It's about a two hour drive either from Atlanta (traffic permitting) or Columbia, according to Google maps. There is also Greenville-Spartanburg airport much closer, but I don't know how expensive it is to fly there, or even what airlines do.
Google it
Quick search yields these companies that rent out of Greenville Airport:
I would not be concerned. Hoping to make it myself, should be a great time.
I'm actually kind of hoping for some rowdiness to be honest, but all in all, I haven't heard a bad thing about that fanbase. Definitely going to make getting up there a priority.
Don't know if you can still do it, but a friend of mine and I are flying into Savannah via Atlanta for the game. Now Savannah is considerably further from Clemson than Atlanta is, but the airfare to fly into Savannah is considerably less than flying into Atlanta directly. So we are going to get off our flight in Atlanta and head to Clemson from there. And get on our flight from Atlanta to Syracuse (checking in electronically), shunning the flights to Savannah both ways.
Can you do that and just not use part of your ticket. Especially on the 1st leg of the flight back. It makes sense, just didn't know if it was "legal".
I thought it was verboten. You can skip the 2nd leg but if you miss the first leg your entire ticket is cancelled. I would double check that.
Only thing is, I think to Charlotte is a cheaper flight.
