Don't know if you have seen the winglets being installed by several operators.

Oh yeah! Love the winglets on the 757. Makes a beautiful bird even better looking.

Who do you fly for? And what aircraft?

I fly the 757 and 767.

Is that at KEGE, Eagle, CO by chance?? If not where is it please? The Dallas Mavericks 757 has them as well.

Location was in San Jose, Costa Rica. Howdy Lynn!

Well I was kinda close, maybe west coast. We are to go there someday the boss says.....

I love'em, they make me feel safer.

On a serious note, how effective are they at reducing the vibrations of the wing structure?... I mean photographically, so as not to get out of topic

They aren't used to reduce vibration(there really isn't any to start with), but they are used to reduce induced drag in cruise to the tune of about 3-5% in fuel savings.
