changed from Newark International Airport to Newark Liberty International Airport in 2002. This name was chosen over the initial proposal, Liberty International Airport at Newark, and pays tribute to the victims of the September 11 attacks and to the landmark Statue of Liberty, lying east of the airport. In October 2015, Singapore Airlines announced intentions to resume direct nonstop service between Newark and its main hub at Singapore Changi Airport, which had ended in November 2013. The airline announced that service would resume some time in 2018, and the Airbus A350-900ULR was chosen as the aircraft for the route. On May 30, 2018, Singapore Airlines officially announced that nonstop service between Newark and Singapore would begin on October 11, 2018, and Newark Liberty once again became host to what was then the world's longest non-stop flight. Continental Airlines (now merged with United Airlines) began flying from Newark to Beijing-Capital on June 15, 2005, and to Delhi on November 1, 2005. The airline soon started flights to Mumbai. On July 16, 2007, Continental announced it would seek government approval for nonstop flights between Newark and Shanghai-Pudong in 2009. Continental began flights to Shanghai from Newark on March 25, 2009, using a Boeing 777-200ER aircraft. Newark was the only New York area airport used by Philippine Airlines (PAL), until financial problems in the late 1990s caused it to terminate this service. In June 2008, flight caps were put in place to restrict the number of flights to 81 per hour. The flight caps, in effect until 2009, were intended to be a short-term solution to Newark's congestion. After the cap expired, the FAA embarked on a seven-year-long project to reduce congestion in all three New York area airports and the surrounding flight paths. Newark is a major hub for United Airlines (Continental Airlines before the 2010–12 merger). United has its Global Gateway at Terminal C, having completed a major expansion project that included a new, third concourse and a new Federal Inspection Services facility. With its Newark hub, United has the most service of any airline in the New York area. On March 6, 2014, United opened a new , $25 million hangar on a parcel to accommodate their wide-body aircraft during maintenance. In 2015, the airline announced plans to leave JFK altogether and streamline its transcontinental operations at Newark. On July 7, 2016, the United States Department of Transportation announced that
