In compliance with standard procedures, Japan Air Lines retired the flight number 123 for their Haneda-Itami routes, changing it to Flight 121 and Flight 127 on September 1, 1985. While Boeing 747s were still used on the same route operating with the new flight numbers in the years following the crash, they were replaced by the Boeing 767 or Boeing 777 in the mid-1990s. Boeing 747-100SRs continued to serve JAL on domestic routes until their retirement in 2006, having been replaced by newer widebody aircraft such as the Boeing 747-400D and Boeing 777, introduced during the 1990s and early 2000's. Boeing 747 operations at JAL concluded in October 2011 when the last 747-400 was returned to the lessor as part of the airline’s efforts to cut costs.
