"Effective August 4, 2017, Royal Jordanian passengers are allowed to carry these electronic devices in the cabin," the airline said in a statement referring to large phones, laptops and tablets.
The United States instituted the laptop ban in March for eight North African and Middle East countries based on intelligence that the Islamic State group was working to build a bomb into a tablet or laptop.
Britain followed suit and banned similar-sized electronics from being carried into cabins on direct flights from six countries -- Turkey, Jordan, Egypt, Lebanon, Saudi Arabia and Tunisia.
In early July, Royal Jordanian said the US laptop ban had been lifted for all of its US-bound flights.
Both Washington and London had said the ban would be lifted for airlines that implement new safety measures.
