Southwest Airlines customer service phone number

Southwest Airlines' main customer service line is 1-800-I-FLY-SWA (1-800-435-9792). This number works for reservations, changes to existing bookings, and general questions about your flight. The line is open from early morning through late evening, seven days a week, though wait times vary by time of day and season.

When you call, have your confirmation number ready — it's the six-character code Southwest sent you by email or text after you booked. If you're calling about a flight that already happened, have your name and the date of travel. Southwest does not charge extra to speak with an agent by phone, and there is no separate booking line; the main number handles all reservation requests.

If you're calling from outside the United States, the international number is 1-210-792-7662. This line may have longer wait times and different hours depending on your location, so calling the domestic number from a VoIP service or calling app sometimes works faster if you're abroad.

What to expect when you call

After you dial, an automated system will ask what you need — booking a flight, managing an existing reservation, or something else. Select the option that matches your reason for calling. The system may also ask for your confirmation number at this stage, which speeds up the process because it routes you to the right department faster.

Wait times range from a few minutes to over an hour depending on the time you call. Early morning (before 8 a.m. Eastern) and late evening (after 8 p.m. Eastern) typically have shorter queues. Avoid calling on Mondays, Fridays, and the day after major holidays, when call volume peaks. If you reach a long wait, you can hang up and call back later — Southwest does not penalize you for disconnecting.

Once an agent picks up, they can book a new flight, change your seat, modify your travel dates, add a companion pass, or answer questions about baggage, boarding, or refunds. The agent cannot process refunds to your original payment method over the phone for most bookings — those go through the website — but they can issue travel credits or vouchers when ready.

When to call versus using the website

The Southwest website and mobile app handle most tasks faster than calling: booking a flight takes minutes online versus 20 to 40 minutes on the phone, and changing your seat or checking in is when ready on the app. Call only when the website shows an error, when you need to make changes that the app won't allow, or when you want to discuss options with a person before committing.

Common reasons to call instead of using the website include adding a companion pass to an existing booking, requesting a refund instead of a travel credit, disputing a charge, or asking about special accommodations for a disability or medical condition. Agents also handle situations where your name doesn't match your ID exactly, which sometimes blocks online check-in.

If you're trying to book a flight that the website says is sold out, calling does not give you access to hidden inventory — the agent sees the same availability you do. However, an agent can sometimes suggest alternative flights or dates that might work for your schedule.

Booking a new flight by phone

To book a new flight by phone, have your travel dates, departure and arrival cities, and number of passengers ready. Tell the agent whether you want a one-way or round-trip flight and your preferred time of day. The agent will show you available flights and fares, explain the differences between Southwest's fare types (Wanna Get Away, Anytime, and Business Select), and let you choose.

Southwest charges the same price by phone as online, so there is no advantage to calling for the fare itself. However, if you're unsure about which fare type suits you, an agent can explain what each includes — for example, Business Select includes priority boarding and a free drink, while Wanna Get Away is the lowest price but boards last. After you choose, the agent takes your payment information and sends your confirmation number by email and text.

The entire call usually takes 30 to 45 minutes if you're booking a round-trip flight for multiple passengers, because the agent must confirm each leg and each person's details. If you're in a hurry, booking online takes half that time.

Making changes to an existing booking

To change a flight you already booked, call with your confirmation number and the name on the reservation. You can change your travel date, time, or destination, add or remove passengers, or switch to a different fare type. If your new flight costs less, Southwest issues a travel credit for the difference. If it costs more, you pay the difference by credit card or debit card over the phone.

Some changes are free — moving to a different flight on the same day, for example — while others charge a fare difference. Southwest does not charge a change fee itself, but you pay if the new flight is more expensive. Cancellations are also free; you receive a travel credit good for one year from your original booking date, which you can use for any Southwest flight or transfer to another person.

If you're within 24 hours of your flight, the agent can make the change when ready and issue a new boarding pass. If you're further out, the change takes effect right away, but you'll check in online or at the airport as usual.

Handling refunds and travel credits

Southwest does not offer cash refunds for most bookings — instead, you receive a travel credit that works like a gift card for any future Southwest flight. The credit is good for one year from your original booking date. You can use it yourself or give the confirmation number to someone else to book a flight.

If you paid with a credit card and want to dispute the charge instead of accepting a travel credit, you can ask the agent about a refund, but most bookings do not may have access to. Refunds are available only for flights you paid for but did not use and did not convert to a credit, or in rare cases like a flight cancellation where Southwest cannot rebook you. The agent can explain whether your situation qualifies.

To use a travel credit, you do not need to call — you can book online or on the app using the confirmation number from your original reservation. The system will recognize the credit and explore it to your new booking automatically.

Special situations and accommodations

Call Southwest if you need to request a wheelchair, oxygen, or other disability-related accommodations; if you're traveling with an emotional support animal or service dog; or if you have a medical condition that affects your travel. The agent can note these in your reservation so the airport staff and flight crew are prepared. You should call at least 24 hours before your flight, though calling earlier gives Southwest more time to arrange what you need.

If you're traveling with an infant and want to purchase a seat for a car seat instead of holding the baby, call to add that seat to your reservation. You can also call if you're unsure whether your pet meets Southwest's size and breed requirements, or if you want to confirm that your musical instrument or sports equipment will fit in the overhead bin.

For questions about military discounts, senior fares, or group bookings of 10 or more passengers, the main number can transfer you to the right department or provide a direct line.

Frequently Asked Questions

Is there a fee to book or change a flight by phone?

No. Southwest does not charge a phone booking fee or a change fee. You pay only the fare for the flight itself, or the difference if you're changing to a more expensive flight. This is the same price you would pay online.

Can I check in by phone?

No. Southwest does not offer phone check-in. You must check in online at southwest.com or on the mobile app starting 24 hours before your flight, or at an airport kiosk or counter on the day of travel. Checking in online is faster and lets you choose your boarding position.

What if I'm on hold for a very long time?

You can hang up and call back later without penalty. Southwest does not charge for disconnecting or require you to stay on the line. If the wait is over 30 minutes, try calling back in a few hours or the next day when volume is lower.

Can I book a flight for someone else?

Yes. When you call, provide the passenger's name, date of birth, and contact information. The agent will book the flight under that person's name, and Southwest will send the confirmation to the email address you provide. The passenger can then check in and manage the booking using the confirmation number.

What if my name doesn't match my ID exactly?

Call Southwest before your flight to report the mismatch — for example, if your booking says "Robert" but your ID says "Bob", or if your last name has a hyphen on your ID but not in the system. The agent can update your reservation so you don't get stopped at the airport during check-in.
