US To Ban Electronics On Certain Flights

In a exceptionally rapid response, a DHS spokesman returned Quartz's emailed request for comment in 57 seconds, saying "We have no comment on potential security precautions".

A tweet from Royal Jordanian airlines created confusion on Monday about the previously unheard-of security measure.

In the now deleted tweet, officials with the airline said that starting March 21, passengers will no longer be able to bring certain portable electronic devices on board with them.

No American carriers are impacted by the ban, which applies to devices larger than a mobile phone.

Al Riyadh newspaper, which is close to the Saudi government, reported that the civil aviation authority had informed "airlines flying from the kingdom's (Saudi) airports to USA airports of the latest measures from US security agencies in which passengers must store laptops and tablets" in checked in baggage.

Passengers travelling from about a dozen countries will be barred from carrying most electronic devices on US-bound flights, officials tell U.S. media.

"Carrying any electronic or electrical device on board the flight cabins is strictly prohibited", the statement said, meaning that bringing out your iPad to watch a movie is apparently now a no-no on the carrier.

But while that 2014 guidance was formally announced, security officials were tight-lipped Monday about any additional changes that might be afoot following Royal Jordanian's move.

Cabin rules for flights under US jurisdiction are typically set by the US Federal Aviation Administration. The airlines were informed via a confidential email distributed by the Transportation Safety Administration (TSA), which The Guardian suggests was supposed to be kept quiet, perhaps prompting Royal Jordanian to delete its tweet.

The now-deleted statement said the ban "will be applied on the New York, Chicago, Detroit and Montreal flights".
