Greetings from JFK.
I'm at Terminal 8 and just spent time on a fully empty A321T taking pictures. I'll update more shortly but here are some pictures and a link to my detailed article on the plane.

A321T at JFK
NEW YORK — Going against a “bigger is better” trend, American Airlines announced plans to replace its three-class Boeing 767-200 aircraft, which it primarily uses on its transcontinental flights from New York’s John F. Kennedy Airport to San Francisco and Los Angeles, with new, but much smaller, Airbus A321 jets.
American took delivery of its first A321T on November 21, 2013 in Hamburg, Germany. The aircraft, with registration N101NN, left Hamburg that day and arrived in Dallas shortly before sundown.
American will put the new A321T into service just three weeks from now with nonstop service from New York to Los Angeles. American will put three A321Ts into service on January 7… <SNIP>
