This article describes differences between the two different timelines shown in Season 6, up until the moment that (in the original timeline) the plane broke apart. Note that this article describes circumstances in existence at or prior to the moment that, in the original timeline, the plane broke apart, even if the audience does not learn of the existence of those circumstances until later (such as the absence of the coffin, which is not revealed in the flash-sideways timeline until after the plane has landed).


Oceanic Flight 815

  • Original timeline : Oceanic Airlines Flight 815 crashes on the Island.
  • Flash-sideways timeline: Oceanic Flight 815 doesn't crash on the Island. A plane, only later identified as Oceanic Flight 815, experiences a few moments of turbulence, but then lands uneventfully at LAX.
  • Original timeline : A flight attendant announces over the plane's PA system that the flight is experiencing turbulence immediately before Oceanic Flight 815 crashes.
  • Flash-sideways timeline : After it passes the unseen pilot reassures the passengers over the PA.
  • Original timeline : Oceanic Flight 815 lost radio contact and was over 1000 miles off course (heading towards Fiji) during the time of crash.
  • Flash-sideways timeline : The flight lands uneventfully at LAX without any indication that the plane lost radio contact or was off course.

The Island

  • Original timeline: Thriving with life and multiple inhabitants.
  • Flash-sideways timeline: Although it appears to have been inhabited at some point (the ruins of the four-toed statue, the Sonar Fence, and of the Barracks are shown, as well as a shark with a DHARMA logo) the entire Island is now at the bottom of the ocean.

Jack Shephard

  • Original timeline: Jack obtains two bottles of vodka from Cindy and remarks that her gift must break some crucial FAA regulation. When Jack looks out the airplane window, the wing of the plane is visible but obscured by clouds. Jack reassures Rose, as Rose is a nervous flier. Jack is sitting in row 23. His hair is cut short in a buzz-cut. He uses the pen in his jacket pocket to make an incision on the injured Edward Mars.
  • Flash-sideways timeline: Jack obtains only one bottle of vodka from Cindy and remarks that he will keep her gift a secret. When Jack looks out the airplane window, the wing of the plane is not visible. When Jack looks in the bathroom mirror, he notices a bleeding cut on his neck. Rose reassures Jack, as Jack is a nervous flier. Jack is sitting in row 24. His hair is longer. When trying to resuscitate Charlie, the pen in his pocket is missing because Kate stole it when she "bumped" into him outside of the bathroom.
  • Original timeline: Has no children. Did not have an appendectomy prior to Flight 815 (with the result that he would need one later while he was on the island).

  • Flash-sideways timeline: When the plane lands, an Oceanic Airlines representative tells Jack that the coffin containing Christian's body which was checked in the cargo hold in Sydney is not on the plane. Jack Shephard is informed by Oceanic employees the coffin was "apparently" never loaded onto the plane in Sydney.

Charlie Pace

  • Original timeline: Charlie goes to the first-class restroom to use heroin. He snorts some of it and dumps the rest down the toilet right before the plane hits turbulence and crashes. His hair is shaggy and unkempt.
  • Flash-sideways timeline: Charlie attempts to swallow a bag of heroin in a restroom in the tail of the plane, but it lodges in his airway and he almost chokes to death before being saved by Jack and Sayid, much to Charlie's dismay. He is arrested when the plane lands. Charlie's hair is a short buzz cut.
    • The same hair cut he is using when he visited Hurley at the medical institution in The Beginning of the End, season 4.

Desmond Hume

  • Flash-sideways timeline: Desmond is on the plane, and moves from his original seat to sit next to Jack while Jack is using the bathroom. Jack returns to find him sitting next to his seat reading and Jack asks whether he knows Desmond from somewhere (they never come to a conclusion that they do). Later, Jack returned to his seat for a second time, following his treatment of Charlie outside the bathroom. Desmond is no longer in that seat, or anywhere within Jack's view. When asked, Rose states that she and Bernard were sleeping, and are thus unaware of Desmond's whereabouts.
  • Original timeline: Desmond despises Charles Widmore, who regards his son in law as a low-class man, unworthy of his daughter. Charles says that Desmond is not worth the cost of the MacCutcheon whisky.

Rose Nadler

  • Original timeline: She was nervous on the flight; Jack tried to keep her calm. She says to Jack, "My husband keeps reminding me that planes want to BE in the air". She had her husband Bernard's ring, saying she always kept it for him when they flew because his fingers swelled. Charlie ran past Rose on the flight.
  • Flash-sideways timeline: She was the more calm one on the flight, whereas Jack was more nervous and Rose tried to keep him calm. She says to Jack, "My husband says that planes want to STAY in the air". Bernard was wearing his ring. Charlie does not run past Rose on the flight. She is employed at a temp agency.

Bernard Nadler

It is not clear whether the knives disappeared from the plane in-flight, whether they were never loaded onto the plane, or whether they have simply been misplaced by the airline.
