Southwest is the only major carrier with two free checked bags. That generosity comes with a silver lining when things go wrong.
Two free bags means there’s no fee to refund — but it also means Southwest handles more checked luggage per passenger than almost any competitor. Despite that volume, Southwest’s 0.42% mishandling rate beats all three legacy carriers. And because Southwest runs a point-to-point domestic network, your bag is almost always somewhere within the continental U.S. system, which simplifies recovery.

How to Report Lost Baggage with Southwest
Report at the Baggage Service Office immediately
Go directly to the Southwest Airlines Baggage Service Office at the airport before leaving. Bring your baggage claim ticket and photo ID. The agent will file a report in WorldTracer and give you a reference number — that’s the single most important piece of paper you’ll walk away with. Southwest’s policy requires immediate reporting at the airport, so don’t head home first. [1]
File your claim online or by phone
Visit Southwest’s baggage help page to complete a delayed baggage claim, or call 1-800-435-9792 for assistance. Enter your flight details, a detailed bag description (color, brand, size, distinguishing features), and your delivery address. The Southwest app also accepts claims. [2] [6]
Track your bag and wait for delivery
Use your reference number to check the status of your bag online or by calling Customer Relations. Because Southwest’s network is overwhelmingly domestic, your bag is almost certainly still in the U.S. system — there’s no international transfer to complicate things. Most delayed bags are located within 24-48 hours. When found, Southwest delivers it to your local address at no charge. [2]
Compensation and Policy Details
Liability Limits
Southwest Airlines’ maximum liability for lost, delayed, or damaged checked baggage is $4,700 per ticketed passenger on domestic flights, per 14 CFR Part 254. [4] For Southwest’s limited international routes, flights governed by the Montreal Convention carry a cap of 1,519 SDR (approximately $2,025 USD). [1]
Compensation is based on depreciated value, not replacement cost. Receipts, bank statements, and photographs strengthen your claim. For a complete breakdown of your federal rights, see our airline baggage compensation guide.
Interim Expenses
While your bag is delayed, Southwest reimburses reasonable interim expenses for essential items — clothing, toiletries, and necessities. [2] There’s no published daily cap. Hang onto every receipt and submit claims promptly. No federal law mandates a specific daily dollar amount; the standard is “reasonable and verifiable.”

|---|---|
| Report delayed bag | Immediately at airport |
| Report damaged bag | Within 4 hours of arrival |

Southwest’s strong performance is notable given its volume: with two free checked bags, Southwest handles more bags per passenger than carriers that charge fees. The airline’s point-to-point network also means fewer transfers — and transfers are where most bags go astray. See how all airlines compare in our complete airline rankings.
Traveler Tips for Southwest
Two free bags doesn’t mean skip the tracker
Southwest’s free bag policy encourages passengers to check more luggage. More checked bags means more exposure to mishandling. Consider placing a Bluetooth luggage tracker in each bag, especially on busy travel days like holiday weekends when Southwest’s system runs at capacity.
Report before you walk out the door
Southwest requires immediate reporting for delayed bags. The Baggage Service Office is your first stop. Once you leave the terminal, you can still file by phone or online, but in-person reporting generates the fastest response.
Photograph your bag before every trip
Take a photo of the exterior and a quick snapshot of the contents. Southwest agents need a detailed description to locate your bag in WorldTracer. A photo speeds up identification and supports your claim if the bag is declared lost. It’s a 10-second habit that pays for itself.
Use Rapid Rewards status
If you have Rapid Rewards A-List or A-List Preferred status, mention it when filing your report. Priority handling can accelerate bag recovery through dedicated support channels. It won’t guarantee a faster outcome, but it doesn’t hurt.
Leverage Southwest’s Customer Service Action Plan
Southwest publishes a Customer Service Action Plan that outlines its commitments during service disruptions, including baggage delays. [5] If your claim is moving slowly, reference this plan when escalating. It gives you a framework for what the airline has promised to deliver — and customer service reps know you’ve done your homework.
