Emirates and Turkish Airways said Wednesday they have been exempted from a US ban on laptops in airplane cabins, joining Abu Dhabi-based Etihad in satisfying American security concerns that had cut into the long-haul carriers' business. It remains unclear how the airlines addressed fears that ISIS or other groups might smuggle explosives on board in electronic devices, the AP reports. But in Turkey, authorities now use CT scanners to take cross-section images of passengers' electronics just before they board airplanes heading to the US. The Department of Homeland Security, which oversees airplane safety in the United States, did not immediately respond to a request for comment early Wednesday.
On Wednesday, Dubai-based Emirates said in a statement that it had worked to "implement heightened security measures and protocols" to satisfy American requirements. It did not elaborate, following a similar precedent set by Etihad, which American officials cleared on Sunday. In Istanbul, Turkish Airlines tweeted that passengers aboard its US-bound flights should "fasten your seatbelts and enjoy your own electronic devices." The US laptop ban, first announced in March as a security measure, now applies to nonstop US bound flights from seven international airports in Amman, Jordan; Kuwait City; Cairo; Jeddah and Riyadh, Saudi Arabia; Casablanca, Morocco; and Doha, Qatar.
