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 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 Petmate Two-Door Plastic Pet Crate is a solid choice for small dogs or cats weighing up to 15 pounds, measuring 24 inches in length. Its size allows pets to comfortably stand, turn, and lie down, which is important for stress-free travel. Ventilation is well-handled with multiple holes providing fresh air and good visibility from all sides, helping pets feel less confined.

Made of durable plastic, the crate is easy to clean and includes a stay-dry moat that helps keep your pet dry by directing fluids away. The two doors—top and front—offer versatile and easy access, while steel doors with simple latches add security and peace of mind. A foldable handle enhances portability, making it convenient for travel, particularly since it meets most airline cargo requirements. Comfort-wise, there’s space to add a cushion, which is not included but can improve your pet’s experience.

The plastic construction, while sturdy, might feel somewhat rigid compared to soft-sided carriers. Assembly is required but straightforward, and the crate's weight of just over 5 pounds keeps it manageable. This kennel is ideal for pet owners who need a reliable, secure, and airline-approved carrier for small dogs or cats and want something easy to maintain and transport. It may be less suitable if you prefer more plush or flexible materials or if your pet exceeds the size or weight limits.
