Can I Change My Flight Time On Southwest? | Same-Day Change Rules

Yes, Southwest lets you change flight times online or in-app; fare differences may apply, and same-day switches depend on your fare and open seats.

Plans shift. Meetings run long. A ride falls through. Southwest is usually easy to work with, as long as you know which type of time change you’re making and what it does to your total price.

This article breaks down what matters: changing to a new departure time days ahead, switching flights on travel day, using standby, and keeping track of fare differences and flight credits.

What A Flight Time Change Means On Southwest

On Southwest, changing your flight time usually means rebooking your reservation onto a different flight that fits your day. You keep the same confirmation number, but the flight number and departure time can change.

Two details drive almost every outcome:

  • When you change: Days ahead behaves differently than travel day changes.
  • Your fare and open seats: The fare type sets the rules, and seat inventory sets your choices.

If the new flight costs more, you pay the difference. If it costs less, Southwest typically issues the difference as flight credit tied to the traveler on the ticket. Track it in your account so it doesn’t get lost.

Can I Change My Flight Time On Southwest? Options That Fit Your Day

Yes. Most reservations can be changed online or in the Southwest app without calling. Southwest’s own guidance on changing trips notes that you can update a flight close to departure and that some fare products have limits. Southwest’s “Rebook or Change Trip” page covers the baseline rules.

You’ll pick one of these routes:

  • Standard change (before travel day): Move to any open flight time on a future date, paying any fare difference.
  • Same-day confirmed change (travel day): Swap to an earlier or later flight that same calendar day when a seat is open.
  • Same-day standby (travel day): List for an earlier flight and fly only if space opens near departure.

Same-Day Change Versus Same-Day Standby

These sound similar, but they behave differently at the airport and in your wallet.

Same-day confirmed change

A same-day confirmed change moves you to another flight on the same day with a confirmed place for boarding. Southwest says this option works when there’s an open seat and your origin and destination airports stay the same. Southwest’s “Same-day change & same-day standby” page lists the steps, plus the limits that trip people up.

Depending on the fare you bought, the airline charge can be $0 or you may pay the fare difference to confirm that seat. The payoff is certainty: you leave on the new flight you picked.

Same-day standby

Standby is a waitlist for an earlier flight on the same day. You keep your original flight as a fallback, then you clear into the earlier flight only if a seat opens near departure time. It’s a solid choice when you want to leave sooner and you can live with uncertainty.

What You Pay When You Change A Southwest Flight Time

Southwest doesn’t add a traditional “change fee” on many fare products. The main cost is the price difference between the flight you have and the flight you want. On a busy route, even a small time shift can jump in price.

Same-day options can change the math. Some fares include free same-day confirmed changes, while other fares show a price difference to lock in a guaranteed seat. If you don’t want to pay and you’re trying to move earlier, standby can be the no-cost path.

Fare Types And What They Allow

Your email receipt and your “Manage Trip” screen show what you bought, and that’s what the system uses when it decides what change options appear.

  • Higher-tier fares: More likely to include free same-day confirmed changes when seats are open.
  • Mid-tier fares: Changes usually work smoothly, and credits can be easier to handle.
  • Entry-level fares: May block changes unless you upgrade to a higher fare product.

Table: Change Options By Fare And Situation

Situation What You Can Do What You Pay Or Keep
Change days ahead to a new time Rebook to any open flight on your route Pay fare difference or receive flight credit if cheaper
Need a guaranteed new time on travel day Use same-day confirmed change on a flight with open seats $0 airline charge on eligible fares; others may pay difference
Want an earlier flight without paying List for same-day standby on an earlier departure No seat guarantee; original booking stays as fallback
Changing only one traveler on a group booking Select specific passengers during the change flow Credits and fare differences follow each traveler
Flight price drops after you book Change to the same flight again at the lower fare Difference becomes flight credit for the traveler
You changed your mind twice Change again if inventory still works for you New fare difference replaces the old one
Southwest changes your schedule Pick a new time offered in your reservation tools Often $0 if you stay within the airline’s allowed window
Using flight credit to pay Apply travel funds at checkout when changing Track remaining balance and any expiration date in your account

How To Change Your Flight Time In The Southwest App Or Online

If you can do the change yourself, that’s usually faster than phone help. The labels can shift with app updates, yet the flow stays familiar.

  1. Open the Southwest app or go to the website and sign in.
  2. Open your trip under Trips or Manage.
  3. Select Change or Change flight.
  4. Choose which traveler(s) to change if your reservation has more than one passenger.
  5. Select your new flight time and review the fare difference screen.
  6. Pay any difference, or confirm the flight credit details if the new fare is lower.
  7. Save your updated confirmation and note your new check-in timing.

How To Make A Same-Day Change Without Getting Tripped Up

Same-day changes tend to fail for three reasons: the flight is full, the airports don’t match, or the traveler taps the wrong option.

Check the airport pairing first

Southwest’s same-day rules are built around “same origin and same destination.” That can matter in metro areas with more than one airport. If you booked one airport and the flight you want uses the other, the same-day menu may not show it.

Pick certainty or flexibility

If you need a guaranteed seat, go with same-day confirmed change and accept any fare difference that shows. If you can wait and you only want an earlier flight, standby can do the job without a payment screen.

What Happens To Your Money When You Change

The flight itself is the easy part. The money piece is where people get annoyed, mostly because credits are easy to forget.

When the new flight costs more

You pay the difference at checkout. If you paid with a credit card, you can usually use a card again, then add any eligible travel funds you already have.

When the new flight costs less

Southwest typically issues the difference as flight credit for the traveler. Save it right away. Keep a note with the traveler name, the amount, and the confirmation number that created it.

Table: Common Time-Change Scenarios And A Clean Fix

Scenario Clean Fix Small Trap To Avoid
You want a later flight today Use same-day confirmed change if seats are open Late-day flights fill fast on popular routes
You want an earlier flight today Try standby first; confirm a seat if you need certainty Standby clears close to departure
You’re stuck in traffic to the airport Change to a later time as soon as you see the delay Waiting too long can put you at risk of a no-show
You found the same flight cheaper Change to the same itinerary again at the lower fare Credit stays with the traveler, not the cardholder
You’re traveling as a group, one person needs a new time Change only that traveler, then message the group Everyone won’t stay on the same confirmation
The app won’t load at the airport Try the website on airport Wi-Fi, then call if needed Take a screenshot of your confirmation
You want to change airports in the same city Do a standard change or rebook to the airport you want Same-day menus may not show a different airport pair
You changed once and plans shift again Change again while seats still exist Price can rise in the last day

Tips That Keep Changes Calm

These small moves reduce stress and wasted money.

  • Start with the flight list: Seeing seat availability makes the decision easier.
  • Grab the workable flight first: If seats still exist, you can refine later.
  • Save proof of the new itinerary: A screenshot plus the confirmation email covers you if signal drops.
  • Track credits the same day: If you can’t find them later, they won’t help you.

Final Pre-Travel List For A Smooth Time Change

Right before you hit “confirm,” run through this list:

  • Verify the airports match your original route on travel day.
  • Confirm which travelers you’re changing.
  • Check the fare difference screen twice.
  • Save the updated confirmation and note your check-in timing.
  • If a credit is created, record the amount and any expiration date shown in your account.
