Delta Air Lines is set to enhance the efficiency of its fleet by installing finlet modification packages from Vortex Control Technologies (VCT) on its Boeing 737-800 and 737-900ER aircraft. This initiative, announced on 17 June 2026, will see 240 aircraft equipped with the technology, following a comprehensive evaluation process between the two companies.
Finlets are aerodynamic devices that improve airflow, reduce drag, and enhance fuel efficiency by reshaping the airflow around the aft fuselage of an aircraft. This modification is expected to significantly lower fuel consumption and carbon emissions. "Equipping these Boeing 737-800 and 737-900ER fleets with Finlets represents a significant milestone for VCT," said Gil Morgan, CEO of Vortex Control Technologies.
The decision to implement finlets aligns with Delta's ongoing commitment to sustainability and operational efficiency. The airline's evaluation process included flight test validation, analysis of operational trends, and engineering reviews using computational fluid dynamics. Amelia DeLuca, Delta's Chief Sustainability Officer, emphasised the importance of such initiatives, stating, "We appreciate the strong partnership with VCT throughout the evaluation process and are looking forward to this implementation to further support our ongoing fleet efficiency initiatives."
With approximately 90% of Delta's carbon emissions stemming from jet fuel consumption, the adoption of finlets is a crucial step in reducing the airline's environmental impact. This move underscores Delta's dedication to sustainability and its pursuit of innovative solutions to enhance performance and reduce environmental impact
