Busiest flight routes in America

If the data is any indication, Americans do not like staying in the same place for an extended period of time. In 2017 alone, U.S. travelers spent more than $1 billion getting to and from their destinations, a figure which ultimately generated $2.4 trillion in total economic output and helped support upwards of 15.6 million American jobs in the process.

While a significant percentage of these enormous figures stems from ground transportation such as buses, trains and cars, much of it comes from air travel, of which the majority is domestic. In 2017, 741.6 million passengers flew on flights between two American destinations, more than three times that of the year’s 223.4 million total international flyers.

Stacker looked at data from the T-100 Domestic Market (U.S. Carriers) table in order to list the 50 busiest domestic flight routes in the United States. The table, which was provided by the Bureau of Transportation Statistics, is from April 2018 and lists the total number of passengers that traveled between each pair of cities in either direction over the course of the month.

Read on to see which two cities have Americans going back and forth the most.
