Everyone has probably heard of the myth of someone placing a phone
call using their mobile phone to only find out that an adverse outcome occurred during it. There have been stories where interference caused a plane to veer of course due to a phone call. Hence why they are asked to be shut off during flights. British Airways announced that they will allow limited use on mobile phones such as texting and data usage. Business-class-only flights from London City airport to New York’s JFK have been allowed to use their devices. British Airways is testing this out and may implement voice calls further down the road based on feedback from customers. Still, there might be some safety concerns with even allowing limited use.
