The Boeing 727 is a midsized, narrow-body three-engined jet aircraft built by Boeing Commercial Airplanes from the early 1960s to 1984. It can carry 149 to 189 passengers and later models can fly up to 2,700 nautical miles (5,000 km) nonstop. Intended for short and medium-length flights, the 727 can use relatively short runways at smaller airports. It has three Pratt & Whitney JT8D engines below the T-tail, one on each side of the rear fuselage with a center engine that connects through an S-duct to an inlet at the base of the fin. The 727 is Boeing's only trijet aircraft. The 727 followed the 707, a quad-jet airliner, with which it shares its upper fuselage cross-section and cockpit design. The 727-100 first flew in February 1963 and entered service with Eastern Air Lines in February 1964; the stretched 727-200 flew in July 1967 and entered service with Northeast Airlines that December. The 727 became a mainstay of airlines' domestic route networks and was also used on short- and medium-range international routes. Passenger, freighter, and convertible versions of the 727 were built.

Historical:  The Alaska Airlines fleet consists of all Boeing 737 aircraft including four freighter jets. A regional fleet of Alaska branded Embraer 175 jets are operated by the wholly-owned subsidiary, Horizon Air, and third-party contractor, SkyWest Airlines.

Since the 1960s, Alaska has consistently operated Boeing jet aircraft in its fleet. The first jetliner type operated by the airline was the Convair 880. Alaska also operated the Convair 990 jetliner. Besides the current Boeing 737 models and other various aircraft flown by Alaska, the airline operated the three-engine Boeing 727-100 and 727-200. The last 727 was retired in May 1994.
