Ultra long-haul flights have redefined global air travel, enabling passengers to traverse continents without a single stop. In 2025, airlines are pushing boundaries, with Qantas' non-stop Perth to London and Singapore Airlines' Singapore to New York routes leading the charge for the world’s longest commercial flights.
