Southwest Airlines Route Map

Southwest Airlines is the largest domestic airline in the United States by passengers. It was founded in Texas in 1967, first flew in 1971, is based at Dallas Love Field, and flies an all Boeing 737 fleet.

Instead of a few hubs, Southwest flies point to point between large bases, so many of its routes skip the big connecting airports. Denver has the most routes on this page, followed by Chicago Midway, Nashville, Dallas Love Field and Baltimore. Beyond the mainland it flies to Hawaii, Mexico, Central America and the Caribbean.

Below is the network on two maps, domestic and international, every route with its distance, and the longest and shortest flights Southwest operates.
