She dragged herself out of the Wheelchair and onto the stairs to pull herself up the stairs. I assume at that point a member of the public or staff might have been able to fold it up and carry it to the top but staff wise I believe it would depending on what rules there are for Manual Handling.If the woman was a wheelchair user, where was it? How did it get up the stairs?
On her Instagram there is a video of her dragging herself out of her Plane seat and to the Aircraft's toilet via the single aisle. Some flights have accessible like wheelie chairs but many don't as its not common law as far as I know, which I assume she is trying to raise awareness to of sorts.
