently failed to turn up for their flights.
Given the quality of seatguru's seat maps and LAN not marking the exits as premium seating, it is entirely likely that someone booked it without even knowing it was an exit seat... And then didn't fly it.
