The London to New York Air Route is an air route between London, UK, and New York, US. These two cities are connected by a heavily utilised 2999nmi air route which has been historically important to transatlantic aviation and is today served by several major airlines (British Airways, Virgin Atlantic, American Airlines, Delta Air Lines and JetBlue Airways: United Airlines flies out of the nearby airport of Newark, 9miles away from downtown Manhattan). The airports of Heathrow and JFK are the main international airports for the London metropolitan area and New York metropolitan area respectively, the world's two most important global cities. The route sustains the highest number of passenger seat kilometers per annum of any route globally (10.92 billion ASK's were scheduled in 2015). In 2018 British Airways achieved a revenue of $1.16 billion on this route alone, making their operation the highest value airline route globally. The route saw a total traffic figure in 2018 of 3,034,155 (+3.0% on 2017), the busiest of any transatlantic air route.
Prior to the aircraft's retirement British Airways operated a double daily supersonic Concorde service on the route which covered the distance in a scheduled time of 3 hours 15 minutes westbound and just under 3 hours eastbound.
