10 Best Southwest Approved Pet Carrier 2026 in the United States

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.

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.
