Not suggesting that it's the routine, but going by the current speculation that the crew might have taken a "shortcut".
Such speculation is supported on the basis of the wreckage location (directly in line to UPG) and timing -- at just 11 minutes after takeoff. The aircraft likely headed on a southerly direction almost immediately after takeoff.
But the shortcut speculation seems incorrect on the basis of the wreckage altitude (only 7,000 ft), unless maybe they intended to hug the coast until they can fly direct to Makassar, but then turned early.
