There were 324 people aboard Oceanic Flight 815 when it crashed on the island in Lost. The total includes the fictional flight’s passengers and crew, while the survivors were scattered across the plane’s three separated sections.
The crash initially left 71 survivors, counting 70 humans and Vincent, the dog. The fuselage survivors formed the show’s main group, while the tail-section survivors were separated from them and faced their own dangers. The aircraft’s broken sections helped Lost tell parallel stories about people who experienced the same disaster from different locations.
The number 324 is sometimes confused with the number of initial human survivors. Those figures are different: 324 people were on the aircraft, but only 70 humans initially survived, along with Vincent. Later events changed the survivor count further as characters died, disappeared, or left the island.
Oceanic Flight 815 was traveling from Sydney to Los Angeles when it broke apart over the island. Its crash launched the series and introduced the passengers’ intertwined backstories.
