Okay - I've been checking for weeks and finally pulled the trigger today. I couldn't believe the airfares to Savannah from Newark - $450 if I left at 6:00am on Sunday (and miss brunch), over $600 otherwise.
So then I checked Jacksonville, but even there, the flight home on Sunday would have meant me high-tailing it out of Savannah to early but finally this morning success.
I arrive in JAX at 2:54pm and my flight out on sunday night is 8:10pm.
If anyone is arriving/departing about that time and wants a ride, let me know.
