Many, many years ago I was a 'traffic agent', but over the years titles change, a good example would be , 'Duty Officer', in my day that was a senior position, but I suspect that it isn't now?
I'm also aware that T+C's have changed somewhat, but if you're young and want to bounce out of bed in the morning looking for some fun (I still have some very fond memories of Scandinavian Hosties!), then there isn't a better job in the world.
