Found this tidbit on the NRA-ILA site:
Special Advisory for New York and New Jersey Airports: Despite federal law that protects travelers, authorities at JFK, La Guardia, Newark and Albany airports have been known to enforce state and local firearms laws against airline travelers who are merely passing through the jurisdiction. In some cases, even persons traveling in full compliance with federal law have been arrested or threatened with arrest. As noted above in the section entitled "Federal Law on the Transportation of Firearms," FOPA`s protections have been substantially narrowed by court decisions, and persons traveling with firearms may want to avoid New York and New Jersey or make arrangements to ship their firearms to their destination, rather than bringing them through these jurisdictions.
