10 Best Southwest Approved Pet Carrier 2026 in the United States

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.

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 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.
