Boeing's 777X, a new widebody aircraft currently under development, is expected to have a significant impact on long-haul aviation. The aircraft has faced multiple delays since its launch in 2013 and first test flight in 2020. Industry observers now expect the first delivery to take place in 2027. The two main variants are the 777-8, with a range of 8,745 nautical miles (16,196 km), and the 777-9, which can fly up to 7,285 nautical miles (13,492 km).
The following are some of the longest routes that the Boeing 777X could potentially serve once it enters commercial operation:
Sydney to New York (8,646 nautical miles/16,012 km) is one of the most anticipated ultra-long-haul routes. Qantas has targeted this city pair as part of its Project Sunrise initiative but chose the Airbus A350-1000 over the 777X due to its earlier availability and operational reliability. "Qantas expects to receive its first A350 in 2026." Currently, Qantas operates Sydney–New York flights using a Boeing 787-9 Dreamliner with a stopover in Auckland.
