The first post refers to "all-inclusive" one way ticket prices. On reading this, the implication is that the "plus taxes and charges" bit is not the way Jetstar plan to do things.
I recently purchased a Jetstar flight for my father and on the website only one price was quoted, and that was the price I paid. There were no extra taxes and charges. All they did was identify the amount of GST paid. This is what the receipt says:
Jetstar base fare 253.64
Other Fees 0.00
Subtotal 253.64
GST Payable 25.36
Total Price 279.00 (this was the initial price quoted)
I am a Qantas pilot but fair's fair - Jetstar do not engage in the plus taxes and charges deception. They don't even do it for staff travel fares, whereas QF happily gouge their own staff in this respect.
So in the context of the above, I guess a few posts on this thread are emotive propaganda cr@p and really don't deserve to be on public display...
