While transiting through Lima's Jorge Chavez International Airport on Monday (9/3), I saw that LAB operates a 727-200 with winglets on its flight from La Paz.

I know that the new Pan Am also operates the type with winglets and am wondering what other carriers do as well. What's the purpose? If its to improve fuel efficiency, then why don't we see winglets on more 727s?

The winglets are part of a package designed to transform the B727's into Super 727's. They were developed to improve fuel efficency. B727's that get the winglets also get new engines so it is expensive for airlines to buy them and only if you plan to operate the B727 for a long time, you buy the package.

In Mexico Aviacsa is testing the winglets on one of its B722's. The airliner is HK3 with new engines and is used primarily on the MEX-MTY-LAS route.

Hi:

These improves for the older 727 is a good option specially for a small and poor airlines like LAB in Boliviaor Aviacsa in Mexico. Of course these improves is a benefit for the cargo airlines.

You do not have to re-engine the 727 to put winglets on. Dugan sells kits for the winglet and flap droop mod. Use the same old JT8-7 to 17.

The company offering the winglet modification you mentioned is Dugan Air Technologies http://www.quietwing.com/. According to Dugan "The idea behind the Quiet Wing System is to increase aircraft operating performance, provide significant economical payback while complying with Stage 3 noise regulations without the added weight and fuel burn."

Other competing stage 3 hush kits modification packages are offered by BF Goodrich http://www.super27.com/, FedEx and Raisbeck http://www.raisbeck.com/s2.html

Aviacsa is not that "small and poor". With 20+ jets it's way larger than LAB, Ecuatoriana,Ladeco,etc. even when there are at least three carriers in Mexico larger tnat Aviacsa.
Back to the topic. Here's XA-SLM at LAS.

The first 727 I ever saw with winglets was of Royal Airlines back in the mid-90's:
