@flights.spotter: As of June 2026, the Boeing 777X program is in low-rate production but remains in certification testing, with first customer deliveries now expected in 2027 rather than the original 2020 target. Boeing has already built dozens of 777-9 aircraft, including test aircraft and early production frames, many of which are stored at Everett awaiting certification and retrofit work. Industry reports indicate more than 30 aircraft have been assembled, with change incorporation expected to take years. #boeing #b777x #b7779 #b777 #aviation
