Yes, I think just about everybody agrees on that sequence. I ust find it odd that the Kate/Jack airport flashforward is to a date in the future relative to the date the episode aired. As far as I can tell it is the only one like that. And the timeline on lostpedia has yet to concede that the airport meeting occurred after August 2007. But given the response to my posting on this issue, it seems no one else finds this to be significant, so I guess it isn't.
