Heathrow, Gatwick, Stansted and City are all fairly quiet airports with boarding announcements typically limited just to the immediate vicinity of a gate. Luton seems to have several automated broadcasts for each flight covering areas well away from a gate... meaning passengers hear a LOT of announcements. Is there a reason why LTN feels the need to broadcast so many announcements ? Is there anywhere in the departures area which is a quiet zone - ie "no announcements" ?
