I've gotten lost at JFK Airport more times than I care to admit. But Bing Maps now offers full maps of airports so you make it to your flight without getting turned around.
They only have 43 US airports listed right now, but that number is sure to grow. It just better hit phones soon. I just can't see myself running around with a paper printout as opposed to popping out my phone the next time I'm in Miami International. And that airport sucks. [Ubergizmo]
