If you travel, you have to spend time at the airport. Either you are through security a bit early or your connections allow for some time to wander an airport in another city.

People watching. Airports are great for this. You see people from all over the world in various states of consciousness and moods. You see joyful reunions and tearful departures. You see anger and frustration in between hangovers and mourners.
Wifi. The use of laptops and smart phones is rampant and a good way to pass the time. Hopefully you are not paying for it.
Free Magazines. It may be to launch a new product, get more readers or just deal with excess copies, but many times you can find stand alone racks of free magazine and newspapers in some airports.
TV. Many airports have tv screens. It may not be handy for most seats or it may not be something you want to watch but it's there.
Playgrounds. Many airports have play areas for the kids. They are usually a bit more dirty and well-used than I would like. Make sure you enforce a policy of hand washing or hand sanitizers.
Shopping. If you want to pay extra for all kinds of things, you can do it at airports. From clothes to massages to medical services.

Drinking. Coffee is better than alcohol. At least if you are on my flight. Drinking and flying don't mix well. It may even make a certain percentage of people mentally off balance at high altitude, yet airlines and airports like to promote it and make money from it.

Pray. If you are religious, you can probably find a chapel at most airports. You can pray for family and friends. You can pray for yourself. You can pray that your flight lands safely and on time.
