Bloody dreadful decision. Just got off flight from jburg and flights around southern Africa. The idea of having to listen to people jabbering on their phones is a nightmare. Upper deck will no longer be the haven of piece. It was bad enough with the face timers and skypers in the airport lounge.
In the past, it has been the obnoxious (insecure) folk who compete to be the first to make the call as you disembark. Yes, Mr Sad, you are SOOOO important as is your "deal". BTW, how is your Mum!!!!!
If it was that dangerous would people really be allowed to self police turning their phones off???
I asked a garage a while back about why phones were not allowed when filling petrol. The answer was not the hi tech one I expected. It was if you dropped it, it migh cause a spark that could cause ignition.
