This is surely coming. Really the only question is when. Check the news - this ban is the product of the juicy intelligence news that Tump was bragging about with the Russians last week. The ban was supposed to have already gone into effect several days ago - Delta Airlines even had signs printed up to that effect and had started posting them - but apparently the ban was held up temporarily due to pushback from the airlines and travel industry. But as sure as the sun will rise, you can expect it's coming. Look to the existing ban on flights from MIddle East countries for what to expect - basically, any device with a battery that's bigger than a cell phone. iPads, cameras, game consoles, anything that's powered. It appears the ban will only be on flights from Europe to the USA, but of course that makes no sense (for many reasons) so it could easily be expanded in response to the justifiable criticism that will follow. Personally, I expect that the ban will be expanded to all flights, including domestic flights within the US. As a historical note, I believe the current ban on liquids started out on just some flights, and was later expanded to all (that the TSA controls).
As an avid photographer who loves to travel, this kills me, but I'm quite sure it's coming.
I'm not sure how to respond (behaviorally...I know exactly how to respond politically and and rhetorically...). Am exploring options to buy some dedicated, externally-armored, internally-padded hard cases for checking camera gear and iPads, but those scream "steal me!" so they would need to go inside some ordinary, beat-up looking baggage to limit attention. Of course, it's all stillat risk of both theft and damage, so I also need to find some insurance policy that covers these goodies (most insurance has exclusions or laughably low limits on what they'll cover for electronics).
Business travel, which relies on laptops, is going to take a huge hit. This is going to change travel profoundly, and will lead to airlines going bankrupt. Oy. I'm going to go have a drink...
