10 Best Southwest Approved Pet Carrier 2025 in the United States

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.

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 ROVERLUND Airline-Compliant Pet Carrier is a suitable option for pet owners traveling by air, particularly with Southwest Airlines. It supports pets up to 20 lbs and complies with the in-cabin sizing of most major airlines, which is a significant advantage for frequent travelers. With three sides of ventilation, it ensures your pet gets plenty of fresh air during trips, enhancing their comfort. The carrier is constructed from marine and mountaineering grade materials, promising durability, and it comes with a one-year warranty for added peace of mind. However, pet-induced damage is not covered by the warranty.

A distinctive feature is its leak-resistant bottom, which is particularly useful for long journeys. The carrier also folds flat, making it convenient to store when not in use. Additionally, the shoulder strap can be converted into a leash, adding versatility.

On the downside, the carrier's weight at 3.2 pounds might be slightly heavy for some users, especially with a pet inside. Also, while it is designed to be durable, some users might find the material to be somewhat rigid. This pet carrier is best suited for pet owners who travel frequently by air and need a reliable, airline-compliant solution for their small dogs or cats.
