Understanding Southwest Airlines Flight Change Policies

Southwest Airlines operates under a flight change policy that differs significantly from many other major carriers. Unlike airlines that charge change fees, Southwest allows passengers to change their flights without paying additional fees, though certain conditions and timing considerations apply. This guide provides information about how Southwest's change process works and what travelers should know before making changes to their reservations.

The foundation of Southwest's approach centers on the concept that if your plans change, you have options for modifying your trip. When you book a flight with Southwest, you receive what the airline calls a "Rapid Rewards® reservation," which represents your booking record in their system. This reservation can be modified in various ways depending on your situation and how much advance notice you provide.

Southwest's change policy applies to different fare types, though some restrictions may apply depending on which ticket type you purchased. Business Select fares, Anytime fares, and Wanna Get Away fares each have their own parameters for how changes can be made. Understanding which fare type you have will help you determine what options are available to you.

The airline processes changes through multiple channels, including their website, mobile application, and phone lines. Each channel offers similar functionality, though the mobile app and website tend to process changes faster than phone reservations. Changes made online typically show in your account within minutes, while phone-based changes may take longer to appear in the system.

Practical Takeaway: Before attempting any flight change, gather your confirmation number (found in your booking email or account) and your reservation details. Knowing your current flight information and desired change will streamline the process regardless of which method you use.

How to Change Your Flight Online and Through Mobile Devices

The Southwest website provides the most straightforward path for most passengers to modify their flights. The process begins by visiting southwest.com and locating the "Manage Reservations" section, which typically appears on the homepage. You'll need your confirmation number and the passenger's last name to access your booking. Once you log in, your current reservation displays with all flight details, including the date, time, airports, and fare information.

The online interface presents a "Change Flight" option for each passenger on the reservation. Clicking this option opens a new screen showing available flights for your chosen date and destination. You can select any available flight on any date moving forward, and Southwest's system automatically checks whether the new flight is available and calculates any fare differences.

If you're changing to a flight with a lower fare, Southwest issues you a travel credit for the difference. This credit appears in your Rapid Rewards account and remains valid for one year from the original booking date. You can apply this credit toward future bookings or allow it to sit in your account for when your plans change again. The travel credit transfers to whoever holds the original confirmation number, even if that person isn't the passenger flying.

The Southwest mobile app offers the same functionality as the website and often works faster on slower internet connections. The app's "Manage Reservations" section functions identically to the website version. Many travelers find the app convenient because you can make changes while away from home or waiting at the airport. Push notifications in the app can also alert you to changes in flight status, gate assignments, and other important information.

Mobile check-in through the app occurs 24 hours before departure and allows you to receive a digital boarding pass. If you change your flight before this 24-hour window, you'll need to check in again for your new flight. The app remembers your preferences and seat selections, making rebooking smoother if you switch to a different aircraft type where your original seat isn't available.

Practical Takeaway: Use the online or mobile option for changes made more than a few hours before your flight. Have your confirmation number ready before you start, and plan to spend about 5-10 minutes completing the change from start to finish.

Making Changes Over the Phone and Special Circumstances

Southwest maintains phone lines specifically for reservation changes, which may be necessary if you lack internet access or prefer speaking with a representative. The airline's phone system routes callers to reservation agents who can discuss your travel needs and help identify suitable flight options. Phone numbers appear on Southwest's official website, and representatives are available during business hours across all time zones.

When calling to change a flight, have your confirmation number, passenger name, and desired change information ready. The representative will pull up your reservation and explain what flights are available on your requested date. If you're uncertain about your new flight plans, the agent can discuss options and explain how the change affects any applicable credits or fare differences.

Special circumstances sometimes require phone assistance even if online tools are available. Passengers traveling with infants, passengers with mobility considerations, or those with complex multi-city itineraries may find phone support more effective. Additionally, if you're changing a flight within 24 hours of departure, certain restrictions may apply, and a phone agent can explain your specific situation.

Group bookings—reservations with multiple passengers under different names—generally require phone assistance to modify. If you booked travel for several family members as separate reservations, each one needs individual changes through their own confirmation number. Southwest's agents can coordinate changes across multiple reservations to ensure your group travels together on the new flight.

Military personnel, senior passengers, and those with disabilities should mention their status when calling, as representatives may have additional information about programs or considerations that apply to their travel. While Southwest doesn't charge change fees for these groups, understanding what other services or accommodations might be available is worth confirming during your call.

Practical Takeaway: Reserve phone calls for situations where online changes don't work or your booking situation is complex. Wait times are typically shortest during non-peak hours (early morning or late evening) and on weekdays rather than weekends.

Understanding Fare Differences and Travel Credits

When you change your Southwest flight, the new flight may cost more or less than your original booking. Southwest's system automatically calculates this difference based on the fares available at the time you make the change. Understanding how these fare differences work prevents confusion and helps you make informed decisions about whether to change your flight.

If your new flight costs less than your original booking, Southwest issues you a travel credit for the remaining amount. For example, if you originally paid $250 for a flight and change to a flight priced at $180, you receive a $70 travel credit. This credit never expires during your lifetime as a Rapid Rewards member, though non-members lose credits one year from the original booking date. You can apply the credit to any future Southwest booking, whether you're traveling yourself or using it for someone else's flight.

If your new flight costs more than the original booking, you'll need to pay the difference before the change processes. This additional payment can be made with any payment method Southwest accepts—credit cards, debit cards, or Rapid Rewards points if you have sufficient funds in your account. The system will not process your change request until payment for the fare difference is received.

Fare prices fluctuate throughout the day and vary by day of the week and time of year. The most expensive fares typically appear for flights departing during peak travel times (early morning and evening) on Fridays and Sundays. The least expensive fares usually appear for midweek flights during off-peak seasons. When you're changing your flight to a different date or time, checking multiple options can help you find the best fares available.

Travel credits apply only to Southwest-operated flights and cannot be transferred to other airlines. However, if you have a credit and Southwest changes or cancels your original flight, you may have additional options, such as rebooking on a partner airline or requesting a refund instead of a travel credit. The terms depend on Southwest's cancellation policies at the time the change occurs.

Practical Takeaway: Before paying a fare difference, check whether changing to a different date or time on the same route might cost less. Sometimes shifting your travel by a day or a few hours opens up significantly cheaper options, reducing or eliminating the fare difference you need to pay.

Timing Considerations and Advance Notice Requirements

Southwest allows changes to flights without fees, but the timing of your change request affects which options are available to you. Understanding how timing works helps you plan changes strategically and know what to expect based on when you make your request.

Changes made well in advance of your flight—typically more than two weeks before departure—present the widest range of options. Early changes allow Southwest's system to adjust seating and planning without operational complications. If you know your
