Southwest Airlines posts all its flight schedules directly on its website. The airline usually posts its schedules at least six months in advance, but all flight times are subject to change.
By entering a departure city, destination city, and date on Southwest.com, travelers can look up all flights scheduled on that route on any given date in the next six months. Southwest also gives the option to display flight schedules on a weekly basis.
In addition to flight schedules, Southwest.com hosts additional travel tools such as a route map and a flight status checker, the latter of which gives more up-to-date information for flights in progress.
