The first Boeing Co. 747-8 jumbo jet to carry paying passengers completed its maiden commercial flight Friday.
The German carrier last month celebrated the delivery of Boeing’s new 747-8 at a ceremony at Paine Field in Everett, where Boeing has assembled 747s for more than 45 years.
This latest version is the jet maker’s largest. The Intercontinental was stretched 18.3 feet over its predecessor, the 747-400, to allow for another 51 passengers, or a total of 362 in Lufthansa’s three-class configuration. With new engines and updated technology, the 747-8 saves operators roughly 13 percent in fuel costs over the 747-400, Boeing says.
