Download apps for a smartphone (Droid, iPhone, etc.) for real-time flight tracking. Open the app and enter the flight number, airline and date of travel and check the status of the flight.
Log on to any number of free flight tracking websites. Find these websites through a Web search on a major search engine using "Flight Tracking" for the search parameters. Enter the airline, flight number and date of travel to see real-time maps of the flight, and estimated times of departure or arrival.
Use widgets for desktop computers. Widgets are small apps that open quickly and rest in the corners of the screen with other applications open. As the smartphone apps, open the widget and enter in the airline, flight number and date of travel to get real-time flight tracking.
