Airport, runway and elevation figures come from the OurAirports open database. Routes are calculated to the airport's map reference point, which at a large airport may sit a few minutes from your specific terminal.
Leave home drive time + 2 hours before a domestic departure from GUM, or drive time + 3 hours before an international one.
Those buffers cover bag drop, security and the walk to the gate, but not getting from your car to the terminal — at a large airport like GUM, allow another 15–30 minutes to park and ride in, or 30–45 if you are returning a rental car.
