Good Morning!

After searching the forum I couldn't find much on who to contact in an effort to set up reciprocal jumpseat agreements with United. I was hoping someone may have a point of contact they can refer me to. I fly for a small 121 CRJ operator flying routes from Vero Beach FL to Newark, Branson MO to Denver and Houston. Also Chicago/Rockford to Fort Collins. I was hoping United might bite on these pairings. I appreciate any help, Thanks!
