If airline travel has got you down because of another wayward suitcase, place a TrakDot GPS device in your bag the next time you hit the road. The device, which runs on AA batteries and can be linked to multiple cellular phones, tracks your luggage and alerts when you are within 30 feet of it. Trakdot can sense when it is flying, so it “sleeps” to save battery life and “awakens” when it lands.
