American is flying its premium-configured Airbus A321Ts between New York JFK and Boston. Most of its flights between the two airports through January 4 are operated by this plane.
The American Airlines Airbus A321T is a 3-cabin aircraft with economy (including Main Cabin Extra extra legroom seating), fully flat business class, and 1-1 seating first class. It’s the most luxurious, high-end narrow body aircraft and the best plane flying domestically in the U.S. (and I include the Qantas Boeing 747 that flies Los Angeles – New York JFK in that assessment).
Anyone can book available business class seats on the plane for free (even as they charge for extra legroom coach seats)!
