This would be a mistake.
Even after adding on the "please be at the airport one hour before departure," you're only up to three hours.
Yet somehow, as nice as it all sounds, it took me more than six hours in each direction. A large chunk of time was occupied getting to and from the airport, but I also sat in a holding pattern over Chicago for longer than the actual flight.
Granted, it's not sitting on a plane for ten hours on a snowed-in runway, but for a quick weekend trip it's an eternity.
