Southwest will rebook you on the next available flight at no extra charge

If you miss a Southwest flight, you are not charged a rebooking fee. Southwest automatically places you on the next available flight to your destination, whether that flight leaves the same day or later. You do not need to purchase a new ticket—your original booking remains valid, and the airline straightforward moves you to a different flight number.

The key difference between Southwest and most other airlines is that you keep the full value of your ticket. You are not downgraded, charged a change fee, or forced to buy a new seat. This applies whether you miss your flight because of traffic, a long security line, or any other reason on your end.

However, the specific flight you are rebooked onto depends on availability and how far in advance you contact Southwest. If you realize you will miss your flight, call the airline when ready rather than waiting until after your flight departs. The sooner you notify them, the more options they may have to get you on a flight that day.

Key Takeaways

  • Southwest does not charge a rebooking fee when you miss a flight; you are automatically placed on the next available flight to your destination.
  • Calling Southwest before your flight departs gives you more control over which later flight you are rebooked onto.
  • If you miss your flight and do not contact the airline, your ticket may be cancelled entirely, and you will lose the fare.
  • Standby flights are not may provide, so arriving at the airport early for your new flight is important to confirm your seat.
  • If you miss a connection because your first flight was delayed, Southwest treats this differently and will rebook you without penalty.

Call Southwest before your flight leaves if you know you will be late

The moment you realize you cannot make your flight, call Southwest's customer service line. This is the single most important step. When you call before departure, a representative can place you on a specific later flight and confirm your seat assignment. You avoid the risk of your ticket being cancelled, and you know exactly when you will depart.

Southwest's phone number for rebooking is on your confirmation email and on their website. Wait times can be long during peak travel hours, so be prepared to hold. Have your confirmation number ready when you call.

If you do not call before your flight departs, Southwest will automatically cancel your ticket. Once cancelled, you lose the fare entirely—you cannot use it on a future flight. This is the most common and costly mistake passengers make. Even if you are only 10 minutes late, calling ahead prevents this outcome.

What happens if you do not contact Southwest before departure

If your flight departs without you and you have not called the airline, your ticket is forfeited. Southwest does not hold your seat or keep your reservation active. The fare is gone, and you will need to purchase a new ticket if you still want to travel.

This policy exists because Southwest needs to know whether to hold your seat or release it to another passenger. Once the aircraft door closes, the airline assumes you are not coming and moves forward with the flight. There is no grace period and no way to recover the fare after the fact.

The only exception is if your first flight was delayed and you missed a connection as a result. In that case, Southwest will rebook you on the next flight to your final destination at no charge, even if you did not contact them.

Rebooking on a standby basis and seat assignments

When Southwest rebooks you, you are typically placed on a standby list for the next available flight rather than may provide a seat on a specific flight. This means you have a reservation, but your seat is not confirmed until you check in at the gate. Standby passengers board after all passengers with confirmed seats.

To increase your chances of getting on your rebooked flight, arrive at the airport early—at least two hours before departure for a domestic flight. Check in at the ticket counter or kiosk as soon as you arrive. The earlier you check in, the higher you move on the standby list.

If the flight is full and you do not get a seat, you will be moved to the next flight with availability. This process repeats until you are confirmed on a flight. During busy travel periods, standby rebooking can take several hours or even push your travel to the next day.

How to prevent missing your Southwest flight

Arrive at the airport at least two hours before a domestic flight and three hours before an international flight. This gives you a buffer for traffic, parking, and security lines. Many passengers who miss flights underestimate how long these steps take, especially during peak travel times.

Set a phone alarm for 90 minutes before your departure time as a reminder to leave for the airport. Check your confirmation email the night before to confirm your flight time and gate information (though gates can change on the day of travel).

If you are running late, text or call the airport's ground transportation hotline or your ride to let them know. Do not wait until you are at the airport to realize you will not make it. The earlier you know, the earlier you can call Southwest and find a rebooking.

Missed connections versus missed flights

A missed connection is different from a missed flight. If Southwest's first flight is delayed and you miss your connecting flight as a result, Southwest will rebook you on the next available flight to your final destination at no charge. You do not need to call ahead; the airline handles this automatically because the delay was their responsibility.

A missed flight is when you do not arrive at the gate in time for departure, regardless of the reason. This is your responsibility, and the rebooking process described above applies. Southwest will not charge you a fee, but you must contact them to find a new flight.

If you are unsure whether your situation qualifies as a missed connection, call Southwest and explain what happened. They will determine whether the delay was within their control and handle your rebooking accordingly.

What to do at the airport after missing your flight

Go directly to the Southwest ticket counter. Do not wait in the security line or at the gate. The ticket counter staff can rebook you when ready and answer questions about available flights. Bring your ID and have your confirmation number ready.

If the ticket counter has a long line, ask a Southwest employee whether you can call customer service instead. Sometimes calling is faster, and the representative can rebook you while you wait in line. Once you have a new flight assignment, you can proceed through security and to your gate.

If you are traveling with luggage that was already checked, ask the ticket counter whether it will be transferred to your new flight or held for you to collect. Southwest typically transfers bags to your new flight automatically, but confirm this before you leave the counter.

Frequently Asked Questions

Do I lose my ticket if I miss a Southwest flight?

Only if you do not contact Southwest before your flight departs. If you call ahead, your ticket remains valid and you are rebooked on the next available flight. If you do not call and your flight leaves without you, the ticket is cancelled and the fare is forfeited.

Can I get a refund if I miss my Southwest flight?

No. Southwest does not refund fares for missed flights. However, the value of your ticket is transferred to your new flight, so you are not paying twice. If you need to cancel your trip entirely, you can use the fare credit toward a future flight within one year.

Will I have to pay extra to be rebooked on a later flight?

No. Southwest does not charge rebooking fees. You keep the full value of your original ticket and are placed on the next available flight at no additional cost.

What if all flights are full and I cannot get rebooked the same day?

You will be placed on a standby list for the next available flight with open seats. This may be the next day during busy travel periods. You are not charged extra, and your ticket remains valid. Arrive early at the airport to check in and move up the standby list.

How long do I have to call Southwest after missing my flight?

Call as soon as you realize you will miss your flight—before it departs. If you call after your flight has left, your ticket may already be cancelled. However, you can still contact Southwest to discuss rebooking options and whether your fare can be recovered.
