A great resource for jumpseating is the alpa app if you don't have it, covers listing procedures for most airlines pretty good.. but for Kalitta if you go to their website and look for supernumerary travel you'll find the form you need to fill out and either fax or email in. Needs to be done at least 24 hours prior. The flight leaves every morning around 03:00 (get there early cause they'll leave early if the cargo is loaded and ready) except for Sunday and Monday morning. You meet the ground crew over by the Cathay pacific cargo area just off century blvd and they drive you to the plane. Haven't been on the 400 yet but the old ones were pretty comfortable and the crews were always real nice! Good luck!
