Rather than just attacking the OP, maybe look at the issues that was raised - conflicting information given by Jetstar.  Even on a LCC the message should be the same!   And the bit about the OP being special and wanting his 'livelihood' looked after etc ... I think that's un-necessary.   If the person is a doctor, with patients waiting for surgery etc, I think that's worth mentioning if the OP is having a personal self described 'rant'.  I hope everyone's doctor here would express similar frustration if they missed appointments due to circumstances out of their control (at the time) and personally, I wouldn't relate it to a possible impact on their income.   YMMV.
On the other hand, I agree with sentiments that the OP might have avoided being put in this compromising situation by avoiding LCCs in general.
