April 23 (Reuters) - FedEx Corp said its FedEx Express subsidiary has entered into a seven-year express air transportation contract with the United States Postal Service for about $10.5 billion.
FedEx's current contract ends in September 2013, and the new contract will begin in October 2013.
The company on Tuesday also launched a new service to let customers select from a range of options to schedule dates, locations and times of delivery. Rival UPS began offering its "UPS My Choice" service more than a year ago.

Any and all USPS mail that is transported by air is moved by FedEx, letters and all. There MIGHT be a very small percentage of it that gets moved by commercial airlines.......the FAA had a big part of that 13 oz sticker you see on the drop boxes.... Ever wonder why there is FedEx boxes on USPS property? It is part of the deal.
