Malaysia Airlines Records Monthly Profit for First Time in Years: Report

The disappearance of MH370 is a "heavy burden," the CEO said.

Despite a multi-year, multi-million dollar search, investigators have yet to uncover MH370, the Boeing 777 en route from Kuala Lumpur to Beijing carrying 239 people that deviated from its flight path and vanished, likely into the Indian Ocean. It's a mystery that isn't helping the company's bottom line -- or the entire aviation industry, according to Mueller.

"A forever missing aircraft is certainly a heavy burden for the industry as a whole," Mueller told the AP.

The airline is a "ship that has many leaks," Mueller acknowledged to the AP, adding that the February profit "tells us that we are on the right trajectory."

Malaysia Airlines hopes to be back in the black by 2018, according to the AP.

The airline did not immediately respond to a request by ABC News today for additional comment.
