The math does pencil out for Boston to New York. I'd be an hour to my local airport, arrive 2 hours in advance (could cheat a bit with an early flight--it's taken me almost 2 hours to get into Boston near rush hour--especially given basically a commuter flight but a good hour drive in), probably an hour for a shortish flight, baggage claim (if relevant), then transportation into the city.

Were I amenable, which I'm generally not, could probably drive 4 hours from my house into the city. (Almost always take the train.)
