I'm not saying she is lying. Fedex won;t deliver on saturdays unless you pay for it but they will still transport packages (I know two people who used to work for fedex) and they have flown in packages on saturdays before even though they weren't scheduled to be delivered until monday.
Ah! I think I see what you're getting at. Well as I had said in previous post I too use to work for Fedex and I touched on this subject earlier. It's true that some packages may fly in on Saturday, but they may not come in till later that afternoon, well after the Fedex office for pickup has closed. They will sit inside containers at the airport until they are taken to the station on the next day that it is open. I spoke with a buddy who still works within my old station and he told me that he checked my tracking number and my package is still sitting in Memphis and will fly out tomorrow.
