New thread new possibilities for the book/movie
Pilot gets rid of copilot shortly after sign off and bails out. Girlfriend picks him up as he passes back over the island. They create new Identities and live happily ever after
Real soon, maybe in the next couple of hours searchers will find the floating debris and it will most likely be tsunami debris, wreckage of a different nature or a large stack of wooden pallets that probably fell off a cargo ship.

That is not that far-fetched. He clearly did not want to have the plane traced by radar or the wreckage found.
He could have programmed the plane to fly south until fuel ran out, dropped/slowed down over the Cocos, bailed out to be picked up by the person he last spoke with on the phone while the plane flew on for several hours and crashed.
Hopefully the Aussies have screened all flights out of the Cocos from day one.
