Well lets see...I am arriving in JFK on a Wednesday at 11am on an American Eagle flight from DC. It is all one ticket and I've been told that my bags will be checked through to Tokyo (assuming the plane isn't late). My flight to Tokyo on JL leaves from terminal 1 at 1:05 pm.

Are the Airtrains well marked? I reeeally don't want to end up on the wrong one headed into NYC! I am slightly intimidated by the idea of getting through JFK.
