Not very true nor good answers. ABX does not allow international JS, with that said, we do not do a lot of international flying. For domestic operations we have reciprocal JS agreements with almost everyone so to speak (you must be in our CASS system). You can jumpseat on any segment, regardless of where it starts or ends. There are segments that never go thru CVG, so all legs are open. To list, simply contact our JS adminstration or for last min reservation our Flight Control/Following desk; all numbers should be in your airlines/unions information for JS on other carriers.

What the original answer referred to was our domicile for flight crews. All crews are based in CVG and therefore our trips begin/end there...nothing to do with JS though.
