Southwest Airlines Co. (LUV) Price and Market Data

Southwest Airlines Co. is the largest domestic airline in the United States by passengers boarded. The carrier operates nearly 800 aircraft, all within an all-Boeing 737 fleet. While Southwest serves some longer routes and offers select features for business travelers, its core focus remains short-haul leisure travel, supported by a simple cabin layout and a point-to-point network. In early 2026, Southwest updated its cabins to include rows with extra legroom, revised its ticketing and merchandising to introduce assigned seating, and expanded its fare lineup with additional categories, including a basic economy option appearing for the first time in travel aggregators’ search results and competing more directly with other airlines.
