What Is an Ultra-Long-Haul Flight?

Ultra-long-haul (ULH) flights are typically defined as non-stop journeys longer than 14–16 hours, covering more than 8,500 miles. These routes are powered by cutting-edge aircraft like the Airbus A350-900ULR and Boeing 787-9 Dreamliner, which offer better fuel efficiency, quieter cabins, and improved air quality—key for reducing passenger fatigue on marathon journeys.

The Future of Long-Haul Travel

Looking ahead, Qantas’ Project Sunrise is expected to launch record-breaking routes by 2027, including Sydney–London (10,573 miles) and Sydney–New York (9,950 miles). These 20+ hour flights will use specially designed Airbus A350-1000s and offer wellness-focused features like circadian lighting, meditation zones, and rehydration menus.

Other carriers such as Turkish Airlines and Emirates are also planning direct intercontinental routes, signaling a boom in ultra-long-haul demand.
