How to Book a Southwest Flight Online
The online reservation process generally involves choosing your trip type, entering your travel details, comparing available flights, selecting a fare, providing passenger information, and completing payment.
1. Choose Your Trip Type
Start by deciding whether you need:
One-way flight
Round-trip flight
A multi-city itinerary, when available
Southwest's online booking system allows customers to book one-way or round-trip travel for up to nine passengers by entering the origin, destination, and travel dates.
2. Enter Your Departure and Destination
Enter the airport or city where your journey begins and your destination.
For example:
Dallas to Las Vegas
Chicago to Orlando
Denver to Phoenix
Los Angeles to San Diego
Houston to Atlanta
Southwest serves a broad network of destinations, and its online flight search displays currently available fares for selected routes and dates.
Tip: If your schedule is flexible, check nearby airports and alternative travel dates. A small change in your departure date can sometimes produce a different fare.
3. Select Your Travel Dates
Choose your departure date and, if applicable, your return date.
Flexible travelers can use Southwest's Low Fare Calendar to compare the lowest available fares across different days of a month. Southwest also recommends shopping early and checking fares regularly because prices can change.
When comparing dates, consider:
Weekend versus weekday travel
Holiday periods
School vacation periods
Morning versus evening departures
Alternative nearby airports
4. Compare Available Southwest Flights
After entering your trip information, review the available flights.
Compare more than just the displayed ticket price. Look at:
Departure and arrival times
Total journey duration
Nonstop versus connecting options
Fare type
Seat-selection benefits
Boarding benefits
Change and cancellation flexibility
Baggage benefits
A cheaper fare may not always provide the features that matter most for your trip.
5. Select the Right Fare
Southwest currently provides four primary fare bundles: Basic, Choice, Choice Preferred, and Choice Extra. Each offers a different combination of price, flexibility, seating, boarding, and other benefits.
Basic
Basic is designed for travelers primarily looking for a lower-priced option. It includes a standard seat assigned at check-in, while additional seating options may be available for purchase.
Basic is also more restrictive: it cannot normally be changed unless you first upgrade to another eligible fare.
Choice
Choice is positioned as a value-oriented option and allows travelers to choose a standard seat at booking, subject to availability. It also provides more flexibility than Basic.
Choice Preferred
Choice Preferred adds enhanced seating and boarding benefits. Travelers can choose a Preferred or Standard seat at booking, subject to availability, and receive an earlier boarding group.
Choice Extra
Choice Extra is the most comprehensive of the four fare bundles. It includes the ability to choose an Extra Legroom, Preferred, or Standard seat at booking, Group 1 boarding, and two free checked bags under the applicable terms.
6. Review the Seat Map
Southwest now uses assigned seating on its flights. The seat options available to you depend on the fare purchased and other eligibility factors.
During booking, a seat map can appear after selecting your flight and entering passenger information. Depending on your fare, you may be able to select:
Extra Legroom seats
Preferred seats
Standard seats
If your fare does not include your preferred seat, an additional seat-selection charge may apply when available.
If you do not select a seat when eligible, you may be able to return later through Southwest's website or app.
7. Enter Passenger Information Carefully
Enter passenger details exactly as they should appear on the travel documents.
Double-check:
First and middle names
Last name
Date of birth, when requested
Contact information
Rapid Rewards number, if applicable
Known Traveler Number, if applicable
Errors in passenger information can create complications later, so review the details before continuing.
8. Review Baggage and Optional Services
Before paying, review baggage requirements and any optional services associated with your fare.
Southwest provides online baggage tools for customers to check bags and manage baggage-related information.
Your fare can affect baggage benefits. For example, Choice Extra currently includes two free checked bags under the applicable terms, while Basic, Choice, and Choice Preferred may have checked-bag fees depending on eligibility and circumstances.
9. Apply Eligible Travel Credits or Rewards
If you have an eligible Southwest flight credit or Rapid Rewards benefits, review whether they can be applied to your reservation.
Southwest states that the name on a flight credit must match the name on the reservation. Eligible transferable flight credits can also have specific transfer rules.
10. Complete Payment and Confirm Your Reservation
Before submitting payment, review the entire itinerary.
Check:
Passenger names
Route
Travel dates
Departure and arrival times
Fare type
Seat selection
Baggage information
Total price
Payment details
After completing the booking, save your confirmation information. You can use the confirmation details later to retrieve and manage your reservation. Southwest provides an online reservation-retrieval tool using the confirmation number and passenger name.

How to Find Cheaper Southwest Flights
Finding a low fare requires more than simply searching once.
Use the Low Fare Calendar
If your dates are flexible, compare fares across multiple days. Southwest specifically recommends its Low Fare Calendar for identifying the lowest available price for each day of a month.
Compare Fare Value, Not Just Price
A Basic fare may initially look attractive, but a higher fare could provide benefits that are valuable for your trip.
For example, someone who needs flexibility may prefer Choice, Choice Preferred, or Choice Extra rather than selecting Basic solely because it has the lowest displayed price.
Check Different Travel Dates
Try moving your trip by one or two days. Also compare:
Early-morning departures
Midday flights
Late-night flights
Weekday departures
Weekend departures
Book When You Find a Suitable Fare
Southwest notes that fares can change at any time while customers are shopping. Its guidance recommends shopping early and checking fares regularly.
Southwest Flight Booking for Families
Families should pay particular attention to seating, passenger information, baggage, and travel requirements before completing a reservation.
Since Southwest now has assigned seating, families should review the available seat map during the booking process and select appropriate seats when their fare permits it.
If you are traveling with children, review Southwest's current children and family travel requirements before finalizing your trip.
Southwest Flight Reservations: How to Manage Your Trip
After booking, you may need to make changes, review your itinerary, check baggage, or manage other travel details.
Southwest allows many flight changes online through its website or app. According to its current guidance, most flights can be changed online, while Basic fares have additional restrictions. Eligible changes may require payment of a fare difference.
You can also add certain information to an existing reservation, including a Rapid Rewards account number or Known Traveler Number.

What to Check Before Your Southwest Flight
After making your reservation, use this checklist:
Confirm your flight number.
Verify departure and arrival airports.
Check the travel date and local departure time.
Review your selected fare.
Confirm your seat assignment.
Check baggage requirements.
Save your confirmation number.
Complete online check-in when available.
Review any schedule changes before leaving for the airport.
Southwest's Help Center provides separate resources for planning and booking, getting ready, day-of-travel information, baggage, changes, cancellations, and assigned seating.
Is Southwest Flight Booking Online Worth It?
Yes, online booking can be convenient because you can compare available flights, review fare options, select eligible seats, and manage many reservation details without visiting a ticket counter.
The most important step is to compare the total value of each fare, rather than automatically choosing the lowest number displayed. A slightly higher fare may provide seating, boarding, baggage, or flexibility benefits that better match your travel needs.
For the latest fare rules and booking conditions, always verify the details displayed during your reservation and review the airline's current policies.
