On an AA flight from SFO to JFK in business class today. On the flight out, my MacBook charger (the white square kind that the prongs flip out of) kept falling out of the loose outlet because of the weight. I’ve had this issue before. Figured I would just buy a 2-foot extension cord so my power cord could lay on the tray for my return. Halfway through the flight a flight attendant literally started yelling at me that I was in violation of FAA regulations for using an extension cord of a flight (I only had one thing plugged in to it), and that I would immediately be ticketed if an FAA agent was on the flight. Was forced to unplug. Is this real, or was she misinterpreting something? I could see a concern if I had multiple things in the plug, but it was literally just my laptop cord, w the extension cord as a go between.
