Here's a link to a page from which you can get the Google Earth view of flights in and out of LAX, BOS, ORD, ATL, or JFK:

If you don't already have Google Earth running, it should open when you click one of the airport links.
It also has links to a few relevant overlays, like airspace restrictions and sectional charts.
Enjoy.
