The Boeing 737-300, 737-400 and 737-500 are the so-called 'Classic'-versions of the 737. They are much improved successors of the earlier 737-200. The three Classic versions seat 100 to 171 passengers and although they are out of production since the year 2000, many of them are still flying with airlines.

Boeing 737 SouthwestIn the early 1980s Boeing started the development of a stretched version of the 737, the 737-300. As power source Boeing chose the modern CFM56 high-bypass turbofan, produced by CFM International, a joint venture of General Electric (USA) and SNECMA (France). However, this engine has a fan with a larger diameter than the Pratt & Whitney JT8D of the 737-100 and 737-200 had, and when fitted under the wing, there would not be enough ground clearance. The Boeing engineers therefore put the engine in a higher position ahead of the wing, flattened the underside of the inlet and extended the nosewheel leg. The new engines made the aircraft much more fuel efficient and less noisy than its predecessors. Boeing also improved the aerodynamic characteristics and applied cockpit and cabin features developed for the 757 and 767.

The 737-300 typically seats 126 to 149 passengers. It took off for its maiden flight on 24 February 1984 and Boeing delivered the first 737-300s to US Air and Southwest Airlines in December 1984.

Boeing 737 KLMIn 1985 Boeing decided to stretch the 737-300 fuselage by a further 3.30 m (10 ft) for another new version, the 737-400, which seats up to 168 passengers. Other changes included more powerful engines, a strengthened wing and a stronger landing gear. The 737-400 flew for the first time on 19 February 1988 and the first production aircraft was delivered to launch customer Piedmont Airlines in September of the same year. Because the 737-400 has maximum commonality with the 737-300, pilots qualified for one model, do not need a new type-rating to fly the other version. The same applies to the later 737-500. Some 737-400s have been converted into freighter or combi aircraft. Alaska Airlines was the first airline to have some of its aircraft converted for these roles.

Boeing 737 ContinentalThe 737-500 is the shortest model of the three Classic variants. It has a fuselage only 25 cm (10 in) longer than that of the 737-200 and seats up to 132 passengers. Boeing presented this version as the ideal 737-200 replacement. The 737-500 was launched in May 1987 with a 38-aircraft order from Southwest Airlines and it made its maiden flight on 30 June 1989. Boeing delivered the first aircraft to Southwest in March 1990. The 737-500 offers more range than the 737-300 and that makes it suitable for longer routes with a relatively small passenger market.

The 'Classics' remained in production until the third 737 breed, the Boeing 737 'Next Generation', appeared: the 737-600, 737-700, 737-800 and 737-900. Boeing built a total of 1988 Classics: 1.113 737-300s, 486 737-400s and 389 737-500s. The final aircraft, a 737-400, was delivered to CSA Czech Airlines in the year 2000. Early in 2015, about half of all 737 Classics built are still in airline service. Many of them are fitted with winglets to improve fuel efficiency.
