Sharklets!

A320 CS-TNS during the turn-around in Sal (Cape Verde). This chartered flight from Porto and back was my first chance to experience one of TAP's few Sharklet retrofitted A320's. Besides increasing fuel efficency by reducing wing tip vortice induced drag, the Sharklets also make the airplane look a whole lot better which, I guess, is always a commercial advantage. The C-17 in the back also has wingtip extentions which serve the same purpose. Those are, however, called winglets instead of Sharklets which is an Airbus trademark.
