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 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 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.
