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 Sherpa Original Deluxe Travel Pet Carrier in Charcoal Gray is a versatile and travel-friendly option for pet owners. Sized at 19 inches long, 11.5 inches wide, and 11.75 inches high, it fits pets up to 22 pounds, making it suitable for small dogs and cats. The patented spring wire frame allows the rear end to be pushed down to fit comfortably under seats, meeting the requirements for domestic rail and air travel, including Southwest Airlines. Ventilation is well-considered, with mesh panels ensuring plenty of air flow, and escape-proof locking zippers for added security.

The carrier’s comfort features include a removable and machine washable cozy base liner and multiple entry points for easy loading of your pet. It's made from durable polyester, providing a robust yet soft-sided crate that can double for vet visits and daily outings. The padded handle and detachable shoulder strap offer flexible carrying options, while the large storage pocket and luggage strap that also serves as a seatbelt pass-through add to its practical design.

However, some owners may find the carrier slightly bulky for very tight spaces, and the weight limit requires careful consideration to ensure your pet isn't cramped. If ease of use and comfort for both pet and owner are top priorities, this carrier is a solid choice.
