Someone mentioned, I think here at FR, that Malay Air flew over the war zone to save gas. They are in or close to bankruptcy, so chose the shortest route in spite of the dangers. The regular route would have cost them more for fuel.
Lawsuits from MH370 are pushing them toward or HAVE pushed them into bankruptcy. Now they’ll be out of business forever.
Maybe he was 'uncomfortable' saving the company money?
This is also the consensus on a respected commercial pilots forum.
Total fuel savings for taking the “war zone route?” $1500.
