airport to Heidmoor near Kaltenkirchen. Among the reasons cited were limited expansion possibilities, capacity constraints due to crossing runways, and noise. Lufthansa had introduced the Boeing 707 in 1960, which made more noise than previous piston-engined aircraft. The plans were dropped, owing both to bad experiences in other cities where airports had been moved far from city centres, and to Lufthansa's move to Frankfurt. In 1980 Northwest Orient started flights to Hamburg, originating from Minneapolis with a stop in London Gatwick. In 1981 they introduced a second flight from New York JFK via Copenhagen to Hamburg. All flights were operated with Boeing 747 aircraft. After Northwest Orient received traffic rights to serve Frankfurt they discontinued all flights to Hamburg from early 1985. In April 1985 Pan American World Airways started a daily non-stop flight from New York JFK to Hamburg, operated with Boeing 747. This was Pan Am's first non-stop service from the US to Hamburg. Starting February 1986 Pan Am also used their new long-range Airbus A310-200 on the route, which made it one of the first ETOPS routes across the Atlantic. In 1988 Japan Air Lines suspended their flights from Tokyo to Hamburg after serving the route for 24 years. One year later in 1989 Lufthansa suspended all flights between Hamburg and Tokyo after almost 30 years of service, which was the last route from Hamburg to the far east. In May 1989 American Airlines started a daily service from New York JFK via Brussels to Hamburg, and Delta Air Lines started a daily service from Atlanta via London Gatwick to Hamburg. American Airlines suspended their service after a year due to shortage of aircraft after the purchase of Eastern Air Lines' South America routes, Delta upgraded the Atlanta flight to a daily non-stop service with an extension to Berlin-Tegel from May 1991, and also served New York JFK – Hamburg from November 1991 after taking over Pan Am's North Atlantic route network. Development since the 1990s In March 1990 Lufthansa launched a daily flight from Hamburg to Newark and added another non-stop flight to Miami in 1992. This lasted for only one summer season and was then suspended together with the Newark flight in late 1992, which left Delta Air Lines alone in this market with their Atlanta and New York flights. From early 1993 to late 1994 South African Airways operated flights from Cape Town via
