Pure speculation, but...
While the A380F may well have a lower tonne-km cost than the 777F, I wonder whether its larger size would result in significantly longer loading and unloading times. Those times must be quite important in the overnight package delivery business.
Might worries about these times be an additional factor in FedEx's decision? "Cheaper in the air, but could we still meet our schedules?"
Isn't the overnight business more time-sensitive than price-sensitive, if the price difference is not large?
