Southwest Airlines Same-Day Change Policy:
Complete Guide
Southwest genuinely has some of the most generous same-day flexibility in the industry — but there's a common misconception worth clearing up first: free same-day standby is not actually available to everyone on a Basic fare, despite what a lot of general guides claim. Southwest's own published policy is specific about who really qualifies, and it's narrower than most people assume.

Same-Day Change: Free, But Not on Basic
On the day of travel, Southwest lets you switch to another flight — space available — departing on the same calendar day, between the same origin and destination airports as your original flight, with no airline change fee. You'll only owe any government taxes and fees tied to the new itinerary, and those are refunded if none are actually required.
This benefit is limited to Choice, Choice Preferred, and Choice Extra fares. Basic fares are not eligible for free same-day change at all — you'd need to upgrade to Choice or higher before you could use it, the same restriction that applies to standard flight changes on Basic more broadly.
Same-Day Standby: Who Actually Qualifies
This is where a lot of general advice online gets it wrong. Southwest's own fare information page is specific: with the exception of A-List Preferred and A-List Rapid Rewards Members, customers who purchase Basic fares are not eligible for free same-day standby either.
A common claim floating around is that same-day standby is available to all Southwest passengers regardless of fare, with only same-day confirmed change restricted to higher fare tiers. That's not what Southwest's own policy says. If you're on a Basic fare and don't hold A-List or A-List Preferred status, you generally need to upgrade your fare to access standby too — not just confirmed same-day change.
If you do hold A-List or A-List Preferred status, you get a genuine carve-out: standby is available to you even on a Basic fare. Free same-day change, though, still requires a qualifying fare — elite status alone doesn't unlock that specific benefit.
The Timing Cutoffs You Need to Know
| How you're making the request | Cutoff |
|---|---|
| In person at the airport | At least 10 minutes before your original flight's scheduled departure |
| Southwest app, mobile web, or phone — domestic flights | At least 60 minutes before the new flight's scheduled departure |
| Southwest app, mobile web, or phone — international flights | At least 90 minutes before the new flight's scheduled departure |
Miss the applicable cutoff and Southwest's no-show policy may apply instead, which is a meaningfully worse outcome than a same-day change.
What Happens to Your Money and Your Bags
If you're changing via the app, website, or phone and your new seat costs more than your original one, you pay the full price of the new seat and are automatically refunded for the original. If you make a same-day change in person at the airport instead, the seat you originally purchased is non-refundable. Either way, your original seat and boarding position aren't guaranteed once you make the change.
Checked bags deserve a specific mention: if you're cleared for a standby flight, you may be separated from your bags. They could still arrive on your original flight rather than the one you actually board — Southwest is only responsible for delivering bags on the flight they were originally checked onto, so plan accordingly if you're checking a bag and hoping to catch an earlier flight via standby.
Who Can't Use Same-Day Change or Standby
- Partner itineraries — flights booked in combination with a partner airline generally aren't eligible for same-day change.
- Group bookings — not eligible for same-day standby.
- Unaccompanied minors — not eligible for same-day standby.
- International standby listings — may require speaking with a Customer Service Agent directly rather than using self-service options.
