What are the enhanced security measures for flights to USA, Canada and UK?

All those travelling to USA, Canada and the UK are required to switch on their electronic devices at the Dubai International airport or risk being denied access to fly. Please ensure that your electronic devices have sufficient power before reaching the airport. This is part of enhanced security measures required by the authorities of these countries.

All hand baggage is subject to screening. Screening will be done at relevant boarding gates, for flights departing to destinations in the US, UK and Canada. 

Passengers who are unable to switch on their electronic devices risk being offloaded or being asked to leave behind such devices. There is no secure location to store these devices, and Emirates will be unable to bear responsibility for these items.
