If you find yourself bored on a flight before November 18, (and have a computer with you), you donâ€™t have to ante up the $12.95 for in-flight Internet just to mess around on Facebook. There is a way to get to there for free. And itâ€™s fun. GoGoInflight.com and Ford have a mutual promotions running till then. So all you have to do is go to Ford.com and design your dream Mustang. (Mine — above — matches my new nail polish.) Then share that design on Facebook. That will unlock the gates to Facebook for the duration of your flight.
