Jetstar exploits woman with Down's Syndrome for positive PR

Recently there was a woman with Down's Syndrome named Georgia who dreamed of being a member of the cabin crew. Did Jetstar give her a full-time job? Nope, they hired her as a flight attendant "for a day". As a disabled person myself I found the whole thing patronizing. Why don't they offer her an actual full-time job? It's clear they just did this for the positive PR and so media consumers can have their feel good inspiration story.
