Those that don't have winglets have structural issues that prevented the winglet mod from being installed. The mod was not just a simple swap out the wing tip sort of deal. There was a lot of internal wing mod work that need to be installed to add strength to the spars and stringers of the wing. Existing repairs to these structures, or the wing skins made a few aircraft ineligible for the mod.

I may have missed a few, but these are the ones still in the fleet (some are parked due to COVID but many are still active).
