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 Petskd Top and Side Expandable Pet Carrier is designed specifically for small pets (dogs under 10 lbs and cats under 12 lbs) and meets Southwest Airlines’ under-seat size requirements. Its folded dimensions (18x13x9.5 inches) make it a good fit for traveling on Southwest and some other airlines, which is great if you need a reliable, approved carrier. It offers excellent ventilation with mesh panels on five sides, helping your pet stay cool and allowing you to keep an eye on them during travel. The carrier is made of durable, waterproof polyester with reinforced mesh to resist scratching and prevent escape, which adds peace of mind and longevity to the product.

Comfort-wise, it features an expandable top and side sections that increase space by about 80%, letting your pet sit, stand, or stretch when not restricted by airline rules. Security is well addressed with locking zippers, a collar buckle, and a sturdy frame that prevents sagging or collapsing. The carrier also includes practical extras like a shoulder strap and washable mats, making it easy to carry and clean.

This carrier is suitable only for very small pets, which limits its use if you have a larger animal. Also, you need to fold down the expandable parts during flights to meet size restrictions, which reduces space for your pet at that time. Pet owners flying Southwest with small dogs or cats will find this carrier a safe, breathable, and airline-compliant travel option.

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.
