I wish I knew as well. I live in the US and fly pretty regularly. My only gripe with the automated check-in machines is that I wish they had separate lines for attended and un-attended machines. I have no problem walking up to the machines and checking in all by myself, but what I see every time I go to the airport is a row of 15 machines, half of which are occupied one person staring blankly at the screen, while their traveling companion attempts to flag down one of the three people working the counter. It's maddening, but I can tell by observation that the author is not alone.
