Since John Edwards is a skilled attorney, we can presume he knows this trip invites questions from investigators. From the Charlotte Observer:

On Friday, a Raleigh TV station showed Edwards at the Raleigh-Durham airport walking off a plane belonging to Rachel “Bunny” Mellon, a wealthy heiress who supported the former Democrat’s presidential candidate’s campaign.

Flight records showed the plane flew from RDU to the private airstrip at Mellon’s northern Virginia home. In 2008 Mellon’s holding company gave $3.48 million to Alliance for a New America, a 527 group tied to Edwards’ presidential campaign. Prosecutors investigating Edwards have talked to Mellon’s attorneys.
