Buying Guide for the Best Southwest Approved Pet Carrier

Choosing the right pet carrier for your travels, especially when flying with Southwest Airlines, is crucial for ensuring the comfort and safety of your pet. The carrier must meet specific airline requirements while also catering to your pet's needs. Here are some key specifications to consider when selecting a Southwest-approved pet carrier.
SizeThe size of the pet carrier is one of the most important factors. It must fit under the seat in front of you, as required by Southwest Airlines. Typically, the maximum dimensions allowed are 18.5 inches long, 8.5 inches high, and 13.5 inches wide. Ensure your pet can stand up, turn around, and lie down comfortably within these dimensions. Measure your pet and compare it to the carrier's dimensions to ensure a good fit.
VentilationVentilation is crucial for your pet's comfort and safety during the flight. A well-ventilated carrier will have mesh panels on multiple sides to allow for proper airflow. This helps keep your pet cool and reduces stress. Look for carriers with at least two to three mesh panels. If your pet tends to get anxious, more ventilation can help them feel less confined.
MaterialThe material of the carrier should be durable yet comfortable. Soft-sided carriers are often preferred for air travel because they can fit more easily under the seat and provide a bit of flexibility. However, they should still be sturdy enough to protect your pet. Look for carriers made from high-quality, tear-resistant fabric with a solid base for support. If your pet is prone to chewing or scratching, ensure the material can withstand such behavior.
ComfortYour pet's comfort is paramount during travel. The carrier should have a soft, padded bottom to provide a comfortable resting place. Some carriers come with removable and washable pads, which are convenient for cleaning. Consider your pet's size and weight when choosing the padding thickness. A comfortable carrier can help reduce your pet's anxiety and make the journey more pleasant for both of you.
SecuritySecurity features are essential to prevent your pet from escaping. Look for carriers with secure zippers and locking mechanisms. Some carriers have additional safety straps that can be attached to a seatbelt for added security during the flight. Ensure that the carrier has a sturdy handle and shoulder strap for easy and secure transport. If your pet is particularly active or nervous, these features are even more critical.
Ease of UseThe carrier should be easy for you to handle and for your pet to enter and exit. Look for carriers with multiple entry points, such as top and side openings. This makes it easier to load and unload your pet. Additionally, consider carriers that are lightweight and easy to carry, especially if you have to navigate through busy airports. Features like pockets for storing pet essentials can also be very handy.
