Executive Jet Management (EJM) said it generated more than $32 million in charter revenue last year for its managed aircraft owners. The keys, according to the Cincinnati-based company, are owners who are eager to make the aircraft available for charter, crew availability on short notice and stationing of the airplanes in accessible locations. Of 32 managed aircraft available for charter, one produced $5 million in revenue, three surpassed $3 million and four produced more than $2 million.
