10 Best Southwest Approved Pet Carrier 2025 in the United States

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 Sleepypod Air In-Cabin Pet Carrier is a solid choice for travelers needing a Southwest-approved carrier for small pets up to about 17.5 pounds. Its size is thoughtfully designed to meet airline requirements while still providing enough room for your pet to sit or lie down comfortably. The carrier features a sturdy nylon exterior combined with soft Ultra Plush polyester inside, which adds comfort and a cozy feel for your pet. It’s clever that the carrier can compress in height to save space when not in use, making storage easier.

Ventilation is handled well with mesh panels that let fresh air in while allowing your pet to see outside and feel less confined. Security is taken seriously through strong zippers and a padded shoulder strap, which helps you carry your pet safely and comfortably. The carrier also opens from the top and ends, making it simpler to get your pet in and out without stress. One of its strengths is the machine-washable plush bedding, which keeps things clean and fresh during travel. Large zipper pockets on both sides give you handy storage for treats or documents.

This carrier might feel a bit narrow for pets near the upper weight limit, and while it’s lightweight for its size, some might find 4.5 pounds a little heavy compared to other soft carriers. It is ideal for small dogs and cats who travel frequently by air or car and whose owners value comfort and security. Its durable materials and thoughtful features make it a reliable option, especially if you want a carrier that doubles as a pet bed. For pets on the larger side or if you need something ultra-light, comparing other models might be beneficial.

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.
