If you search the popular travel bargin site Kayak.com for a one-way non-stop ticket from Sydney to LAX on September 22nd, 2010 and you’ll get an Oceanic Airlines flight as a result.
For those of you who don’t follow the television show Lost, Oceanic Airlines is the fictional airline which crashed Oceanic Flight 815 on a mysterious island. The flight was traveling from Sydney to Los Angeles, which under mysterious circumstances, on September 22, 2004, the airliner, carrying 324 passengers, deviated from its original course and disappeared over the Pacific Ocean.
Of course, the whole thing is just a fun easter egg for Lost fans. When you try to purchase the flight, it redirects you to the Lostpedia article on Oceanic Flight 815. Arya Ponto points out on Twitter that the price is made up of the numbers.
