10 Best Southwest Approved Pet Carrier 2025 in the United States

The Petskd Top-Expandable Pet Carrier is a solid option for travelers looking to bring their small pets on Southwest or Allegiant Airlines. Its dimensions (18x13x9.5 inches) are designed to fit comfortably under the seat, making it a great choice for pets weighing up to 12 pounds. One of its key strengths is the excellent ventilation; the mesh sides allow for airflow and visibility, so pets can enjoy the journey without feeling trapped. The structural design also stands out, with reinforced materials that prevent sagging and ensure stability, which is important for your pet's safety. Additionally, the locking zippers and adjustable rope buckle provide extra security to keep your pet safe during travel. The carrier is made from durable, waterproof polyester, which is vital for easy cleaning and longevity. Plus, it comes with a decent warranty, offering reassurance in case of any quality issues.

On the downside, the carrier is only suitable for small pets, which limits its appeal to pet owners with larger animals. It’s essential to check your pet's dimensions before purchasing, as not all small pets will fit comfortably. While the material is scratch-resistant, some users may find that the mesh can be vulnerable to sharp claws over time, despite it being upgraded to resist tearing. Also, the carrier being machine washable is a plus, but frequent washing could wear down the materials more quickly.

This carrier suits pet owners who travel frequently with small cats, dogs, or even rabbits, offering a comfortable and secure traveling experience. However, potential buyers should ensure their pets fit the specified size limits to avoid issues during travel.

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 Sherpa Original Deluxe Travel Pet Carrier is designed for pet owners needing a travel-friendly and Southwest-approved pet carrier. The patented spring wire frame is a notable strength as it allows the rear end to be easily compressed to fit under airline seats, a critical feature for air travel. Additionally, its mesh panels ensure good ventilation, keeping pets comfortable during trips. The carrier's material is durable polyester, and it includes escape-proof locking zippers, adding a layer of security for your pet.

The waterproof interior base and removable machine-washable liner make cleaning convenient. Comfort is enhanced with a padded top handle, a detachable shoulder strap, and a cozy base liner. This carrier is versatile, suitable for travel, vet visits, and regular outings with small dogs or cats. Its size is fairly large, accommodating pets up to 22 pounds, with ample storage pockets for pet accessories.

However, the polyester material, while durable, may not withstand heavy chewing or scratching. At 3.99 pounds, it is relatively lightweight but might feel bulky for petite users. Spot cleaning might also be less convenient than full washes for some owners. The one-year limited warranty is a reassurance of the product's quality but does not cover typical wear and tear or damage caused by pets. This carrier is best suited for pet owners who frequently travel or need a reliable and airline-compliant carrier for their small to medium-sized pets.
