Many UPS 767 Freighters have winglets, but maybe these were PAX before conversion.

Odd to me that UPS don't have ramp-space issues with their 763F''s with winglets then.
I think another reason is that Fed Ex will only use their 763F's domestically ( MD-10F replacements) and not on long-haul routes where the extra range would come in.

The drag trumps the savings below a certain distance. I could be wrong I am not an engineer but I remember reading this. Also ramp space. The LAN 767's they are leasing do have winglets.
