Missing a Southwest Airlines flight indicates that you were unable to board the aircraft on time. Any airline, including Southwest, can cause you to miss a flight for a variety of reasons, including being late to the airport, experiencing unforeseen delays, or dealing with personal issues that prohibit you from being at the departure gate in time. Your travel plans may be disrupted if you miss a flight, and you will need to work with the airline to make other arrangements to get where you're going. It's crucial to get in touch with Southwest Airlines directly to explain your issue and look into your alternatives for rebooking or finding a solution that works for you.
