And finally, is the plane still 2000 miles of course like it was originally? Changing the timeline shouldn't have affected things like the radio going out (unless the plane was brought to the island on purpose) of course it should also not have affected Cindy only giving Jack one bottle of vodka and not two. So who knows?
According to many of the spoilers, the timeline wasn't changed by the bomb going off. The alternate timeline we see is different in many ways from the one we remember, not just that the plane never crashed, but events even from before that are different. And according to someone who's seen the premiere (see one of the last pages of this thread) there is not yet any indication of what this alternate timeline actually is.
