Technically, you are not prohibited from leaving the airport, but doing so during a 1-hour layover is physically impossible and would result in you missing your connecting flight. A 1-hour window barely covers the time needed to deplane, navigate the terminal, and reach your next gate for boarding, which usually begins 20–30 minutes before departure. Even in the most efficient airports, the process of exiting through "Arrivals," passing through immigration (on international flights), and then returning through security can take 45 to 90 minutes on its own. Furthermore, most airports are located at least 20–30 minutes away from city centers. Travel experts generally recommend a minimum of 5 to 6 hours for a domestic layover and 7 to 8 hours for an international one if you plan to leave the airport for a meal or sightseeing. If you only have 60 minutes, your best strategy is to head directly to your next gate or, if time permits, grab a quick coffee at a nearby terminal kiosk.
