Flight 815 in Lost departed from which Australian city?

Flight 815 in Lost departed from Sydney, Australia.

The flight’s planned route ran from Sydney to Los Angeles, carrying the passengers whose survival—and eventual separation—forms the series’ central premise. The plane crashes after deviating from its expected path over the Pacific Ocean.

Sydney is more than a travel detail in the show. Several characters’ backstories are tied to Australia, including Claire Littleton, who is returning homeward toward Los Angeles, and Jack Shephard, who is transporting his father’s body. The departure city helps explain why such a diverse group of passengers is traveling together.

Viewers sometimes confuse Sydney with the destination because the early story reveals the survivors’ circumstances gradually. The flight was leaving Sydney, not flying toward it; Los Angeles was the intended destination.
