This question has been a moving target since March, but the Department of Homeland Security announced a new policy for electronics entering the US.  As of June 28th, all airlines with inbound flights to the US are required to implement stricter measures for screening carry-on and checked baggage as well as vetting passengers before they board.  If they don’t meet the new standards, they are subject to the laptop ban currently in place for nine airlines from eight countries, or even have their airline certificate revoked disallowing entry into the US.

What does this mean to you as the traveler?  You should allow more time to go through security at international airports (3 hours) as airports and airlines work through the new procedures.  Be prepared to see more bomb-sniffing dogs, have your laptop or tablet checked by an agent and see new scanner equipment.
