A blended wing body (BWB) aircraft is a design that merges the fuselage and wings into a single, smooth, aerodynamic structure. Unlike traditional aircraft, which have a distinct cylindrical fuselage and separate wings, BWB aircraft integrate these components, creating a more streamlined shape that offers several performance benefits.

But more than that, JetZero says BWB designs can help reduce emissions by up to 50 percent, while keeping the same engine technology and fueling infrastructure. By reducing drag,

Delta Air Lines announced on March 6, 2025, that it is partnering with JetZero, a US startup that is developing a clean-sheet blended-wing-body (BWB) airliner for 250 passengers.

Delta Air Lines and JetZero are partnering to develop a commercial blended-wing-body (BWB) aircraft that would be 50 percent more fuel efficient than those in current operation, the carrier has announced.
