Terms of the settlement were not disclosed when the agreement was announced in federal court in New York. Cantor Fitzgerald had sought nearly $1.1 billion in damages above insurance payments. The New York Times reported that the firm later reduced its demand to between $400 million and $500 million. The case had been scheduled for trial in January.
In 2001, Cantor Fitzgerald's headquarters were in the top floors of the north tower, which was struck by American Airlines Flight 11. The firm accused American of negligence in allowing hijackers to board the plane and crash it into the tower. American responded that it could not have predicted such an attack and that it followed federal security regulations.
A spokesman for American, Sean Collins, said Friday that the airline's insurers had agreed to settle the claims but the airline did not admit liability.
"American Airlines and the courageous crew members and passengers on Flight 77 and Flight 11 were all victims of the terrorist attacks of Sept. 11, 2001," Collins said in an emailed statement. He said American defended itself against claims by property owners and others who believe that "American should have done what the government could not do prevent the terrorist attacks."
Through a spokesman, Cantor Fitzgerald declined to comment.
