The [[McDonnell Douglas MD-11]] was the first aircraft with split-tip winglets in 1990.

For the [[737 Next Generation]], third-party vendor [[Aviation Partners]] has introduced a similar design to the 737 MAX wingtip device known as the split scimitar winglet,<ref>{{cite web | url=http://www.aviationpartnersboeing.com/products_737_800_3.php | title=737-800-3 | work=Aviation Partners Boeing }}</ref> with [[United Airlines]] as the launch customer.<ref>{{cite press release | url= http://newsroom.united.com/2013-07-17-United-Airlines-is-First-to-Install-Split-Scimitar-Winglets | title= United is first to install Split Scimitar winglets |publisher= United Airlines | date=July 17, 2013}}</ref>

The [[Boeing 737 MAX]] uses a new type of wingtip device.<ref>{{cite web |url=http://www.nycaviation.com/2012/05/boeing-says-radical-new-winglets-on-737-max-will-save-more-fuel/ |title=Boeing Says Radical New Winglets on 737 MAX Will Save More Fuel |author= Matt Molnar  |date=2 May 2012  |work=NYCAviation }}</ref>  Resembling a three-way hybrid of a winglet, wingtip fence, and raked wingtip, Boeing claims that this new design should deliver an additional 1.5% improvement in fuel economy over the 10-12% improvement already expected from the 737 MAX.
