Check your Southwest flight status on their website or app

Go to southwest.com and select "Check In" at the top of the page. Enter your confirmation number (the six-character code from your booking email) and your last name. The site will show your flight number, scheduled departure time, and current status — on time, delayed, or cancelled.

The Southwest mobile app works the same way. Open it, tap "Check In," enter your confirmation number and last name, and you'll see the same real-time status. The app updates every few minutes, so refresh it closer to your departure time for the most current information.

You can also call Southwest directly at 1-800-I-FLY-SWA (1-800-435-9792). Have your confirmation number ready. A representative will tell you your flight status and any known delays or changes.

Key Takeaways

  • If your flight is cancelled, Southwest will rebook you on the next available flight at no extra charge.

What the status page actually tells you

Southwest's status display shows whether your flight is "On Time," "Delayed," or "Cancelled." If it says "Delayed," the page usually includes an estimated new departure time, though this can change. The status does not always explain why — weather, mechanical issues, crew scheduling, or air traffic control delays all produce the same "Delayed" label.

The confirmation page also shows your gate number once you're within a few hours of departure. Gate assignments can change, so don't rely on an early gate number. Check again at the airport or on the app as you get closer to your flight time.

When to check and how often

Check your flight status the night before your flight and again two hours before departure. Most delays are announced within that window. If your flight shows "On Time" two hours out, it will almost certainly depart on schedule — Southwest rarely has last-minute delays without earlier warning.

If you're already at the airport, the departure boards in the terminal are more current than the website. Gate agents also have access to real-time information that the public site may not show yet, so ask at your gate if you see a delay posted but want confirmation.

What happens if your flight is delayed

Southwest does not automatically rebook you or offer compensation for delays. You stay on your original flight unless you choose to rebook. If the delay is long enough that you'll miss a connection, gate agents can rebook you on the next available Southwest flight to your final destination at no charge.

If you decide to cancel because of a delay, Southwest will issue you a travel credit for the full ticket price, valid for one year from your original booking date. You can use it for any future Southwest flight. This is different from a refund — Southwest does not refund ticket prices, only issue credits.

Delays versus cancellations

A delay means your flight will depart late but will still fly. A cancellation means the flight will not operate that day. If your flight is cancelled, Southwest will automatically rebook you on the next available flight to your destination, usually the same day or the next morning. You don't have to do anything — the airline handles the rebooking.

If you're rebooked on a flight that departs much later or at an inconvenient time, you can ask a gate agent or call Southwest to explore other options. You may be able to switch to a different airline if Southwest has no acceptable flights, though this is rare and depends on the reason for the cancellation.

Why the status page sometimes lags

The Southwest website updates every few minutes, but ground crews and pilots report delays to the airline's system, and that information takes time to reach the public site. If you're at the airport and see a delay on the departure board but the website still shows "On Time," the website will catch up within 10 to 15 minutes.

During busy travel periods — holidays, summer weekends, or days with widespread weather — the website can lag by 20 to 30 minutes. If you're close to your departure time and the website doesn't match what you see at the airport, trust the airport departure board.

Notifications and alerts

Southwest does not send automatic text or email alerts for delays under 15 minutes. If your flight is delayed by more than that, you may receive a notification, but it's not may provide. The safest approach is to check the status yourself rather than wait for a notification.

If you want to stay informed without checking repeatedly, set a phone reminder to check the status two hours before departure. This catches most delays and gives you time to adjust your plans if needed.

Frequently Asked Questions

How far in advance does Southwest post delays?

Most delays are posted 30 minutes to two hours before the scheduled departure time. Weather delays are sometimes known earlier. Mechanical or crew-related delays may not be posted until closer to departure. Check the status page two hours before your flight for the most reliable information.

Can I get a refund if my flight is delayed?

Southwest does not refund tickets for delays. You can use your ticket on a later Southwest flight or request a travel credit valid for one year. If the delay causes you to miss a connection, Southwest will rebook you on the next available flight at no charge.

What if the website says on time but the airport board says delayed?

Trust the airport departure board — it updates faster than the public website. The airport board reflects what the airline's internal system knows right now. The website will catch up within 10 to 15 minutes. If you're at the gate, ask the agent for the most current information.

Do I need to check in again if my flight is delayed?

No. If you've already checked in online or at a kiosk, your boarding position is locked in. A delay does not change your boarding group. You can check in up to 24 hours before your original scheduled departure time.

What should I do if my flight is cancelled?

Southwest will automatically rebook you on the next available flight to your destination. You don't have to do anything. If the new flight time doesn't work for you, call Southwest or visit a ticket counter to explore other options, including flights on different days or to nearby airports.
