Well Done Lufthansa!!
At least there'll be one airline that will allow a peaceful cabin for all travellers - well at least mobile phone free!!
If the practise of permitting the use of the confounded things becomes widespread, then I for one will ensure that I travel with a "no mobiles" airline - and I'm sure there will be many others who will do the same.
I'm old enough to remember life before the mobile phone, and from a business perspective I'm not sure that it has made companies 1% more efficient or better managed as a result of their invention.
