I've used FedEx and even gotten next day delivery!
For a price, Ugarte, for a price.
FedEx works for us consistently!
For four or five years, I spent a lot of time in Memphis. My recollection is that FedEx had two runways at the airport which were exclusively for its use. "FedEx Air," in addition, formerly was the largest (in terms of aircraft) airline in the world . . . don't know if it's still true.
