A woman says she was forced to carry her disabled adult sister off a Jetstar plane and drag her through the airport after the airline failed to produce their wheelchair upon landing in Perth.

Danae Florias, 24, dragged her 26-year-old sister Marissa, who has cerebral palsy and requires her specially designed chair in order to sit up safely, through Perth Domestic Airport after Jetstar staff gave her blank looks and no answers as to where the chair was, she told Radio 6PR on Thursday.

The sisters were returning home from a holiday in Melbourne on October 29. As luck would have it, Jetstar CEO David Hall was sitting in front of the pair, and they chatted with him during the flight, Ms Florias said.

The women told him Jetstar staff had been helpful on the other flights they had taken during their trip, and he advised them to post a thank you comment to the airline's Facebook page if they wanted to provide some feedback.
