The 787 is different, and Boeing engineered it so passengers could fly 16 hours and still feel (relatively) refreshed.

The Boeing 787 Dreamliner is a long-range marvel, with its flight duration capability varying by specific model and configuration. The most popular variant, the 787-9, has a standard flight range of approximately 7,500 to 8,000 nautical miles, which translates to roughly 17 to 18 hours of nonstop flying time depending on wind and weight. As of 2026, Qantas operates one of the longest Dreamliner routes from Perth to London, which takes about 17.5 hours. The slightly smaller 787-8 can fly for a similar duration, while the largest version, the 787-10, is built for higher capacity and has a shorter range of about 6,400 nautical miles (around 14 hours). However, the aircraft is technically certified for even longer endurance; during "Project Sunrise" test flights and delivery ferries, Dreamliners have remained airborne for over 20 hours with reduced passenger loads and extra fuel reserves.
