Recently we travelled Dubai to Rome with Emirants.Prior to taking off the Flight Attendant told a passenger in the seat in front to turn off mobile phone and as soon as she moved on and we were taking off he was on the phone again - phone on speaker ( whats app ) so he and his partner could talk to kids - this went on on and on for most of the journey as he rang and spoke to different people - he only stopped when food came. Airlines need to have rules in place - when phone can be used and how.in one way we were luck only 5 hour flight and not a evening flight - the guy was in the middle of three seats and pity the person next to him
