Boeing 747

Responding to requests from Japanese airlines, Boeing developed the 747-100SR as a "short range" variant of the 747-100. The SR has a lower fuel capacity but can carry more passengers, up to 498 in early versions and more than 550 in later models, because of increased economy class seating. The 747SR has a modified body structure to accommodate the added stress accumulated from a greater number of takeoffs and landings. The -100SR entered service with Japan Airlines (then Japan Air Lines) on 7 October 1973. Specifically, the SR has extra structural support at the wings, fuselage, and the landing gear along with a 20% reduction in fuel capacity. Later, short range versions of the -100B and the -300 were also developed. The SRs are used primarily on domestic flights in Japan.

Two 747-100B/SRs were delivered to Japan Airlines (JAL) with a stretched upper deck to accommodate more passengers. This modification is known as the "SUD" (stretched upper deck).

All Nippon Airways (ANA) operated 747SRs on domestic Japanese routes with 455 or 456 seats but retired the last aircraft on 10 March 2006. JAL operated the 747-100B/SR/SUD variant with 563 seats on domestic routes, and retired these planes in the third quarter of 2006. JAL and JALways have operated the -300SRs on domestic leisure routes and to other parts of Asia.
