Laptops and tablets on U.S.-bound flights from Mexico will be subjected to heightened

Laptops and tablets on U.S.-bound flights from Mexico will be subjected to heightened carry-on security measures beginning Wednesday at the request of the U.S. Department of Homeland Security, Mexican authorities announced.

Mexico's Transportation Department said in a statement that the measures apply to "electronics larger than a cellphone."

The department recommended that passengers travel with as few of those devices as possible in carry-on bags. It did not give details on the checks other to say they will take place separately from baggage, without cases or covers.

Same changes for flights from Canada to the US. They are now recommending an arrival time of 2 hrs prior to departure to allow for the additional screening.

May be an inconvenience for some but better to be safe than sorry.
