The USA3000 connection is not a big one. C3 for a few years has operated charters out of Newark for Apple Vacations. Apple is now starting it's own airline, USA3000 to do basically what C3 was doing for them for the last three years, plus a number of new charters out of NYC and the east coast. Angus Kenear the CEO of C3 owns a chunk of Apple Vacation stock, a rather large chunk, and the CEO of apple vacations own some C3 stock, so in a way they are connected but not as much as C3 and A2K were, USA3000 has a nicer livery, but not by much.
