Emirates and Turkish airlines exempted from US laptop ban

Emirates and Turkish Airways say they have been exempted from a US ban on laptops in airline cabins, joining Etihad in satisfying American security concerns that had cut into the long-haul carriers' business.

It remains unclear how the airlines addressed fears that Islamic State or other groups might smuggle explosives on board in electronic devices, but in Turkey, authorities now use CT scanners to take cross-section images of passengers' electronics just before they board planes heading to the US.
