What is a significant wing design difference between the Boeing 737 and 787?

The significant wing design difference between the Boeing 737 and the Boeing 787 is that the 787 features raked wingtips. This design choice is integral to enhancing the aerodynamic performance of the aircraft. Raked wingtips are angled back in a way that improves fuel efficiency by reducing drag, which results in better overall performance during flight.

In contrast, the 737's wing design, which incorporates straight wingtips, does not provide the same aerodynamic advantages as the raked design on the 787. The differences in wing design reflect the advancements in technology and aerodynamics that have been applied in the development of newer aircraft models like the 787. The materials used in the wings of the 787 also contribute to its efficiency, but the raked wingtips specifically play a crucial role in optimizing its aerodynamic characteristics.
