10 Best Southwest Approved Pet Carrier 2026 in the United States

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 Sleepypod Air in-cabin pet carrier is a solid choice for travelers flying with small to medium pets weighing up to about 17.5 pounds (8 kg). It’s designed to be airline-friendly, including Southwest, meeting size limits with its compact 22 x 10.5 x 10.5-inch dimensions that can compress smaller for easier storage. The carrier is made from durable, luggage-grade nylon on the outside, which offers good protection, and soft Ultra Plush polyester inside for your pet’s comfort.

Ventilation is decent thanks to mesh panels on the top and ends that also make it easy to access your pet. Security is handled by sturdy zippers, and the adjustable padded shoulder strap adds convenience for carrying through airports or on short walks. It also doubles as a cozy bed with machine washable bedding, making overnight stays more comfortable for your pet. However, some users might find it a bit heavy at 4.5 pounds compared to other soft carriers. While ventilation is adequate, it’s not heavily ventilated like some mesh-only carriers, so it might be less ideal in very hot climates.

This carrier represents a thoughtful and versatile option if you want a stylish, airline-approved carrier that’s comfortable for your pet and manageable for you during travel.

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.
