Those statements do not contradict each other. The cruise portion of a flight is the most efficient, but usually the longest portion by a long shot. It can still use the most fuel despite being the most efficient. Driving a Prius from Chicago to LA will still use more fuel than driving a pickup from your garage to Wal-Mart, for example.
