Only cell phones and electronic medical devices are allowed to be carried on; anything larger than a smartphone, including iPads, tablets, Kindles, children's video games such as a Nintendo DS, cameras and portable DVD players.
The new rule is expected to be announced by the Homeland Security Department on Tuesday, local time, and cover about a dozen foreign carriers.
Royal Jordanian flies to New York's John F. Kennedy International Airport, Chicago's O'Hare International Airport, as well Montreal and Detroit.
US-bound passengers have been banned from travelling with most electronic devices in their hand luggage on flights from several Middle Eastern and North African countries.
The ban, which seeks to bolster airline security, goes into effect on Tuesday for nonstop flights to the US from airlines based in Egypt, Jordan, Kuwait, Morocco, Quatar, Saudi Arabia, Turkey and the United Arab Emirates.
Royal Jordanian Airlines jumped the gun on Monday by advising passengers via Facebook that "carrying any electronic or electrical device on board in the flight cabins is strictly forbidden". It is also not clear why the electronic devices would be deemed a security risk in the cabin but not in the checked baggage hold.
The ban has no end date, officials said.
David Lapan, a spokesman of the Homeland Security Department, declined to comment.
A new travel ban on electronics from certain United States-bound flights is creating ripples with world travelers. While nothing has been confirmed by the TSA or DHS, an official announcement is likely to come Tuesday.
The carriers affected by the new policy are: Royal Jordanian, EgyptAir, Turkish Airlines, Saudi Arabia Airlines, Kuwait Airways, Royal Air Maroc, Qatar Airways, Emirates Air and Etihad Airways. The DHS said the procedures would "remain in place until the threat changes" and did not rule out expanding to other airports if circumstances changed.
