Character Reason for being in Sidney How they got their Ticket

Jack Shepard Getting Fathers body We can assume that he bought his plane ticket


I don't think we should jump to the conclusion that Jack bought his own ticket to Australia. It was Jack's mother's idea that he go there in the first place. Jack didn't even know his father was missing until his mother told him. Then his mother guilt-tripped him into promising he would find Christian and bring him home.

I'm not saying that Jack's mother was part of a conspiracy or anything, just that she probably bought the ticket.
