Boeing787-10 Dreamliner

The Boeing 787-10 is the biggest Dreamliner. It stretches the 787-9 by another 5.5 meters to seat roughly 40 more passengers, giving it the lowest seat-mile cost in the family. In exchange it gives up some range — it is built for dense, high-demand medium-haul routes rather than the thin ultra-long-haul markets that suit the -9. Think busy transcontinental and regional intercontinental legs where every seat gets filled.

History

Boeing launched the 787-10 in 2013 and flew the first aircraft on March 31, 2017. It entered service with Singapore Airlines in April 2018, four years after the 787-9. Because the -10 shares the same wing, engines, and systems as the shorter Dreamliners, it reached the market quickly and with minimal new certification work.

Unlike the -8 and -9, the 787-10 is assembled only at Boeing’s North Charleston, South Carolina site — its longest one-piece composite fuselage barrels are too large to ship efficiently to the Everett line.

The Family

The Dreamliner comes in three lengths sharing the same wing, systems, and type rating:

Variant	Length	Seats (typical)	Range
787-8	56.7 m	248	~13,530 km
787-9	62.8 m	296	~14,140 km
787-10	68.3 m	336	~11,910 km

The -10 is the longest but shortest-legged of the three. A common type rating lets pilots move between all three with minimal extra training, so airlines mix them across a network based on route demand rather than crew cost.

Same Wing, Different Mission

The 787-10 keeps the -9’s wing and maximum takeoff weight roughly the same while carrying more structure and passengers. That is the deliberate trade: the extra fuselage weight eats into range, so the -10 tops out near 11,910 km (6,430 nmi) instead of the -9’s 14,140 km. But on routes it can reach, it moves those passengers at the lowest fuel burn per seat of any widebody Boeing builds — around 25% better than the older jets it replaces.

Because the airframe is about 50% carbon-fiber-reinforced polymer, the -10 inherits every Dreamliner passenger comfort feature: higher cabin pressure (6,000 ft equivalent), higher humidity, larger electronically-dimmed windows, and a fuselage of one-piece composite barrels with almost no external rivets.

In Service Today

The 787-10 is operated by carriers running dense long- and medium-haul networks, including Singapore Airlines, United Airlines, Etihad Airways, KLM, and EVA Air. Airlines often deploy it on high-frequency routes between major hubs — for example intra-Asia trunk routes or transatlantic legs — where its capacity edge matters more than outright range.

Spotting Tips

• Length: The -10 is the longest 787 at 68.3 m — noticeably more stretched than the -9, with an extra pair of doors
• Raked wingtips: Like all 787s, the wingtips taper to a sharp swept point with no separate winglet, unlike the 737 or A320
• Noise-reducing chevrons: The engine nacelles have the same distinctive sawtooth (chevron) trailing edge as the rest of the family
• vs the 777: The 787-10 approaches the older 777-200 in length but is a slimmer twin with the Dreamliner’s smooth four-panel windscreen and no eyebrow windows
