The Boeing 777’s future is ultimately a two-track story. Legacy 777-300ERs will gradually transition into secondary roles, while the Boeing 777X family ultimately assumes the mantle. Boeing has gradually phased out Boeing 777-300ER production, with records showing only a single passenger delivery in 2024, which ultimately marked the end of the production line. Several Boeing 777-300ERs will continue to fly throughout the decade, with more airframes eventually migrating to being torn down and feeding robust spare parts markets. Boeing 777X service entries remain delayed, and both Boeing and its airline customers are now guiding to the first Boeing 777-9 services taking place in 2026.
