Overview: Can You Fly With a Cat on Southwest
If you are planning a trip and searching for "southwest flying with a cat," you likely want a clear, practical summary of what to expect. Southwest Airlines allows small, carrier‑qualified cats in the cabin as carry‑on bags, provided they fit under the seat, remain calm, and meet health and documentation standards. This guide covers policy details, costs, required preparations, alternatives if your cat does not qualify, and tips to reduce stress for you and your cat, helping you move through the airport and flight with confidence.
Southwest In‑Cabin Pet Policy at a Glance
Southwest treats cats in the cabin as carry‑on items that must fit within a soft‑sided or hard‑sided carrier and stay under the seat throughout boarding. You cannot check a cat in the cargo hold, and each passenger is generally limited to one pet in the cabin. Cats must be healthy, house‑trained, and quiet enough not to disturb other travelers. Service animals have different rules; this policy applies to cats traveling as companion pets in the cabin only.
Key Requirements You Must Meet
Carrier and Fit
The carrier must be airline‑approved and remain under the seat in front of you. Soft carriers are common, but hard carriers are allowed if they meet size rules. Measure your cat plus carrier together: typical internal dimensions are approximately 18–20 inches long, 11–12 inches wide, and 10–12 inches tall, but always verify current limits on Southwest’s website or with phone support.
Health and Age
Your cat should be healthy, at least 8–10 weeks old, weaned, and free of contagious conditions. A veterinarian exam within 10 days of travel is strongly recommended to confirm fitness for flight. Kittens must be fully weaned; pregnant cats or those with respiratory conditions may face higher risk and additional restrictions.
Behavior and Noise
Cats must be well‑behaved enough to remain in the carrier without causing a disturbance. Excessive vocalization or attempts to escape can lead to denial of boarding. Practice short carrier trips before the day of travel to gauge how your cat responds to motion and proximity to other passengers.
Required Documents and Proof
While Southwest does not require a health certificate for domestic flights within the United States, you should be ready to show proof of identity for your cat if asked, such as a tag, microchip information, or recent photo. If you are flying to or through a destination with specific entry rules (e.g., Hawaii or international locations), additional documentation may apply, so verify local requirements in advance.
Costs and Booking Process
Southwest charges a pet fee each way for each cat in the cabin. Fees are typically due during booking and can often be paid online or at the gate, though availability and exact charges may vary. The cat counts toward your standard checked bag allowance only in the sense that it occupies personal space under the seat; it does not substitute for a checked bag you might also need. Always confirm current fees and policies when you book, especially during peak seasons or promotional periods.

Day of Travel: What to Expect
Arrive at the airport with extra time to manage check‑in and security. Keep your cat in the carrier during ticketing, in the security lane, and at the gate. Inform the ticket agent that you are traveling with a cat so they can note it in your boarding record. Be prepared for brief inspections at security, and follow agent instructions to avoid delays. During boarding, proceed calmly and ensure the carrier is secured under the seat before takeoff.
Alternatives If Your Cat Does Not Qualify
If your cat is too large, unwell, or disruptive, Southwest may require you to find another option. Consider traveling with an approved carrier that meets size limits, scheduling a trip when your cat is more settled, or using a professional pet transport service for longer or more complex routes. In some cases, adjusting your travel dates to a less busy time can improve your experience. For animals that cannot meet cabin requirements, checking policies for other airlines or planning road trips may be necessary.
Stress Reduction and Safety Tips
- Acclimate your cat to the carrier with multiple short sessions before travel.
- Use a familiar blanket or toy to provide comfort and reduce anxiety.
- Avoid feeding large meals right before departure to lessen motion sickness risk.
- Consult your veterinarian about mild calming options if your cat is highly stressed.
- Keep your cat’s carrier closed and secure at all times in the cabin.
