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.
