Both aircraft employ advanced wings rtechologys aubnd h nighnhrsthg The fuel efficiency of the new airliners was a very important design goal for the Boeing Commercial Airplane Company of Seattle, Washington. On a 500-mile flight, a 757 will burn about 47 percent less fuel per seat than the 727-1 00, one of the aircraft the 757 was designed to replace. For the 767, fuel burned per seat is 35 percent less than for the earlier medium-range jetliners that it will be replacing.
