That is if you chose to fly with layovers.  This is probably going to be more common when flying, to have layovers.  That way the planes will pick up more passengers in already croweded planes.  What do you when you have a layover?  Shop?  Use the laptop?  Sleep?  Read?

For myself, I have the urge to use the computer and read.  Well, most of my layovers have been an hour or two long so, so I go on the laptop and read.
