10 Best Southwest Approved Pet Carrier 2025 in the United States

The Katziela Pet Carrier is designed as a small, soft-sided carrier that meets airline and TSA approval, making it suitable for travelers who need a reliable way to bring small dogs or cats onboard. Its dimensions (about 19 x 13 x 15 inches) fit well within common airline size restrictions, and the lightweight nylon material helps keep it easy to carry. One of its standout features is the excellent ventilation provided by mesh windows on the top and sides, allowing your pet to see outside and stay cool, which is great for reducing travel stress.

Comfort is taken into account with a soft interior and an inner leash hook to keep pets secure, while the shoulder strap and six wheels add convenience, giving you options to carry or roll the carrier depending on your preferences. Because it’s designed for small pets, it won’t be suitable for larger dogs. The structure may be less sturdy compared to hard carriers, and the nylon material may not offer as much protection against rough handling.

This carrier offers a good balance between comfort, ventilation, and portability for small pets traveling by air, especially if you value a lightweight, breathable design with rolling wheels for ease of movement.

The Petskd Top-Expandable Pet Carrier with Wheels is a versatile and convenient option for pet owners traveling with airlines like Southwest and Allegiant. It measures 18x13x9.5 inches, making it suitable for small pets. The carrier features mesh ventilation on five sides, ensuring your pet gets plenty of fresh air and you can easily check on them. The material used is waterproof and scratch-resistant polyester, providing durability and protection against wear and tear.

Comfort-wise, it offers a smooth travel experience thanks to its high-quality, 360° rotating wheels. These wheels can be removed, allowing the carrier to be used as a shoulder bag or handbag when needed. Security is well-addressed with locking safety zippers and a built-in adjustable rope buckle to keep your pet secure inside. The sturdy frame ensures the carrier maintains its shape and does not collapse.

One downside is the carrier's weight—7.05 pounds—which might be a bit heavy when carrying. Additionally, it's essential to check your pet's dimensions, as it is designed for small pets under 12 pounds. The carrier also comes with a 12-month warranty, which provides some peace of mind regarding its quality and durability. This carrier is best suited for those who frequently travel with small pets and need a reliable, airline-approved option that offers both convenience and security.

The Amazon Basics Hard-Sided Dog and Cat Kennel is a solid choice if you need a Southwest-approved pet carrier for small pets like cats or puppies. Its dimensions (23.6"L x 15.7"W x 13"H) provide a decent amount of space suitable for small to medium pets, though larger animals might find it cramped. The hard plastic body offers good durability and protection during travel, and the metal wire door and side panels allow for proper ventilation, helping keep your pet comfortable and cool. The locking door mechanism adds a layer of security, ensuring your pet stays safely inside. It also features a top handle, making it easier to carry through the airport or to your destination. However, since it has only one door (front entry), it might be a bit less convenient to place your pet inside compared to carriers with multiple access points.

Comfort-wise, the hard shell might not be as cozy as soft-sided carriers, so adding a soft pad or blanket inside is advisable. While it weighs about 5.3 pounds, which is manageable, the hard plastic construction might feel bulkier to some users. This carrier serves as a practical, reliable option for air travel with small pets, especially if you prioritize sturdiness and ventilation for your furry friend.
