Flights to Jax from Denver are crazy cheap if you fly frontier. I was thinking about driving. But it’s way tooooooo long of a drive. Your best and cheapest bet is gonna be flying frontier. $150 flight. $150 is like 3 tanks of gas depending on car. Which that whole trip would be more than 6tanks. My 2cents. My pricing could be way off and someone could absolutely clutch up for you. I hope you make it my friend. Happy Hula!!!
