Yes, car seats do not count as your standard checked baggage allowance on Southwest Airlines. You can check one child restraint seat (car seat) and one stroller per child for free, in addition to your two free checked bags. This is a significant benefit for families traveling with young children. The key is to declare them as "child restraint devices" at the curb-side check-in, the ticket counter, or the gate.
To ensure a smooth process, it's highly recommended to use a protective bag. While Southwest handles these items with care, a bag protects against dirt and minor damage during transit. You can check them at the ticket counter or, more conveniently, at the gate. Gate-checking allows you to use the car seat and stroller right up until you board the plane, and it will be returned to you as you disembark.
There are no specific weight limits for car seats themselves, but they must be used for a child and should be a standard, commercially manufactured model. Booster seats are also included in this policy. For oversized car seats or if you're traveling with an excessive number, it's always best to contact Southwest directly to confirm.
Here is a quick summary of the policy:
| Item | Count Allowed | Fee? | Check-in Options | Special Notes |
|---|---|---|---|---|
| Car Seat (Child Restraint) | 1 per child | Free | Ticket Counter, Gate | Must be for a child; use a bag for protection. |
| Stroller | 1 per child | Free | Ticket Counter, Gate | Gate-check is highly convenient. |
| Standard Checked Bag | 2 per passenger | Free (conditions apply) | Ticket Counter, Curb-side | Standard size/weight restrictions apply. |
This policy makes Southwest one of the most family-friendly airlines in the U.S., removing a major financial worry for parents.

As a mom of two, I always fly Southwest for this reason. The car seat and stroller fly free, no questions asked. I always gate-check them. It’s a lifesaver—the kids are in the stroller through the airport, and I get the car seat back right when I step off the plane. Just make sure to get a gate-check tag from the agent at the departure gate. I use a cheap travel bag from Amazon to keep everything clean.

From a purely practical standpoint, the answer is yes, they are exempt from baggage fees. The policy is outlined clearly on Southwest's website under "Traveling with Children." The critical distinction is labeling them correctly as "child restraint devices" rather than standard luggage. This designation is what triggers the fee waiver. Ensure the items are in good condition to avoid any issues during the baggage screening process.
