What to do when are stuck in a airport all night?
This is what I have been doing: Messaging people, talking to old friends, listening to country music, watching the planes land/departure, walking around with no shoes, meeting other people who are also stuck overnight, checking the clock only to find out that it have been only 5 minutes since I last saw it and of course on the Internet. Fortunately for me I have a mobile Internet card that work pretty well, you always have the option to pay for wifi, which by the way, I think it should be free. I mean, you get wifi for free almost everywhere, yet they wanna charge you to use on every single airport in the U.S.

The first thing I did was to locate a nice corner, with a power source near me, that way I am able to charge my iPod and other  electronic devices. I got lucky and found a nice place behind the departure monitors. If you stay on the middle, you probably won’t be able to sleep at all, people will be passing by all night and the cleaning machines noise will pretty much make your night a living hell  (yes, they clean the floor and others at night). 
The airport security personnel more likely will provide you with a pillow and a blanket when they see you laying down on the floor, if not then just ask for one, they have tons of those on every airport I have been at. 
If you are by yourself, make sure you go to the bathroom before you get comfortable, if you do so after, then you will have to pick up everything and take it with you, after 9-11, if you let any baggage unattended you can be sure that you will find security next to it when you return and probably a k-9 messing up all your stuff. 
Don’t get stupid, you are stuck already, so try to sleep and set up your alarm so that you don’t miss the next flight in the morning.

Good luck.
