To sort this mess out quickly I believe the best result would be some airline crew, preferably on an overnight away from home base, are tested and happen to be involved in these "false positives" read screw ups. The cost will affect the airlines and they won't be happy.
Accommodate 100 + pax, feed them, transport them and for what??
There is verty little I or you can do on our own.
CASA contractors, please check me and my crew. there are 6 of us, with some luck one of us will receive a "false positive" = a delayed or cancelled flight. watch QF jump up and down then!!
