British Airways has updated its guidance on broken or "uncharged" electronic devices, and now says customers can have them posted to an address of their choosing in order to fly.
Previously, BA had warned that customers found in possession of a device that would not turn on would be forced to miss their flight.
The airline now says that passengers can rebook if they wish to carry the device in their hand luggage, or have it either posted or ready to collect on their return.
The Government is "constantly" reviewing new leads to potential security threats to the UK, the Transport Minister told Good Morning Britain.
Patrick McLoughlin tried to reassure the public the Government was doing everything it could to keep air passengers safe after it asked anyone flying to or from the UK to keep their mobile phones switched on through security checks.
However, the Conservative minister refused to say what the security threat was "we don't go into the exact details of the information we've received."
All air passengers flying into or out of UK airports have been advised to make sure electronic devices in their hand luggage are charged before they travel.
The updated guidance has been issued by the Department for Transport "in line with the US advice".
A DfT spokesman said, "Passengers flying into or out of the UK are therefore advised to make sure electronic devices being carried in their hand luggage are charged before they travel."
British Airways passengers who attempt to board a plane to the United States with an uncharged electronic device will not be allowed to fly, the airline has announced.
The measure follows new rules enforced in the US which stated that mobile phones, laptops, tablets and other devices without power would not be allowed onto flights in hand luggage.
In response, new British government guidelines say devices that do not switch on would not be allowed on to aircraft bound for the States.
Meanwhile British Airways has taken the extra step of telling customers that customers who bring broken or uncharged devices will have to re-book.
Uncharged phones and laptops will be barred from planes going to the US under new security measures, the US Transportation Security Administration (TSA) said.
The new rules come amid growing concern about the increased capability of al-Qaeda affiliates in Yemen and Syria, and the threat the foreign fighters of Syria pose to the home countries.
Officials in the US say some passengers at overseas airports will be asked to turn on their phones under new security measures.
The Transportation Security Administration (TSA) said it will require some foreign airports to order passengers to turn on devices such as mobile phones. Any that do not power up will not be allowed on flights to the US, and those travellers may have to undergo additional screening.
