Hi folks,
I am wondering why they didn't use winglets on the aircraft anymore? (777, 737NG, A3XX, 747-500/-600)
Do you guys have an answer for me?
Thanks a lot!

Winglets add complexity to the wing, while the same result can be achieved by a simple wing extension, or by a raked wingtip such as on the 767-400.

One of the advantages of a winglet over a wing extension is that a winglet allows the wingspan to be shorter, and fit in a smaller parking place. Because of the large wingspan, Boeing offered a folding wing on the 777-200 that would make the wingspan shorter and allow the aircraft to fit in a smaller parking place. Nobody ordered it.
