Southwest cancelled or delayed my flight — what do I do, and what am I owed?
Southwest disruptions come with one crucial twist: Southwest does not interline. It cannot — and will not — put you on another airline when its own flights are full. So when Southwest cancels or badly delays your flight, your only rebooking options are Southwest's own remaining seats, which fill fast, or a cash refund plus a ticket you buy yourself on another carrier.
Here's the playbook that accounts for that: how to grab the earliest confirmed Southwest seat, when to cut your losses and take the refund, and exactly what Southwest owes you for the disruption.

1. Rebook on Southwest immediately — app first
Southwest lets you self-rebook onto any remaining seat with no change fee, and the app is usually the fastest way to do it before the phone queue clogs. Because Southwest can't move you to another carrier, its own seats are all you've got from them — so grab the earliest confirmed one the moment the cancellation posts. Work the app and the phone line together and take whichever confirms first.
2. Claim your automatic DOT cash refund
If Southwest cancels, or significantly changes your flight (a domestic delay of 3+ hours), you can decline the new schedule and take a full cash refund to your original form of payment — not just Travel Funds. Southwest must pay it within 7 business days for cards, 20 days otherwise. This matters even more on Southwest: the refund is what funds the ticket you may need to buy on another airline.
3. Buy your own seat on another carrier if Southwest is full
Since Southwest won't endorse you elsewhere, if its remaining flights are days out, your fastest way home is often a new ticket on another airline. Take the DOT cash refund for the unused Southwest flight, then book the alternate directly. Reroute's search is built for exactly this — it prices the whole market, not just Southwest.
4. Get a hotel and meals if stranded overnight
When the cancellation is within Southwest's control (mechanical, crew, IT) and you're stuck overnight, Southwest's Customer Commitment covers reasonable hotel, meal, and transport costs. Ask at the desk, screenshot the offer, and keep receipts if you have to pay yourself and claim it back.
5. Rebook and claim in parallel
Getting home and getting your money back are separate tracks. Lock in a seat first — Southwest's or someone else's — then file the refund and any expense claims. Don't wait on the refund to start moving.
Get home for $24 — even if it's not on Southwest
Because Southwest won't rebook you on another airline, you have to find that seat yourself. Paste your cancelled or delayed Southwest itinerary and the time you need to land, and Reroute scans every carrier flying your route — Southwest and everyone else — then hands you a ranked recovery plan in minutes. The free search shows your options instantly; the $24 plan gives you the full ranked itinerary to book right now.

Frequently asked questions
- Will Southwest put me on another airline if it cancels?
- No. Southwest does not interline or codeshare, so it cannot endorse your ticket to another carrier. Your options are a remaining Southwest seat or a full cash refund you can use to buy a ticket on another airline yourself.
- Does Southwest owe me a cash refund, or just Travel Funds?
- Under the DOT automatic refund rule, a Southwest cancellation or significant delay entitles you to a full cash refund to your original form of payment if you choose not to travel — you do not have to accept Travel Funds or a credit.
- What does Southwest owe me if I'm stranded overnight?
- When the disruption is within Southwest's control and you're stuck overnight, its Customer Commitment covers reasonable hotel, meal, and ground transport costs. Ask at the desk and keep receipts if you pay out of pocket.
- How long does Southwest take to issue a refund?
- Under the DOT rule, Southwest must issue refunds within 7 business days for credit card payments and 20 calendar days for other methods, to your original form of payment.
