Delta Air Lines and JetZero Collaborate on Fuel-Efficient Blended-Wing Aircraft

The innovative design aims to cut fuel consumption by 50 percent and could begin commercial operations by 2030.

Delta Air Lines has partnered with JetZero to develop a blended-wing-body (BWB) aircraft designed to reduce emissions and fuel costs.
The aircraft, known as the Z4, is expected to be 50 percent more fuel-efficient than traditional tube-and-wing designs.
The design features a lightweight frame, reduced drag, and engines mounted on the roof for quieter operation, while accommodating over 250 passengers.
Delta will provide operational expertise and contribute to cabin design, with plans for increased overhead bin space, accessible seating, and improved boarding efficiency.
The Z4 is projected to take its first flight in 2027, with a goal of achieving commercial availability by 2030, aligning with Delta's net-zero emissions target for 2050.
