The world's longest commercial flight, a 19-hour journey from Singapore to New York, took off Thursday from Changi Airport.
The Singapore Airlines Airbus A350-900ULR will touch down at Newark Liberty International Airport early Friday after traveling 15,350 kilometers.
Singapore Airlines previously flew the same route, but abandoned it in 2013 due to high oil prices and the gas-guzzling four-engine aircraft used.
Singapore Airlines is offering no coach seats, instead stocking the plane with 67 business-class spots and 94 premium economy. Shortly before takeoff, premium economy tickets were going for more than $2,100.
The Airbus A350-900ULR ('Ultra Long Range') is a new two-engine plane with far greater range and fuel capacity than other commercial airliners. In addition, it has several features that aid passenger comfort during the trip, like hospital-grade air filters, improved pressurization and humidity, and customizable lighting that eases the transition between time zones.
Singapore Airlines says it plans to add several flights from Singapore to Los Angeles in November, bringing the total number of weekly flights to the United States to 53.
