You will definitely have to do two legs to get there. Your safest and most reliable bet would be JAX-DCA-MCI or JAX-IAH-MCI. Both of those options put you on company metal for both legs. Via DCA you're on the American side so they will clear you for a seat before the D1's which is incredibly helpful. Via IAH you will be on the United side and you'll get SA0X priority which will put you at the top of the standby list (below UAL vacation pass travelers). With both options you are guaranteed the cockpit jumpseat assuming there aren't any other Republic pilots commuting.
