About the Boeing 767-300

The Boeing 767-300 is the stretched variant of Boeing's pioneering widebody twinjet, introduced in 1986 as the world's first twin-engine aircraft certified for extended-range overwater operations under ETOPS rules. Stretching the fuselage by 21 feet over the baseline 767-200, the -300 became the backbone of long-haul fleets for carriers seeking fuel efficiency and operational flexibility on medium-density routes where the 747 was too large. With seating for 218 to 269 passengers in typical two-class layouts, it bridged the gap between narrowbody workhorses and jumbo jets, opening new city pairs that couldn't sustain four-engine economics.

The type's reliability and range (up to 5,990 nautical miles in the -300ER configuration) made it a favorite for transatlantic and transpacific services throughout the 1990s and 2000s. Its cockpit commonality with the 757 allowed airlines to cross-train crews, reducing operating costs. While passenger variants have largely retired from major carriers in favor of the 787 and A350, the 767-300 found a lucrative second life as a freighter.

FedEx and UPS operate large fleets of factory-built 767-300Fs and passenger-to-freighter conversions, valuing the type's cargo capacity, range, and ability to operate from shorter runways than larger freighters. The aircraft cruises at Mach 0.80 with a service ceiling of 43,100 feet and a maximum operating speed of 360 knots or Mach 0.86. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
