According to his lawyers, Epstein supposedly sold the Lolita Express in June, BEFORE he was arrested. 

Ep. still owned a Gulfstream G550 but not the infamous Boeing 272-200 known as the Lolita Express. No one has yet said to whom, he sold it to. Until that is known it really isn't Epstein's plane but someone else's making the flights that have been reported.
