The best cities for Southwest to start flights to in Georgia are SAV and AGS. Savannah is close enough to several tourist destinations (Hilton Head & Jekyll Island) to warrant bringing a little LUV to the area, and considering that the only other low-fare service out of SAV is FL to ATL, they could do well there.
Ordinarily, I would disagree with you, simply because JAX is only a two hour drive from SAV. However, from what I've read, Southwest is gate constrained at JAX. They only have 2 gates and I think the prospects of them getting any more anytime soon is slim to none.
Back in January of this year, Southwest celebrated its fifth year in JAX and these sttistics were included in the press release:
During the last five years Southwest has grown to capture more than 17 percent of the Jacksonville market share.
Before Southwest started service to Jacksonville, there were 259,880 passengers carried to cities served by Southwest. As of second quarter 2001, there were 610,990 passengers carried, an increase of 135.10 percent.
Before Southwest started service to Jacksonville, the average fare paid was $144. As of second quarter 2001 the average fare paid was $113, a decrease of 21.53 percent.
During 2001 Southwest transported more than 870,000 Customers in Jacksonville.
To have a 17% of the market share using only two gates and 22 daily departures is pretty impressive, IMO. It makes me think that if they could get their hands on more gates in JAX, they'd add flights in a heartbeat. I wonder how many JAX passengers actually live in/near SAV. I wouldn't be surprised at all to see Southwest go into SAV because of the gate shortage in JAX, just like they went into PBI because at the time, they weren't able to get any more gates in FLL. I'm not sure what the gate situation is at SAV. Does anyone know if there are any that are currently vacant?
