The only thing I can imagine that would require such an early arrival is checking bags onto an international flight.

Since anybody who has the option to fly private is almost certainly flying in F, there shouldn't be any waiting in lines (and escorts to the head of security, if necessary).
If I'm flying out of an East Coast airport and don't know what the combination of traffic/parking shuttle wait time/baggage chack/TSA is going to be, I allow a ton of time and frequently do end up there 2 hours early. It would be silly at MCI, my home airport, but I once flew out of HPN and needed those 2 hours. And in our company if you need to be at HQ and your schedule coincides with the week the charter flies, you're on it- so it's not just execs who'd be in F. (And most execs are required to fly Coach if net air time is 5 hours or less.)
