Southwest Airlines lost your luggage? Here’s what to do
Summary: File a delayed-bag report at the Southwest baggage office before you leave the airport; the report number is what you quote on follow-up calls. When Southwest Airlines loses your bag you can claim reimbursement for the contents and for reasonable interim expenses — file before the deadline.
Why Southwest Airlines lost your luggage
- A bag was delayed, misrouted, or never arrived.
- Contents were missing or damaged on arrival.
Calling Southwest Airlines: what to expect
Southwest Airlines’s line is 1-800-435-9792; reservations and customer service are staffed around the clock.
To reach a person: say "existing reservation" or "cancellation" when asked why you are calling, then read your confirmation number when prompted, then say "representative" if the system keeps offering self-service options. Menus change — if yours does not match, say "representative" at any prompt.
Self-service runs through southwest.com / Southwest app (https://www.southwest.com); and you may see these names on your paperwork: Rapid Rewards, Southwest app, A-List.
Step by step: what to do
- File a property irregularity report with Southwest Airlines at the airport, before you leave.
- Keep receipts for essentials you have to buy while the bag is missing.
- Call Southwest Airlines at 1-800-435-9792 (say "existing reservation" or "cancellation" when asked why you are calling, then read your confirmation number when prompted, then say "representative" if the system keeps offering self-service options) to file the reimbursement claim and get a claim number.
- Submit an itemized list of contents and their value within the deadline.
Common mistakes to avoid

What to say when you call Southwest Airlines
- My checked bag was lost — I’m filing a reimbursement claim for the contents and my interim expenses.
Southwest Airlines-specific things to know
- File a delayed-bag report at the Southwest baggage office before you leave the airport; the report number is what you quote on follow-up calls.
- Southwest reimburses reasonable interim expenses on delayed bags; keep receipts and submit them with the claim.
- Southwest has no change fees, but "Wanna Get Away" fares are non-refundable when you cancel — you get flight credit; only Southwest-caused cancellations or refundable fares get cash back.
- Southwest flight credits no longer expire, so a credit is less of a loss than at other airlines — but a Southwest-caused cancellation still entitles you to cash.
- Southwest checks two bags free on most fares, which removes most baggage-fee disputes but not delayed- or lost-bag claims.
- Southwest cancellations show in the app with a "Refund" or "Rebook" choice; the phone lines are busiest right after a large disruption.
Know your rights
When an airline cancels or significantly changes your flight, DOT rules entitle you to a cash refund to your original form of payment — not just a travel credit — if you choose not to rebook.
Regulator: the U.S. Department of Transportation (DOT). If the airline stalls, file a complaint with the DOT Office of Aviation Consumer Protection and dispute the charge with your card issuer.
If Southwest Airlines will not move, the escalation paths that carry weight:
- Use the "Contact us" email form on southwest.com; Southwest customer relations answers in writing.
- File a complaint with the DOT Office of Aviation Consumer Protection.
- Dispute the charge with your card issuer if a refund owed under DOT rules has not arrived within 7 business days.

Frequently asked questions
How much can I claim for a lost bag?
For domestic U.S. flights, airline liability for lost checked bags is capped by DOT at a set maximum. Submit an itemized claim with receipts to recover up to that limit.
Do I get cash back from Southwest if I cancel a Wanna Get Away fare?
No — you get flight credit, which does not expire. Cash refunds are for refundable fares or for flights Southwest itself cancels or significantly changes.
Does Southwest charge for checked bags?
Southwest includes checked bags on most fares, so fee disputes are usually about oversize or overweight bags. Delayed or lost bags are a separate claim.
How do I reach a Southwest representative?
Say "representative" to the phone system, or use the app’s help chat, which is often faster after a disruption.
