Are you planning to fly south of the border anytime soon?

The United States Transportation Security Administration said travellers to the U.S. may be asked to power up their mobile phones and other electronic devices before they board their flights as part of a new security measure.

The new regulations follow reports that terrorist groups are working on the use of typical consumer electronic gadgets as explosive devices. Jeh Johnson, secretary of U.S. Homeland Security, directed the TSA to implement the enhanced measures at certain overseas airports with direct flights to the U.S.

“As the travelling public knows, all electronic devices are screened by security officers,” a statement from the TSA said. “During the security examinations, officers may also ask that owners power up some devices, including cell phones.’

“Powerless devices will not be permitted onboard the aircraft. The traveler may also undergo additional screening,” the statement warned.

The TSA did not disclose the overseas airports where the enhanced screening is being conducted.

About two months ago Transport Canada relaxed it restriction on the use of mobile devices onboard flights. Previously, passengers were required to turn off their mobile devices during takeoff and landing.

In May this year, the transportation regulars said passengers airline passengers would now be allowed to use their mobile devices during the flight as well as on takeoff and landing.
