Delta Air Lines and Aviation Partners Boeing (APB) have partnered to reduce aircraft carbon emissions. APB has also announced the carrier’s (Delta’s) recent agreements to purchase Split Scimitar Winglets for its 737-800 fleet and for several recently acquired 737-900ER aircraft, says an official release. The carrier also gave a green nod for Scimitar Blended Winglets for up to 70 of Delta’s 757-200 aircraft. Both the Split Scimitar Winglets and Scimitar Blended Winglets are upgrades to APB’s ubiquitous Blended Winglets. Delta has previously purchased and installed APB winglet products on its 737-800, 737-900ER, 757-200, 757-300, and 767-300ER fleets. “APB is proud that Delta has, once again, turned to APB’s winglet products across its fleets to deliver savings in jet fuel consumption and gains in fuel efficiency,” adds the release.
