The Boeing 787 Dreamliner does not have traditional vertical winglets because it utilizes a more advanced aerodynamic feature called raked wingtips. Unlike the vertical "fences" seen on a Boeing 737 or Airbus A350, raked wingtips are integrated extensions of the wing itself that curve backward and slightly upward. This design is specialized for long-haul aircraft to reduce lift-induced drag more effectively than vertical winglets in a "high-aspect-ratio" wing environment. By spreading the wingtip vortices (spiraling air) over a larger area, the raked tips improve fuel efficiency and takeoff performance while weighing significantly less than bulky bolt-on winglets. Furthermore, the 787's wings are made of advanced carbon-fiber composites, which allow them to flex significantly during flight—up to 25 feet at the tips. This flexibility, combined with the raked design, acts like a natural shock absorber, providing a much smoother ride for passengers by "damping" the effects of turbulence, a key selling point of the 787 in 2026.
