But one very lucky Louisiana terrier was reunited with his family after four years on the road thanks to a free fare from United. Sam, a 10-year-old Yorkshire terrier, disappeared during the summer of 2011. His owners, the Lambert family of New Orleans, were heartbroken. But on April 14 they received a call that their dog had been found in Cedar Rapids, Iowa— almost 1,000 miles from home.
