Delta Air Lines is moving forward with a plan to enhance the efficiency and performance of its fleet by installing Split Scimitar Winglets on its Boeing 737-800 and 737-900ER aircraft. The airline is working in partnership with Aviation Partners Boeing (APB) to implement this upgrade, which builds on the already widespread use of APB's Blended Winglets on several aircraft types.

Delta's fleet, which is among the largest globally, already features APB winglet products on Boeing 737-800, 737-900ER, 757-200, 757-300, and 767-300ER aircraft. The Blended Winglets, introduced in the early 2000s, are a common feature on modern jets and help reduce drag by minimizing wingtip vortices. This design has led to improved fuel efficiency and additional aircraft range.

Split Scimitar Winglets differ from the Blended design by including both upward and downward fins. This dual-blade approach weakens the vortex at the wingtip, resulting in further reductions in drag and improved fuel efficiency. According to the manufacturer, these enhancements can reduce fuel burn by 1.6% to 2.2% per aircraft, which translates to lower carbon emissions and operational savings for airlines.

Several major airlines have adopted Split Scimitar Winglets, including Ryanair, United Airlines, Qantas, and Aeromexico. United Airlines has implemented the winglets across its 737, 757, and 767 fleets to achieve around 2% fuel savings. Qantas is retrofitting its 737-800s with these winglets, expecting significant fuel savings and a reduction in operational costs. The retrofit program at Qantas is expected to continue through 2026 and will cover all 23 of its Boeing 737-800s.

Delta's decision to invest in Split Scimitar Winglets aligns with its broader sustainability goals. The airline has committed to achieving net-zero carbon emissions by 2050 and is taking several steps to reach this target. Initiatives include increasing the use of Sustainable Aviation Fuel (SAF), with a goal of replacing 10% of jet fuel with SAF by 2030. In 2024, Delta used over 13 million gallons of SAF. The company is also focused on operational fuel savings through enhanced routing, weight reduction, and optimizing auxiliary power units, as well as modernizing its fleet with more fuel-efficient aircraft like the Airbus A321neo and A220. Additional measures include introducing lightweight landing gear, electrifying ground equipment, reducing waste, exploring hydrogen-powered aircraft in partnership with Airbus, and participating in research projects such as the Boeing Sustainable Flight Demonstrator, which aims to cut fuel emissions by up to 30%.

The improved efficiency from these winglets supports Delta's ability to operate longer flights and reduces operating costs. These savings can potentially result in lower airfares for passengers. The airline also expects to lower per-passenger emissions and improve the onboard experience by reducing the effects of jet streams and air vortices.

Aviation Partners Boeing commented on the partnership, stating it "couldn't be more excited" to work with Delta and that the airline's commitment to sustainability complements the benefits provided by Split Scimitar Winglets. The upgrade is expected to deliver cost savings and support Delta's environmental objectives.
