Crank...
If you think 'Staff travel' is really 10% then your reality is somewhat distant too.
These days, it's often the case that Jetstar or Virgin are cheaper than the staff travel cost (depending on route and, yes, from first-hand experience) so airline people do buy commercial tickets for their travel needs. But therein lies the joke. QF keeps saying that staff travel, where you travel ONLY if there's a vacant seat anyway, is not covering costs!?! Staff travel NEVER displaces a 'commercial ticket', yet now sometimes costs more than that ticket. And as for the FBT argument thrown about: another joke.
Now, I don't gripe about bankers getting cheap loans, builders getting houses built for cheap, car salespeople getting discounts on their vehicles etc. The list goes on.
You could afford to chill a bit. Enjoy your journey.
