You lack knowledge of what causes delays in the FedEx system. Just because the winter storms are not in your area doesn't mean that the storms are not causing delays along the way.
You need to get a broader scope of the nationwide infrastructure. Think of FedEx as not only a freight airline, but also as a passenger airline.
Flights get delayed because of current weather conditions and forecasted weather conditions. Take a look at how many passenger planes were delayed or cancelled because of the severe weather across the northern part of the U.S.
Do you drive your car in sub-zero weather the same way you do when the temperature is in the 80's? Safety is a concern to all airlines, both freight and passenger, so just think about the overall picture when you complain that your Mickey Mouse paint by numbers book didn't arrived in two days during a blizzard.
