This will be easy to implement on Etihad flights from AUHsince all US bound flights leave from the same area AFTER going thru secondary screening as well as US customs & immigration. HOWEVER, This is going to be a nightmare for EK. flights to the US leave from all 3 concourses with no special security checks ........if they implement secondary security for all US flights the delays will be enormous. The other problem is EK is a huge carrier for business people traveling from the US to the Gulf, India, etc. if they can't use their laptops it's gonna be a big problem
