The Busiest Air Routes? Here Are the Top 10

With load factors in the mid-80’s year-round, it sometimes seems like every flight is a popular flight. But some flights are more popular than others.

Routesonline combined schedule and passenger data from OAG and Sabre to compile a list of the busiest air routes in North and South America.

Here are the top 10:

  1. Mexico City – Cancun
  2. Los Angeles – New York
  3. Mexico City – Monterrey
  4. New York – Chicago
  5. San Francisco – Los Angeles
  6. Guadalajara – Mexico City
  7. Los Angeles – Seattle
  8. San Francisco – New York
  9. New York – Atlanta
  10. Honolulu – Kahului

Surprisingly perhaps, three of the 10 busiest air routes in North America turned out to be in Mexico. The very busiest, with 3,682,028 passengers during the 12-month period through October 2017, was the 805-mile flight between Mexico City and Cancun. Average fare: $72.22.

Second on the list is a bit more predictable: the Los Angeles to New York route, with 2,873,316 passengers for the year, at an average fare of $337.66. That’s the most expensive of the top-10 flights, and also the longest flight, at around 2,474 miles.

The 10th-busiest route is also the shortest: Honolulu to Kahului, at just 105 miles, with an average fare of $65.76.
