I'm guessing that the flash-forward took place about half a year later. It probably took the tankers a month or two to get them off, and then, for the next few months, Kate got back to a normal life and Jack went crazy. There was also some theory I heard, that Jack's phone in the flash-forward was a newer brand of phone, that wouldn't have come out before they were on the island. I'm not sure how recently it did come out, but I you researched this, you might have a clue.
I sort of agree with your destiny theory, but you could also argue that now that the flash-forwards have been shown, they are the present, and everything else is flashbacks leading to them getting off. Not really flashbacks like "oh, this is parallel to my old life so now i'll think about my past", more like all of the facts leading to a climactic middle point off getting off the island, where the opposite will then follow, and they'll try to get back. So in a way there are two stories going on: the getting off and the getting back.
Sorry for all that; I think I've word vomited as well.
