Saarinen died of a brain tumor in 1961, a year before the romantic structure was completed. Seven years after its completion, a new departure-arrival concourse and lounge were added to the terminal. This, however, did not help the financial deterioration the terminal slowly began to experience. When first designed, JFK International Airport envisioned having different terminals for different airline companies. The idea was more successful on paper than when brought to life, and the terminal was shut down in 2001.
