Air passengers flying between the U.S. and Europe may soon have to go without large electronic devices, as a ban on such devices already in effect for several Middle East and North African airports dramatically expands.

The U.S. Department of Homeland Security is considering banning electronics larger than a cellphone on all transatlantic flights, according to a report by CBS News on Monday, and a decision is expected soon, ahead of the busy summer travel season. The Guardian reported last month that such a ban was under consideration.

Aviation expert Alex Macheras tweeted news similar to CBS’s report Monday, saying the ban would likely take effect “in a few weeks.”

That could severely disrupt travel plans on both sides of the Atlantic, impacting everyone from business travelers hoping to get work done on their laptop to vacationers trying to watch a movie on their iPad.

The news division of CBS Corp. US:CBS reported that the ban has been discussed for more than a year, and that the government has been meeting with airlines to weigh the security measures against their impact on passengers.

“We have not made any decisions on expanding the electronics ban,” the Department of Homeland Security said in a statement. “However, we are continuously assessing security directives based on intelligence and will make changes when necessary to keep travelers safe.”

Requiring laptops and tablets to be checked with luggage could also cause safety concerns, with a larger number potentially dangerous lithium-ion batteries having to be stored in the cargo hold.

The current ban on large electronic devices was announced March 21, and affects nine foreign airlines flying nonstop to the U.S. from 10 airports in the Middle East and North Africa. It requires all laptops, tablet computers, DVD players and cameras to be stowed in checked luggage. Passengers may carry on smartphones. The U.K. soon instituted a similar ban.

At the time, intelligence officials said they were worried about the possibility of terrorists smuggling explosives onto planes in large electronic devices, such as a laptop bomb that almost took down a Somalian passenger plane last year.

In response, some Middle Eastern airlines started renting tablets to passengers. But the ban, along with the threat of a potential travel ban by the Trump administration, has taken an economic toll as well. Last month, Emirates Airlines, the world’s largest carrier by international traffic, cut back flights to five U.S. cities, citing lower bookings.
