With direct routes across continents and oceans, today's longest direct flight in the world redefines air travel. Among the most popular flights are those operated by Singapore Airlines from SIN to JFK, Qantas from Perth to London, and Emirates from Dubai to Auckland. The Airbus A350-900ULR and Boeing 787 Dreamliner are examples of specially developed aircraft that are needed for these ultra-long-haul trips, which last longer than 17 hours.
