I can drive for 5 hours, or take the 1 hour flight. The one hour flight has a total time of over 5 hours when you include getting to the airport, clearing security and getting bags at the other end. Plus I will not have a vehicle. For one person the cost is probably a wash, for two or more driving will be cheaper. 1000 miles does tip towards flying. Under 300 miles driving is going to be way less hassle to drive.
