Jackie is a dog. A Doberman to be specific.

He likes eating carrots, barking at squirrels and lounging in human laps.

He is also key to an ambitious plan to turn around an airport that historically receives some of the worst marks in passenger satisfaction surveys. (Travel + Leisure magazine called it America’s second-worst airport in 2012.) Beginning today, LAX will unveil its “Pets Unstressing Passengers” program, or PUP, to use the acronym preferred by airport officials. The goal: To keep waiting passengers calm.
