To promote a baggage tracker tool on its mobile app, Delta recently fitted a passenger bag with cameras to show exactly where every item has to go on a typical journey.
From drop-off at Atlanta to pick-up in New York, the video shows the bag passing along the myriad of conveyor belts behind the scenes at each airport and being loaded and unloaded from the aircraft.
Safe to presume the Transportation Security Administration knew about the stunt beforehand - but for security reasons, unfortunately the most interesting part of the journey (the TSA inspection area) is blacked out momentarily.
