Australian flag-carrier Qantas Airways has ordered four new Boeing [NYSE: BA] Next-Generation 737-800 airplanes to join its initial 737-800 fleet of 15. The four new twinjets, due for delivery between May and July of next year, are worth approximately $US240 million at list prices. First deliveries of the Qantas 737-800s were achieved only 100 days after contract signature. "We have been very pleased with the integration of the Boeing 737-800 into our fleet," said Qantas Executive General Manager of Aircraft Operations, David Forsythe. "It has been one of the smoothest introductions of a new type, undoubtedly helped by high levels of commonality with our existing Boeing 737s."
