I was on tail #692 FLL-ATL last Monday and the wifi sign was right on the fuselage at the side of the entrance hatch.

However, the NY based crew did not have a clue about it and when I asked if the aircraft was now equipped with power ports (which I doubted), I got blank looks. To one female FAs credit, she explored the seat areas very thoroughly looking for a port. She came up from searching on her knees with an apologetic look on her face and said "apparently there are none."

Since I had drained most of my battery in the FLL CRC with an intent to recharge it during a 2.5 hour layover in ATL, I did not try the service.
