New York Times:

Australia announced on Friday that it had moved the search area for Malaysia Airlines Flight 370 nearly 700 miles to the northeast, the latest in a long series of changes by the authorities on where they think the plane might have disappeared...

The new zone is 1,150 miles west-southwest of Perth, Australia, closer to Perth than the previous zone, shortening the flight for surveillance aircraft by up to an hour in each direction and allowing aircrews to spend more time actually looking for debris from Flight 370.

It has now been three weeks since the jet disappeared.
