Flying or Greyhounding; Which is the best and cheapest?

So, I live in Baton Rouge, LA...I;m trying to book a flight from Baton Rouge, LA to Suffolk, VA around September, October, January, or February...Somewhere in between those times. I want the trip round-trip with hotel accommodations. Basically, I need to know how much will this trip cost me, which airline is the cheapest, and where is the closest airport from Baton Rouge, LA to Suffolk, VA? I;m 21 and I;ll be going by myself to see a friend.
