SINGAPORE -- When the world's longest nonstop flight takes off here on Thursday, it will carry Singapore Airlines' hopes for reviving a route that failed once amid rising crude oil prices and faces the same challenge today.
This time, Singapore's flag carrier counts on an ultralong-range version of the fuel-efficient Airbus A350-900 jet to cut fuel costs, and also on steady demand from business travelers willing to pay more for a direct flight with luxury amenities.
