Long-haul flying is one of the wonders of commercial air travel, transporting passengers across the globe on nonstop services lasting several hours. While precise definitions of what constitutes “long-haul” vary among airlines and authorities, the International Air Transport Association (IATA) defines long-haul as flights lasting between six to 16 hours, while other definitions look at flight distance, typically categorizing routes over 3,000 miles as long-haul.
