Take care of business 1st. Use the restroom, get something to eat and create a "home base" near your flight gate.

Look at the airport map to see if there are any child play areas or exhibits that you could visit.

Take a walk around the airport. Create a guided treasure hunt for your children. Let’s find the water fountain, the news stand, the rest room, etc.

For toddlers, create a mini-play area away from high traffic areas. Pick a place that has natural boundaries with chairs or windows so the child can wander "freely" but somewhat contained. Windows are great for observing air-traffic. Play eye-spy.

Some airports have exposed outlets that can be used to recharge DVD players.
