Boeing’s clean-sheet cycle: next large airliner could be ~30 years after the 787
Leeham analysis finds Boeing’s cycle between brand‑new, clean‑sheet large‑airliner designs is roughly 30 years: the 787 was announced in December 2003 (formal launch spring 2004) with a May 2008 entry‑into‑service target. That cadence suggests a new Boeing clean‑sheet large airliner may not appear until the 2030s.
