Runaway suitcase chases gate change

Vertical airport vlog.
A creator stands beside her wheeled suitcase and says:
“Gate changed again.”
She looks down at her phone.
Her suitcase suddenly starts rolling away by itself.
She notices and runs after it.
The suitcase moves quickly through the airport concourse, smoothly navigating around benches and travelers while she chases it with the phone camera.
It turns down a corridor.
She catches up.
The suitcase stops perfectly beside the correct departure gate and extends its handle upright.
She arrives out of breath.
Looks at the suitcase:
“You could’ve waited.”
Fast travel-vlog energy, realistic wheel physics, continuous chase, natural airport ambience.
