If the data is any indication, Americans do not like staying in the same place for an extended period of time. In 2019 alone, $1.1 billion was spent on travel in the U.S., a figure that ultimately generated $2.6 trillion in total economic output and helped support upwards of 15.8 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 2019, 811 million passengers flew on flights between two American destinations.

Of course, COVID-19 dramatically affected travel in 2020, hamstringing the industry and grounding thousands of domestic and international flights. To find out which domestic flights persisted during initial shutdowns, Stacker compiled a list of the most common domestic flights from San Diego International Airport using data from the U.S. Bureau of Transportation Statistics. Destinations are ranked by total passengers in the second quarter 2020.
