The US and UK authorities are banning electrical items larger than smartphones from cabin baggage on flights from certain countries in the Middle East, North Africa, and Turkey.
The move is being introduced as an anti-terrorist precaution. Announced on March 21, the US ban covers inbound flights on nine airlines operating out of ten airports.
The UK ban, announced hours after the US move, is essentially similar but applies to different airlines.
The British Government has decreed that passengers on 14 airlines would not be able to carry laptops in cabin luggage on inbound direct flights from Turkey, Lebanon, Jordan, Egypt, Tunisia and Saudi Arabia.
Large electronic devices will still be allowed on board in checked baggage.
Canada’s Transport Minister, Marc Garneau, has said his country is also considering restrictions on electronics in passenger aircraft cabins.
The airlines included in the US move have been given a deadline of 07:00 GMT on Saturday to impose the ban. So far, the restriction has no end date.
The UK decision states that phones, laptops and tablets larger than 16.0cm x 9.3cm x 1.5cm will not be allowed in the cabin on flights to the UK from Egypt, Jordan, Lebanon, Saudi Arabia, Tunisia and Turkey.
