Main airports of Southwest Airlines - daily departures 2018

Despite being headquartered in Dallas, Southwest Airlines’ busiest airport is not located in Texas; that honor goes to Chicago Midway International Airport, from which 225 Southwest flights departed daily in November 2018.

Low-cost carriers

Low-cost carriers differentiate themselves from full-service carriers by offering lower ticket prices generally through two methods. First is to charge additional fees for items usually included by full-service carriers, such as food and beverages, and checked luggage. Second is by often operating out of secondary airports, such as Midway airport, mentioned above, which generally charge lower usage costs to airlines. Southwest Airlines is the worlds’ largest low carrier, both in terms of passengers carried and revenue.

U.S. airlines

In 2018, Southwest Airlines had the equal-highest domestic market share of all U.S. airlines – although little separates the top four. However, the three full-service carriers which round out the top four - American Airlines, Delta and Unite - are all more profitable. This is likely due to Southwest’s low-cost business model and lack of international destinations. Despite these limitations, Southwest consistently receives higher customer satisfaction scores than the leading full-service providers.
