Hi there,
I am from the charleston area, and used to be a res. supervisor for an airline. $260 is a mediocre fare right now from CRW. I've seen a lot higher, and a bunch that were lower, as well. I've done priceline, and hotwire when our flights were booked, and I knew that I could not use passes and got tix on another airline for 150 less than what our flights went for.
Driving to another airport as Gale suggested is an option, but for me it depended on how many people were going, time involved, etc. If I were going by myself it would not be worth 3.5 hrs travel each way, gas, parking to save $100. If I were paying for 5 tix, it would be "load up the car, kids, were goin' for a ride!"
If you would like, you can email me direct with your info--how many, when, what time do you prefer, etc., and I'll see if I can steer you in the right direction.
GO MOUNTAINEERS!!!
