Flight 815 wasn't supposed to crash. In fact, it seems like a number of the survivors weren't even suppose to be on the plane; Jack, Sun, Jin, Hurley, and Sayid barely made it on to the flight. The universe was attempting to keep them from getting on the plane. Jack was held up at customs, Sun was supposed to leave Jin and walk out of the airport, Sayid was detained by security, and Hurley's bad luck almost caused him to miss the flight. Unfortunately, they all boarded the plane and it crashed.
In season 5, Farraday claims that the survivors can use the H-bomb in combination with the Swan Station's electro-magnetic forces, to make it so that Flight 815 never crashes. After much convincing, they do so. The show ends with a surge of white light. What happens after that? They achieve their goal, and none of them crash on the island on Flight 815, because they were never supposed to.
They were, however, supposed to come to the island eventually, on Ajira Flight 316. The oceanic six have been living their normal lives without any interruption in 2004, through the present. In 2007, they all end up on the Ajira flight, which crashes on the island.
In the Pilot episode of the series, when Jack wakes up in the jungle, the expressions on his face are strange, demonstrating a feeling of near-deja vu. This suggests that the survivors will return to the island after the flash of white light in much the same manner as they originally arrived there. This time, however, they will be profoundly altered in one of two ways: either a conscious or subconscious memory of past events which allows them to act in a a more productive and informed manner, or a character alteration according to Jacob's involvement in their lives. Perhaps Kate will have ceased running due to the influence of Jacob's lesson, Jack will have more confidence in his own abilities, Sayid will have found Nadia no longer carry the guilt of torturing, etc.
The survivors will come to the island in the manner that they were ultimately supposed to have arrived. The universe will have course-corrected to set the stage for the final island showdown.
This theory was first proposed in late season 3, and then refined by the events of the season 5 finale. It is a collaborative effort between AVREY_97, D'zle, and Losty09.
