While American Airlines has grown tremendously in Austin – quadrupling destinations and doubling flights – Southwest remains the largest carrier in the market by a wide margin. In fact it carries an even larger share of Austin traffic than it did three years ago, before the pandemic.
United and Delta have shrunk a bit. So has JetBlue. Allegiant has gown, while Spirit and Frontier have shrunk. Few would have guessed that of Delta, which still calls Austin a focus city.
