Royal Jordanian Airlines told passengers that medical devices were still allowed.
Ahead of an expected official announcement today, the Department of Homeland Security on Monday put out a statement saying it had "no comment on potential security precautions, but will provide any update as appropriate".
Seeking to bolster airline security, the USA government is temporarily barring passengers on certain flights originating in eight other countries from bringing laptops, iPads, cameras and most other electronics in carry-on luggage starting Tuesday.
What started late Monday with cryptic social media posts by Royal Jordanian Airlines - since deleted - has turned out to be true this morning.
Most major airports in the United States have a computer tomography or CT scanner for checked baggage, which creates a detailed picture of a bag's contents. The countries affected are Jordan, Egypt, Turkey, Saudi Arabia, Morocco, the UAE, Qatar, and Kuwait. Federal officials have just announced a new ban on large electronics coming into the US from eight Middle Eastern countries.
Both of South Florida's major worldwide airports are expected to have flights affected by an electronics ban.
American officials declined to comment publicly on the matter, but anonymous sources confirmed to NBC News that plans were in place to limit the use of electronics on certain flights. Officials said the airports were selected based on the "current threat picture".
The airline said that laptops, tablets, DVD players and electronic games must be checked with baggage.
Passengers on those certain flights flying out of a specific list of airports in the Middle East and elsewhere will be banned from taking certain electronics on board the plane.
Just another careful, well-executed policy implementation involving airports and the Middle East from the Trump administration.
Officials said that they believe a threat to the US would be negated if a passenger transferred through a secondary city with additional and more trustworthy screening procedures.
A spokesman for the International Air Transport Association, which represents international carriers including Royal Jordanian, said they were not informed of the new restrictions and were working to get additional information from USA authorities. No word yet if flight crews will be able to use their devices either.
