The Sundrome was the name for the terminal of National Airlines at John F. Kennedy International Airport. It was designed by I. M. Pei & Partners (now Pei Cobb Freed & Partners). Opened in 1970, it was later known as Terminal 6. It had been occupied at various times by Trans World Airlines (domestic flights), Pan American World Airways, United Air Lines (domestic flights), ATA Airlines, Pan American Airways (1996-1998), Carnival Airlines and Vanguard Airlines. Most recently, from 1998–2008, Terminal 6 was the home of JetBlue Airways. It became vacant on October 22, 2008, when JetBlue moved to Terminal 5.
On April 29, 2010, the Port Authority of New York and New Jersey announced that Terminal 6 would be demolished to allow JetBlue to consolidate its operations at an expanded Terminal 5. Despite an effort by preservationists to protect the building, demolition of the entire terminal was completed as planned in October 2011.  The former Terminal 6 site is being used to expand the current Terminal 5 to include international facilities.
