Ugh, not looking forward to this. So many issues...not being able to work on the plane, not having IFE, small children that can't be entertained for 12 hours (mine included...), having to check bags again...
Luckily for me I only head overseas a few times a year, but if I get caught up in this, my solution will be this. Have my overseas office have a loaner laptop waiting, put all my stuff on an SSD / USB and just use the loaner there. I hate to leave my ipad at home (tablets confiscation is just stupid), but I guess I'll be renting Apple store movies on my tiny iphone from now on to stay "carry on only".
Let's just completely shut down all air travel...that would mitigate the risk, eh?
