The UK and US have decided to ban some electronic devices from cabin baggage on some airlines and from some countries on inbound flights The ban includes: laptops; e-readers; tablets; dvd players; and smartphones over a certain size - though why smaller smartphones are exempt is a bit of a mystery.
All of the airlines are State carriers from Moslem countries, as well as UK carriers to those countries when returning.
Another mystery is Why? and Why now?
Something is going on and we are not being told what it is. If I was due to be going to any of the countries concerned I would be hitting the "Cancel" button, at least until a clear indication for the new rules was given.
