So out of curiosity, what is to stop a pax in CE moving up to row 1 if they see a vacant seat after the doors have closed? It might have been blocked for pre-selection prior to boarding.....but after boarding is complete?
The evil stare I give silvers who try it. Not knowing their place in the world - outrageous! I am also told silvers smell - not the kind of people you want sitting next to you!
