I can almost guarantee that the majority of the population don't give a sh*t about Qantas Pilot for Qantas Aircraft, they just want the cheapest fare.
I don't work for Qantas, but i can almost guarantee that you are wrong with this statement. If they just wanted the cheapest fare they probably wouldn't be flying with Qantas. Qantas passengers are probably there for exactly the reason you're fighting for, so they will most likely be the most sympathetic of the travelling public, and whats more, they are the ones that are capable of sending the message to management through their choice of airline.
I was speaking to a doctor last week who knew naff all about flying but said that safety was high on his list of important factors that influence his decisions. He flew Qantas when he could.
