Who invented this absurd 332 rumor - a pilot??
No one fies the 332 more than about 5000nm in scheduled service and US will never fly that aircraft to China from PHL. PHL-TLV will be about it. It's ludicrous to compare the 332 with the 777-200ER, there is a 20K+ engine thrust difference, a maximum takeoff weight difference of at least 150K lbs and a 1000nm range difference - all in favor of the 772 . Forget about the Airbus web site number of 6400nm - that is in still (zero velocity) air. In order for a 332 to make PHL-PEK, it would need to be SIGNIFICANTLY weight restricted in both passengers and cargo, since a full fuel load would be required for the range. Doing so would likely make the route economically infeasible - if it would even get polar certification.
