FedEx has purchased some Boeing 757 and have Boeing 777 on order but they have not been converted to freighter. The first Boeing 757 will enter operational service in June 2008. The Cessna and Twin Otters are operated by the feeder operations.
The DC-10 will burn approximately 15000 pounds of fuel per hour at cruise, which is equal to 2143 gallons. Divide by 600 miles = 3.57 gallons per mile.
