This unique map called WiFox shows free WiFi spots along with their passwords for airport passengers so you can kill time before the flight.
You know when you miss your flight or when there is a delay in the flight, and there is nothing you can do but sit at the airport and wait for our turn? That is the time you may want to connect to the publicly available WiFi, but the network is either insecure or asks for your credit card information.
