USATODAY.com - Is this old bird about to get its wings clipped?: "But airlines don't like the 747's fuel bills. It burns about 3,200 gallons of fuel per flight hour, about one-third more than the Boeing 777, says Eclat Consulting of Vienna, Va. Air carriers also have a hard time finding 400-plus paying passengers to fill flights. As a result, the four-engine, double-deck 747 has lost favor to a new generation of smaller, more versatile, twin-engine planes that save airlines money. Boeing's own cheaper-to-fly 777 is part of the reason for the squeeze on the aging behemoth."
