+100 Daily Flights: The World’s 5 Busiest Airline Routes

There were 10 routes in 2024 that had an average daily frequency of 100 flights or more (or more than four flights per hour). Of these, seven were in greater Asia, one in Australia, and two in South America. None were in North America, Europe, or Africa, and all the busiest flights were domestic flights. Most of the busiest routes are between the country’s largest cities (e.g., Hanoi to Ho Chi Minh City), but some are to leisure destinations (like Jeju in South Korea). In the United States, the four busiest routes are Atlanta-Orlando, Honolulu-Kahului, Las Vegas-Los Angeles, and Denver-Phoenix. However, none of these make the list below.
