As of 2026, the Boeing 777-200LR (Longer Range) remains the production aircraft with the longest range in Boeing's history, capable of flying up to 8,555 nautical miles (15,843 km) non-stop. This "Worldliner" was specifically designed to connect almost any two cities on Earth, such as New York to Singapore or London to Sydney. However, the title is currently transitioning to the Boeing 777-9 (777X), which is entering widespread service in 2026 and offers a range of approximately 7,285 nautical miles with a much larger passenger capacity. While the Boeing 787-9 Dreamliner is also a "range king" (capable of 7,565 nautical miles), the 777-200LR still holds the crown for absolute distance without refueling. These ultra-long-haul jets allow airlines like United and Singapore Airlines to operate "trunk routes" that bypass traditional hubs, saving passengers hours of travel time on transoceanic journeys.
