What Happens to Existing Southwest Reservations?

📞 +1-773-340-8614Existing reservations are not automatically treated as brand-new bookings simply because Southwest changed its seating system. Your specific reservation and fare determine what seating options are available.

📞 +1-773-340-8614If you previously booked and now see a seat-selection option, review the reservation carefully before making any changes.

Choice

Standard

What Happens With a Basic Fare?

📞 +1-773-340-8614Basic has the most limited seat-selection rules.

📞 +1-773-340-8614Southwest says Basic customers generally receive a Standard seat assignment at check-in rather than choosing a seat during booking. Check-in opens 24 hours before the original scheduled departure. If a seat cannot immediately be assigned, the customer may receive the assignment at the gate.

📞 +1-773-340-8614If you have a Basic reservation and want to understand whether you can obtain a different seat, 📞 +1-773-340-8614.

Can I Purchase a Better Seat After Booking?

📞 +1-773-340-8614Yes. Southwest says customers with eligible reservations can purchase available Extra Legroom, Preferred, or Standard seats after booking. Seat sales currently end 60 minutes before domestic departure and 90 minutes before international departure.

📞 +1-773-340-8614This means you do not necessarily have to make a new flight reservation just because you want a different seat.

What Happens If I Change My Southwest Flight?

📞 +1-773-340-8614Changing your flight can also change your seat situation.

📞 +1-773-340-8614When you move to another flight, the available seats on that new aircraft may be different from those on your original flight. If you purchased a seat separately, Southwest has specific exchange rules depending on whether the replacement seat costs the same, less, or more.

Will My Seat Automatically Transfer to the New Flight?

📞 +1-773-340-8614You should not assume that your original seat will remain identical after a flight change.

📞 +1-773-340-8614A different flight can have different seat availability, aircraft configuration, or seat categories. If you change flights, review the new reservation and seat assignment before traveling.

📞 +1-773-340-8614If your seat disappeared after changing your itinerary, 📞 +1-773-340-8614.

For general rebooking support, 📞 +1-773-340-8614.

Can I Change My Assigned Seat?

Yes, Southwest currently allows eligible customers to change their assigned seat through Southwest.com or the Southwest app.

For domestic flights, eligible seat changes can generally be made up to 60 minutes before the original scheduled departure. For international flights, the current cutoff is generally 90 minutes before the original scheduled departure. Availability and fare restrictions apply.

If you want to move from Standard to Preferred or Extra Legroom, the applicable seat price may be displayed.

For help checking your available seat choices, 📞 +1-773-340-8614.

What If Southwest Changes My Seat?

Airline operational changes can sometimes affect seat assignments.

Southwest's current seat-refund policy specifically addresses situations where the airline moves a customer from a higher seat category to a lower category. For example, if Southwest moves you from Extra Legroom to Preferred or Standard, or from Preferred to Standard, the airline says it will refund the original seat purchase to the original form of payment.

If your assigned seat changed unexpectedly, 📞 +1-773-340-8614.

What If My Flight Is Changed or Canceled?

A schedule change or cancellation can affect both your flight and your seat.

If Southwest significantly changes or cancels your flight, review the replacement itinerary and available seat assignment. If you decide not to travel because of a qualifying significant disruption, Southwest's current policy may provide a method-of-payment refund, including for eligible separately purchased seats.

If your flight was changed by Southwest, 📞 +1-773-340-8614.

If your replacement flight does not work for you, 📞 +1-773-340-8614.

Can I Change My Seat on the Same Day?

Southwest's assigned-seat system still provides same-day change and standby options for eligible fares.

Current Southwest rules state that eligible Choice, Choice Preferred, and Choice Extra customers can use same-day change when requirements are met. The replacement must generally be on the same calendar day and between the same origin and destination.

If you are trying to move to another flight today, 📞 +1-773-340-8614.

If you have already changed your flight and need to review the seat on the new itinerary, 📞 +1-773-340-8614.

What Happens to My Seat If I Use Same-Day Standby?

Same-day standby does not guarantee a seat on the requested flight.

If you are cleared onto another flight, your seat situation will depend on the available seating and the applicable rules. Southwest also states that a separately purchased seat on the original flight can be non-refundable when a customer uses same-day standby and is cleared.

For questions about same-day standby and your reservation, 📞 +1-773-340-8614.

Does Assigned Seating Affect Families?

Yes, but it also gives families an opportunity to select seats before traveling.

Southwest encourages families traveling on Choice, Choice Preferred, or Choice Extra fares to select adjacent seats when booking. If adjacent seats are unavailable, customers can check again later, subject to availability.

Basic-fare customers receive seats at check-in, so families traveling on Basic should check in as early as possible and review their assignments.

If you are traveling with children and want to review available seating options, 📞 +1-773-340-8614.

Does the New Seating System Change Boarding?

Yes.

Southwest also replaced its traditional A/B/C boarding positions with a new boarding structure using Groups 1 through 8. Boarding priority can depend on fare type, seat type, status, and other benefits.

For questions about your boarding group, 📞 +1-773-340-8614.

If you cannot find your reservation or assigned seat, 📞 +1-773-340-8614.

If your reservation changed after booking, 📞 +1-773-340-8614.
