NZ X Man,
I too read this article with interest. The impression I got was that while the aircraft was 'waiting' at the non fixed location, the crew were re-deployed. I guess it makes sense - using your example, flying a crew back on commercial airlines from say, Nice, would be a fraction of the cost of repositioning the frame on a deadleg. Even if the crew then flew back to Nice a couple of days later, it would offer a considerable saving over deadlegging.
