EJM is an aircraft management company, which means someone decides to buy an airplane, but doesn't want to deal with MX, crews, etc., so the owner contracts with EJM. It's still the owner's airplane, but EJM takes care of MX, crew training and so forth. As a EJM pilot, my understanding is you get married to an airplane. Since its the owner's airplane, you fly when the owner wants to fly -- nothing at all set or predictable. If you have the time, in my opinion, you'd be better off going with a fractional like NetJets where you do have a set schedule. Hope that helps clarify it....
