Southwest Airlines reservations phone number and when to call

Southwest Airlines reservations can be made by phone at 1-800-I-FLY-SWA (1-800-435-9792). This number works for new bookings, changes to existing reservations, and questions about your flight. The line is open from early morning until late evening, seven days a week, though wait times vary by time of day and season.

Call this number if you want to book a flight, modify a reservation you already have, add checked bags, purchase seat assignments, or ask about fare rules before you commit. You can also reach this line to discuss Southwest's Rapid Rewards frequent flyer program or to add a companion pass to your booking.

If you have already booked online and only need to check your reservation details or print your boarding pass, the website or mobile app will be faster than calling. But if you want to talk through options, compare fares across dates, or need help understanding what you are buying, the phone line connects you to a real person who can walk you through it.

What to have ready before you call

Gather a few pieces of information before you dial. If you are booking a new flight, have your departure and arrival cities ready, your travel dates, and the number of passengers. If you are changing an existing reservation, have your confirmation number — a six-character code Southwest sent you by email when you booked.

Have a payment method available if you are booking or paying for add-ons like checked bags or seat assignments. Southwest accepts major credit cards, debit cards, and gift cards. If you are a Rapid Rewards member, have your account number handy so the agent can explore points or check your balance.

Write down any specific requests before you call — for example, if you want to sit near the front of the plane or need to travel with a companion on the same flight. This helps the agent understand what you need and speeds up the conversation.

Wait times and best times to call

Southwest's phone lines handle thousands of calls daily, so wait times depend heavily on when you call. Early morning — between 6 a.m. and 9 a.m. on weekdays — typically has shorter waits because fewer people are calling. Mid-morning and early afternoon on weekdays are also usually faster than evenings or weekends.

Avoid calling on Friday afternoons, Saturday mornings, and Sunday afternoons, when leisure travelers are booking weekend trips. Holiday periods and the days when ready before major travel holidays see the longest waits. If you can book on a Tuesday or Wednesday morning, you will likely spend less time on hold.

Southwest does not offer a callback feature on the reservations line, so you will wait on the phone. Some callers use the time to handle email or other tasks, but be ready to answer questions when an agent picks up.

What you can and cannot do by phone

The reservations line handles most common needs: booking flights, changing dates or times, canceling reservations, adding checked bags, purchasing seat assignments, and discussing fares. You can also ask about Southwest's policies — for example, how many bags fly free, what the cancellation policy is, or whether you can bring a pet on board.

Some requests require a different department. If you have a question about a flight that already departed, a lost bag, or a refund for a flight you canceled weeks ago, the agent may transfer you to customer relations or baggage services. If you are calling about a group booking of 10 or more passengers, you will be directed to Southwest's group sales team.

You cannot purchase travel insurance or book hotels and rental cars through the reservations line, though Southwest's website offers those options. You also cannot make changes to a reservation through a third-party booking site by calling Southwest directly — you would need to contact the site where you booked.

Alternative ways to reach Southwest

If you prefer not to call, Southwest offers several other ways to reach the airline. The website at southwest.com lets you book, change, and cancel reservations without speaking to anyone. The mobile app has the same features and also shows your boarding pass and real-time flight status.

Southwest's social media accounts on Twitter and Facebook respond to direct messages and public posts, though this is usually slower than calling. You can also start a chat session on the website during business hours, though wait times for chat can be longer than for phone calls during busy periods.

If you are at the airport, ticket counters and gate agents can help with many reservation questions, though they prioritize passengers who are actively checking in or boarding. Calling ahead is usually faster if you have time before your flight.

Understanding Southwest's reservation policies

Southwest does not charge change fees, which means you can move your flight to a different date or time without paying extra — though you may owe the difference if the new flight costs more. This is one reason many people call to modify reservations instead of canceling and rebooking.

If you cancel a reservation, Southwest holds the fare as a credit toward a future flight for one year from your original booking date. You cannot transfer this credit to another person, and it expires if you do not use it. The agent can explain exactly when your credit expires and what flights are available for the price you paid.

Southwest's "Bags Fly Free" policy means your first two checked bags do not cost extra, but the agent can tell you about fees for additional bags, oversized luggage, or special items like golf clubs or musical instruments. Seat assignments are free when you check in online 24 hours before departure, but you can pay to choose a specific seat in advance by calling.

Frequently Asked Questions

How long will I wait on hold when I call Southwest?

Wait times range from a few minutes to over an hour depending on the time of day and season. Weekday mornings typically have shorter waits than evenings or weekends. During peak travel periods like holidays, expect longer waits regardless of when you call.

Can I book a flight for someone else by calling Southwest?

Yes, you can book a flight for another person by providing their name, date of birth, and contact information. The agent will need a payment method in your name. The passenger will receive a confirmation email with their reservation details and can check in using their name and confirmation number.

What if I need to cancel my flight and get a refund instead of a credit?

Southwest does not issue refunds for canceled reservations — you receive a credit toward a future flight instead. The only exception is if Southwest cancels the flight or makes a significant schedule change. The agent can explain your options and help you rebook on a different flight if you prefer.

Do I have to call to add a companion pass to my reservation?

No, you can add a companion pass through the website or app if you have one. But calling can be helpful if you want to discuss which flights work best for both passengers or if you have questions about how the companion pass works.

Can Southwest's phone line help if I booked through a travel website?

Southwest can look up your reservation by name and confirmation number, but changes to bookings made through third-party sites must go through that site. Southwest's agent can explain what options are available, but you may need to contact the travel website directly to make changes.
