Nickmo,
Some loco have gone for kiosk solutions - try EZY at EMA, it is 100% kiosk and they have several airports where kiosks are available.
Most locos are going the internet check-in solution rather than airport kiosks. They see this as the futureand it is cheaper for them.
I do find it interesting that in aviation a lot of people (passengers) indicate that not having 'a human' to interact with represents poor service yet, these same people probably make journeys by train, underground, busses or other transit system and do so happily without the human interface. Why do people think that aviation should be different to other forms of transport?
