Southwest cancellations are usually weather, staffing, or mechanical issues—not a system-wide failure

Southwest Airlines cancels flights for the same reasons most carriers do: severe weather, crew shortages, aircraft maintenance problems, or air traffic control delays. A single cancelled flight does not mean the airline is collapsing or that all Southwest routes are grounded. What matters is whether your flight is affected and what Southwest will do about it.

The most visible cancellation event in Southwest's recent history was in December 2022, when a winter storm combined with staffing shortages caused roughly 2,000 cancellations over several days. That was unusual. On a normal day, Southwest cancels a small percentage of its schedule, as do other major carriers. You can check whether cancellations are happening today by looking at real-time flight status on Southwest's website or on flight tracking sites like FlightAware.

If you have a Southwest flight booked and want to know its current status, go to Southwest.com, enter your confirmation number, and check the flight details. If the flight shows as cancelled, Southwest will contact you by email and phone. You do not have to wait for the airline to reach out—you can rebook when ready.

  • If your flight is cancelled, Southwest will automatically rebook you on the next available flight at no extra cost, or you can request a refund.
  • During widespread cancellations (rare events affecting many flights), Southwest's phone lines become overloaded; using the website or mobile app is faster.
  • You are may have access to to a refund of your ticket price if you do not want to fly on the rebooked flight, regardless of the reason for cancellation.

How to check if your Southwest flight is cancelled

The fastest way is to visit Southwest.com and use the "Check Flight Status" tool. You will need your confirmation number (a six-character code from your booking email) and either your last name or the phone number you used to book. Enter these details and the system will show you whether your flight is on time, delayed, or cancelled.

You can also use the Southwest mobile app, which updates in real time and will send you notifications if your flight status changes. If you booked through a travel website like Expedia or Kayak, those sites also show Southwest flight status, but going directly to Southwest is more reliable because the airline updates its own system first.

Flight tracking websites like FlightAware and Flightradar24 show cancellations across all airlines and can give you a sense of whether cancellations are widespread in your region. If you see many flights cancelled at your departure airport on a particular day, weather is usually the cause.

What Southwest does when it cancels your flight

Southwest automatically rebooks you on the next available Southwest flight to your destination at no extra charge. The airline will send you an email and text message with your new flight details. You do not need to call or visit the airport—the rebooking happens in the system.

If no Southwest flight gets you to your destination on the same day, Southwest will rebook you on the next day's flight. If you need to reach your destination urgently and do not want to wait, you can request a refund of your ticket price instead. This refund is not a travel credit—it is actual money back to your original payment method, and you can use it however you wish.

If your cancelled flight was the first leg of a connecting trip, Southwest will rebook your entire itinerary. If the rebooking creates a long gap between flights, you may be may have access to to a meal voucher or hotel stay, depending on the length of the delay and the reason for cancellation. Contact Southwest directly to discuss what they will cover.

When weather causes cancellations

Severe weather—thunderstorms, snow, ice, high winds, or poor visibility—is the most common reason for flight cancellations. When weather grounds flights, the airline is not required by law to pay you compensation, because weather is considered an "act of God" beyond the airline's control. However, Southwest will still rebook you or refund your ticket.

Winter storms in the northern United States and summer thunderstorms in the South and Midwest cause the most cancellations. If you are flying during severe weather and your flight is cancelled, expect long phone lines and full flights on the next available departure. Rebooking may take longer than usual because many passengers are competing for the same seats.

You can reduce the risk of weather cancellations by checking the forecast for your departure and arrival cities before you fly. If severe weather is predicted, consider flying a day earlier or later if your schedule allows. Airlines sometimes issue travel waivers during weather events, which let you change your flight to a different date or route without paying a change fee.

Staffing and mechanical issues

Crew shortages—pilots, flight attendants, or ground staff unavailable—cause cancellations when Southwest cannot staff a flight. Mechanical problems, such as an engine issue or avionics malfunction discovered during preflight checks, also result in cancellations. Unlike weather, these are within the airline's control, but they are also less predictable and harder to prevent.

If your flight is cancelled due to crew shortage or mechanical issues, you have the same rebooking and refund options as with weather cancellations. However, you may also be may have access to to compensation under Department of Transportation rules if the cancellation was within the airline's control and you were not notified at least 14 days in advance. This compensation is separate from your ticket refund and can be $400 or more per passenger, depending on the flight length.

To claim compensation, you will need to contact Southwest directly or file a claim with the Department of Transportation. Keep your booking confirmation, cancelled flight details, and proof of the reason for cancellation (the airline's email or website statement).

What to do if you cannot reach Southwest by phone

During widespread cancellations, Southwest's phone lines become so overloaded that wait times can exceed two hours. The website and mobile app are much faster. You can rebook your flight, request a refund, or check your new flight details without speaking to anyone.

If you need to speak with an agent, try calling early in the morning or late at night when fewer people are calling. You can also reach Southwest through its social media accounts (Twitter and Facebook), where customer service representatives respond to direct messages, sometimes faster than the phone line.

If you booked through a travel website like Expedia, you can also contact that site's customer service, though they will ultimately direct you to Southwest for rebooking and refunds.

How to prepare for the possibility of cancellation

Book flights with enough time between connections that a single cancellation will not cause you to miss your next flight. If you have a tight connection and your first flight is cancelled, you will miss the second one, and rebooking becomes complicated. A two-hour gap between domestic flights is safer than a one-hour gap.

Check the weather forecast for your departure and arrival cities the day before you fly. If severe weather is predicted, consider whether you can fly earlier or later. Many airlines issue travel waivers during weather events, which let you change your flight without paying a fee.

Keep your confirmation number and booking email accessible on your phone. If your flight is cancelled, you will need the confirmation number to rebook or check status. Take a screenshot of your booking details so you have them even if your email is not working.

Can I change my flight to a different airline if Southwest cancels mine?

Southwest will not pay for you to fly on another airline. However, you can request a refund and then book a flight on another carrier using your own money.
