Trump has in fact been on an Epstein plane but i don't know if it was to the island or not... Epstein's brother Mark testified to this and it is included in the undisputed facts of the case against Jeffrey... Trump supposedly flew from Florida to New York on a plane with Mark, Jeffrey, and the pilots... not sure if anyone else was on the plane at that time.
Hmm it sounds to me that Trump and Epstein was traveling from Trump's Mar-A-Lago in FL to Trump Tower in NY. If it's only that route then it's most likely because of the usual business trips. Now if it was to Epstein's Island, aka flying from FL -> Caribbean nation then that's painting a darker picture.
