Insurers for American Airlines, United Airlines and other aviation defendants have agreed to pay US$95 million to settle claims that security lapses led planes to be hijacked in the September 11 attacks.
The settlement was described in papers filed Tuesday in Manhattan federal court.
Developers of the new World Trade Center buildings had once demanded US$3.5 billion from aviation-related companies after hijacked planes destroyed three skyscrapers among five demolished buildings on September 11, 2001.
Lawyers said the agreement signed last week resulted from "extensive, arms-length negotiations" by lawyers "who worked diligently for months."
The agreement also said the parties make no admissions or concessions with respect to liability for the attacks.
