I don't know the ins and outs of this case but I can say this. Nobody has the right to force anybody to fly unless they are a prisoner of the commonwealth.
That was my understanding too. IF (and it's a big if) this guy's story is kosher and he just wanted off after seeing what was going to transpire QF have to cop it sweet.
Be interesting to see if he takes this further in court as I would suggest he may need to fly for his job.
If the guy voluntarily offloaded himself because he just got a call that his wife was taken to hospital due to a car crash, would QF still ban him?
