This is what happens when you check luggage. Watch as passengers look on in amazement as a spinner bag rolls on its own, away from aircraft and down the alleyway between American Airlines and Delta operations.
No one does anything to stop it, although in fairness it’s not really advisable to simply go running out on the tarmac — we can’t see in the video whether a plane might be taxiing in or getting pushed back.
Last year a bag at Heathrow was “blown by an engine draft for nearly 600 feet before it was stopped by panicking ground crew.”
The bag’s owner was lucky it wasn’t sucked into an aircraft engine I suppose.
