I had heard these frames were purchased only to subsidize lift for frames that were out of service for the cockpit retrofit. Knowing UPS probably to reduce available used 76's to Amazon and Fed Ex. Thoughts?

Winglets only become efficient at or near max range. If they plan on operating aircraft domestically on shorter flights, this costs fuel due to the extra weight of the winglets.
