I am about to take an Air France flight in a couple days, and I received this in an e-mail from AF:
Important: New security measures for travel to the USA and Canada:
From now on, all electronic devices you plan to carry on board or in your hand baggage (phones, tablets, computers, e-readers, video game consoles, cameras, video cameras, etc.) must be charged and in working condition. You must present these items at boarding. At security checkpoints, we are required to refuse boarding to any passenger carrying a device that is not properly charged or not in working condition.
We recommend you keep all chargers for your devices in your hand baggage. Outlets are available in the boarding hall. We also recommend that you arrive early at the airport.
This is the first I've heard of this and, according to the answers on this question from 2 1/2 months ago, it seems like this was not the case, at least not then.
Can anyone provide some source/reference for these "security measures" being referred too? Has anyone experienced this personally? Do they actually make you log into your notebook and phone etc.? I would rather put them in the checked baggage, then.
