An interesting point about the Boeing 737-300 which was once considered to be one of the most fuel efficient aircraft flying. Bmibaby and Jet2 among others are still flying the type today and both airlines can still be considered successful even if the type is no longer considered to be the most fuel efficient. Some airlines have retrofit the type with winglets and more fuel efficient engines to boost their efficiency savings. On another note, would buying a newer generation of the type not cost more in the long run because of the initial start-up costs of purchasing or leasing the aircraft?
