Southwest Airlines Co. is a major United States airline headquartered in Dallas, Texas, and is the world’s largest low-cost carrier.
The airline was established in 1967 by Herb Kelleher as Air Southwest Co. and adopted its current name, Southwest Airlines Co., in 1971, when it began operating as an intrastate airline wholly within the state of Texas, first flying between Dallas and San Antonio. The airline has more than 58,000 employees as of September 2018 and operates more than 4,000 departures a day during peak travel season.
As of December 2018, Southwest carries the most domestic passengers of any United States airline. The airline has scheduled services to 99 destinations in the United States and ten additional countries. Service to four destinations in Hawaii is coming in late 2018 or early 2019 subject to FAA approval, with routes to be decided on and announced in the near future.
