How do winglets on a plane help the plane?

Answer:

Winglets descrease induced drag (drag from the production of lift) created by wing-tip vortices, simply turbulent airflow off the edge of the wing. So they do increase handling characteristics and fuel efficiency because of the increase in lift and decrease in drag.

Hope this helped!
