10 Best Southwest Approved Pet Carrier 2025 in the United States

The Petskd Top-Expandable Pet Carrier is designed to meet the specific size requirements of Southwest and Allegiant Airlines, making it a solid choice if you need a soft-sided carrier that fits under the airplane seat. Its dimensions (19 x 13 x 9 inches, expandable by 3.5 inches in height) are suitable for small dogs under 12 lbs and cats under 15 lbs, but you should measure your pet carefully since size matters more than weight for a proper fit. Ventilation is a strong point here, with mesh panels on five sides and three separate openings to provide airflow and visibility, helping keep your pet comfortable and calm during travel. The mesh is upgraded to resist tears from claws, which adds durability and safety.

The materials used are waterproof, scratch-resistant polyester with structural support from metal and fiber rods to prevent sagging or collapsing—this means the carrier holds its shape well and protects your pet. Security features include double zippers and a built-in leash attachment to keep your pet safely inside, which is reassuring for travel. The carrier also includes wheels, which make it easier to move around airports or other travel spots without heavy lifting. However, at over 7 pounds, it might be a bit heavy for some users to carry for long periods. Additionally, this carrier is ideal only for small pets—larger dogs or cats won’t fit comfortably.

Cleaning and storage are straightforward, and the brand offers a 12-month warranty, which suggests confidence in product quality. If you’re looking for a reliable, airline-approved option for small pets that balances comfort, security, and ease of use, this Petskd carrier is worth considering.

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 Petskd Top-Expandable Pet Carrier is a soft-sided, airline-approved carrier designed mainly for small cats and dogs under 10-12 pounds. Its dimensions (18x13x9.5 inches, expandable by 3.5 inches in height) fit Southwest Airlines’ under-seat space requirements, making it a reliable choice for travelers with small pets. The carrier offers excellent ventilation with mesh panels on five sides, allowing pets to see out and stay comfortable during trips. The mesh is upgraded to be scratch-resistant, helping prevent pets from damaging it or escaping.

Made from waterproof and durable polyester, the carrier is both sturdy and easy to clean, with machine washable options. For security, it features locking zippers, a built-in adjustable leash clip to keep pets safely inside, and a reinforced frame that prevents sagging or collapse. The carrier is lightweight at about 2.9 pounds and has multiple openings with non-slip zippers, which makes access and cleaning convenient.

This size is perfect for very small pets, though larger or heavier animals won’t fit comfortably. Also, because it’s soft-sided, it might not offer as much protection as hard carriers if your pet is very anxious or moves a lot. For frequent Southwest travelers seeking a carrier that fits airline rules while keeping small pets secure, ventilated, and reasonably comfortable, this model is a solid pick.
