American is unlikely to serve JFK/ORD/PHL/CLT in 2015 I suspect
On the contrary.
PHL will stay A332 due to cargo alone.
JFK will stay as good connection bank down the eastern seaboard with good O&D to New York (AA210/211 had average load factor of 92% in summer with a fair few days booked out).
CLT will stay due to good connections to the mid west states, and strongly hinted it will rotate with MIA in the winter/CLT in the summer.
ORD will stay as it has some O&D as well as strong connections to the west coast. Again a good performer, with the fact it has run continuously for over 25 years and one of just 4 winter ORD-Europe routes a testament to this.
