About the Boeing 757-300

The Boeing 757-300 is the stretched variant of Boeing's remarkably versatile narrowbody twinjet, extending the fuselage by 23 feet over the baseline 757-200 to accommodate up to 289 passengers in high-density configurations. Launched in 1996 and entering service with Condor in 1999, the -300 was Boeing's answer to airline demand for more capacity on thin long-haul routes without requiring widebody economics. Only 55 were built before production ended in 2004, making it the rarest member of the 757 family and one of the least common Boeing jetliners still in regular service.

The type shares the original 757's exceptional performance characteristics: powerful Rolls-Royce RB211 or Pratt & Whitney PW2000 series engines give it hot-and-high capability that few narrowbodies can match, while its supercritical wing design enables a maximum operating speed of Mach 0.86 and efficient cruise at FL410. The 757-300's range of approximately 3,400 nautical miles is shorter than the -200's due to the added weight and drag, but still sufficient for transatlantic sectors like New York to Western Europe. Pilots prize the type for its handling qualities and powerful thrust-to-weight ratio, which provides confident performance on short runways and steep approaches.

The cockpit is nearly identical to the 757-200 and shares a common type rating with the 767, a cost-saving feature that made both types popular with airlines operating mixed fleets. Today the 757-300 flies primarily for U.S. legacy carriers on high-density domestic trunk routes where its unique combination of capacity, range, and airport performance remains unmatched by newer narrowbodies.
