The longest flight in the world, currently flown by Singapore Airlines, is proof. For travelers who want to visit loved ones—not to mention frequent fliers looking for new ways to earn and burn miles and points—this 19-hour journey from John F. Kennedy is a gem in the crown of ultra-long-haul travel.

As of early 2026, the title for the world's longest non-stop commercial flight is held by Singapore Airlines. The airline operates a direct route between Singapore Changi Airport (SIN) and New York's John F. Kennedy International Airport (JFK). This marathon journey covers a distance of approximately 9,537 miles (15,348 kilometers) and typically takes between 18 hours and 45 minutes to 19 hours, depending on wind conditions. To make such a long flight viable, Singapore Airlines uses the Airbus A350-900ULR (Ultra Long Range), which is configured in a premium-heavy layout featuring only Business Class and Premium Economy seats, as there is no standard Economy cabin on this specific aircraft. While Qantas is currently testing and finalizing its "Project Sunrise" flights—which aim to connect Sydney directly to London and New York with flight times exceeding 20 hours—the Singapore to New York route remains the reigning champion of endurance in scheduled commercial aviation. This flight is a marvel of modern engineering, requiring specialized fuel tanks and enhanced crew rest facilities to ensure safety and comfort over such a massive duration.
