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 Sherpa Original Deluxe Travel Pet Carrier is a solid choice for pet owners looking to travel comfortably with small to medium pets, especially by air. Its size (17" x 11" x 10.5") fits pets up to 16 pounds, making it suitable for cats and small dogs. The carrier’s standout feature is its airline approval and Guaranteed On Board program, designed to meet most major airlines’ requirements, including Southwest. The patented spring wire frame allows the carrier’s rear to compress easily under airplane seats, which is a practical plus for in-cabin travel. Ventilation is well-covered through mesh panels on multiple sides, ensuring your pet gets plenty of fresh air during trips. The material, mainly polyester, is durable and the waterproof interior base adds protection against accidents. For comfort, the removable, machine-washable cozy liner is a nice touch, helping keep pets cozy and the carrier clean.

Security is addressed by escape-proof locking zippers, giving peace of mind that pets will stay safely inside. The carrier is also versatile with top and side openings for easy loading and unloading. Carrying options include a padded handle or a detachable shoulder strap, which is convenient for different travel situations. Additionally, the carrier doubles as a soft-sided crate for vet visits or other outings and even includes a luggage strap that can secure it during car rides. On the downside, the size and weight limit mean it isn’t suitable for larger pets, and spot cleaning is recommended rather than machine washing the whole carrier. Also, while the design is functional, it’s fairly basic and may not offer extra padding or luxury features found in some other carriers.

This Sherpa carrier provides a dependable and practical option for small pets and travelers needing an airline-friendly, comfortable, and secure carrier that’s easy to handle.

The Petmate Pet Porter Fashion Dog Kennel is a solid choice for small to medium dogs weighing between 15-20 pounds, matching Southwest Airlines' pet carrier requirements well due to its airline-friendly size and design. Measuring about 24 by 16.5 by 14.5 inches, it offers enough room for your pet to stand, turn around, and lie down comfortably, which is key for your furry friend’s comfort during travel. Ventilation is thoughtfully included on four sides, ensuring good airflow and visibility, so your pet can breathe easily and stay calm. The durable plastic shell makes this carrier sturdy and easy to clean, which is especially handy in case of accidents during trips. Inside, a stay-dry moat helps keep your pet dry by directing fluids away.

Security is addressed with a strong wire door and easy-open latch that keeps your pet safely inside while allowing quick access when needed. The fold-down handle adds convenience by making the carrier easier to carry. Assembly requires no tools, making it user-friendly for anyone. It also has a small built-in storage spot for essentials like treats or ID tags, which is a nice touch for travel convenience.

On the downside, at around 4.5 pounds, it’s a bit heavier than some soft-sided carriers, which might be less comfortable if you plan to carry it for long periods. The hard plastic design, while protective, may not be as flexible or packable as soft carriers. This carrier provides a good balance of safety, comfort, and practicality for pet owners needing a reliable, airline-approved option for their small dogs.
