It wasn't Ezy it was Flybe and the aircraft was a Dash 8 400 series.
The drunk man certainly wasn't violent but he was fiddling with his mobile phone during the flight and at times it was not off as it should have been.
This was a concern because it has been said many times that mobile phones can interfere with aircraft systems. That is part of the safety briefing at the start of the flight.
On the other hand I suppose it could have been one with a flight safe mode for certain functions.
But it did bleep as if text messages were being received.
I do have another question about this flight but I'll put it on the passengers and slf forum.
