Jetstar package - starter fare bundle

that stupid jetstar package that you buy so if there is a problem you can change the name is a joke and a way of extracting more money out of its victims. you buy it thinking ok ticket is paid for bum on seat so change name option is great..... well what happens is the prices then if are different somehow you end up paying at least another 400 dollars just to change a name on a ticket..... love the way Jetstar loves to just get more and more money.... really changing a name is that difficult... that it will cost another 4-500 dollars
