Ain't nobody got time for that
http://en.wikipedia.org/wiki/FedEx_ExpressI love the helpful replies on jc. I guess I will go back to ppw.
Quick google search turns up that result, from there you look at all the feeders in the US.Westair, CA, MAC, Empire, CSA, wiggins and baron.
Then I went on each respective website (assuming I didn't already know who operated what areas) and found their route charts
So you have Mountain Air:

and CSA

You could also figure this out on flightaware but since you asked fedex, it's much easier this way I think. they might not operate dayton per se, but they do operate in that area of the state sort of.
The maps don't quite show what the schedule is like or what the base is. You have to flightaware that and make some educated guesses.
