No need to talk to anyone
And you like this??
I am French, and not sure that French (or Italian, Spanish, etc) passengers will appreciate this kind of travelling without talking to anyone!
it works maybe in AMS with "nordic" minds, but not with "mediterranean" ones, and I should add fortunately for us, passenger service agents!
I've been told that SAS had tryed a few years ago in Oslo, this system of self-boarding, and stopped it after a few practices due to big security problems on board (passengers canceled on board, passengers not checked on board, etc ...)
