Same here. For east coast delivery, there's a flight from Anchorage to Memphis that leaves today at 3 pm Alaska time, but that may not allow for enough time between legs. In that case, it probably sits in Anchorage until tomorrow.
The estimated Tuesday delivery is looking more and more likely...
FlightAware also shows a 3:50 Alaska time flight to Memphis, which I hope it gets on.
EDIT: It got on the plane! FedEx Tracking shows it departed the FedEx Location, and FlightAware shows FDX28 from Anchorage to Memphis departed 16 minutes late.
