NM, I had a short career in airfreight. If we had enough freight to cover the operating cost plus a little we put the planes in the air. Can't survive long that way but when your capital is leased or hocked to the bank it is costing you just sitting there. Every dollar over operating cost is a dollar you would not have otherwise. Don't know if that was the situation you observed or not. Of course when something greater than your margin breaks you wished you left it parked. Ron
