I'm not sure what the situation with conx. is....if you are interested in booking though, call the reservations line at 888.958.9538 and they may be able to put an itenerary together for you.
You could do it manually with a connection in
SAT for about $500 round trip using the listed prices on xjet.com. There could be some long layovers depending on the day, as the frequencies out of
RDU aren't too high.
Hope this helps.....
