Correct.
Someone asked me last week why the 762s did not have winglets installed. I believe the 763s over at American, Hawaiian, Delta, etc are getting them, but I haven't heard of any plan for the 762s.
Any plan to fit the 762 fleet would require a separate flight test program to certify winglets on just the 762 fleet (i.e. The flight testing done on the 763s does not carry over for certification on the 762s). Same issue with the 752 and 753 fleets as each fleet had to conduct separate flight test programs.
It will be interesting to see what we do with the UAL 752 fleet. CAL is fairly big on the fuel savings that the winglets offer (roughly 5%) and I suspect that if the UAL 752 fleet is destined to stay around any length of time, outfitting that fleet with the winglets will happen.
