QF is not to blame.
Tiger is the crap company that is allowed to operate in Australian airspace.
They should be banned for their continued poor attitude toward the Australian public. All I can see, is the foreign owner's laughing at what they can do and get away with on a daily basis.
Qantas is then left to clean up the mess. This sh$t situation had a positive outcome. It is not exactly as you guys would like it to be scripted, however they did their best.
She got home, and so did the dog, she flew Qantas... game over, Qantas got her home.
Get over it.
