Cairo International Airport is one of four airports that remain under a ban for carry-on laptops on US-bound flights, after Washington removed six of the original ten airports from its ban on 11 July.
The security measures, which affected airports in the Middle East and north Africa, were introduced in March after intelligence suggested that Islamic State was developing a bomb concealed in personal electronic devices.
Subsequently the US department of homeland security mandated 180 international carriers operating US-bound flights to improve their security procedures, including the installation of explosive-detecting scanners and additional bomb-sniffing dogs.
In addition to Cairo, the ban remains in place for Saudi Arabia's two main international airports, in Riyadh and Jeddah, and Morocco's Casablanca Mohammed V International Airport.
The six airports removed from the ban include Abu Dhabi (Etihad Airways flights to US), Doha (Qatar Airways), Dubai (Emirates Air), Istanbul (Turkish Airways), Kuwait (Kuwait Airways), and Amman (Royal Jordanian), meaning passengers on US-bound flights can once again carry laptops in hand luggage.
