Southwest Airlines maintains a free flight schedule on its website. The schedule is searchable by airport of origin and destination. The schedule is updated periodically, which is noted on the web page.
In addition to the flight schedule, Southwest provides an interactive flight map. Users can view all non-stop and connecting flights that pass through a selected city. The map also allows users to begin the purchasing process from the page, visually selecting the origin and destination. Travelers looking for one-way tickets can quickly swap origin and destination with a single click. The map covers the United States, Mexico and the Caribbean.
