Google Maps, Round II: A few unadvertised features I missed the first time around!

You can put in any three-letter airport code, and it will pop up a map of the airport, such as Reagan National. And then with that map, of course, you can zoom, local search and all the rest of it.

I stand corrected! To top it off, for us GPS users, you can actually put in coordinates and pull up a map: 38.9,-77.0. And of course, if you can use coordinates to find a map, you can use them to get directions, too: DC to Chicago. Wow!

So now, all they need to do is add the coordinate search ability to Search by Number, the address search ability to Street Maps, and an airport map link to Travel Information.
