The 787-8 Dreamliner can fly 242 passengers up to 7,350 nautical miles (13,620 km) in a typical two-class configuration. The 787-9, a stretch of the 787-8, can fly 290 passengers 7,635 nautical miles (14,140 km) in addition to more cargo, allowing airlines the ability to grow routes first opened by the 787-8.

The Boeing 787 Dreamliner's range depends on the specific variant, but it is one of the world's most capable long-haul aircraft. The 787-8 has a range of approximately 7,305 nautical miles (13,530 km), while the most popular variant, the 787-9, can fly even further—up to 7,565 nautical miles (14,010 km). This allows for massive non-stop routes, such as London to Perth or New York to Tokyo. The largest variant, the 787-10, trades some range for increased passenger capacity, flying about 6,330 nautical miles (11,730 km). In early 2026, Boeing introduced a "High MTOW" (Maximum Takeoff Weight) upgrade for the 787-9 and -10, which adds roughly 400 miles (643 km) of additional range or allows for extra cargo. Because the Dreamliner is made of lightweight composite materials rather than aluminum, it is more fuel-efficient and can maintain higher cabin humidity, making these ultra-long-haul flights much more comfortable for passengers. These range capabilities have enabled the "Point-to-Point" revolution, allowing airlines to fly directly between smaller cities without requiring a stop at a massive hub like Dubai or London Heathrow.
