For pet owners, the thought of traveling with their furry companions can be both exciting and daunting. While road trips may seem like a fun adventure, air travel with pets can be particularly stressful. Many airlines have strict guidelines for pet carriers, and it can be difficult to find one that meets the requirements while also ensuring your pet’s comfort and safety. Soft-sided pet carriers are a popular choice for flying with pets in the cabin, as they are generally more flexible and lightweight than hard-sided carriers. However, not all soft-sided carriers are created equal, and it can be overwhelming to choose the best one for your furry friend.
One of the most important requirements is that your pet carrier must fit under the seat in front of you and the combined weight of your pet and carrier must not exceed a certain limit. In this article, we will take a look at some of the best airline-approved soft-sided pet carriers available in the US, to help make your next trip with your pet a breeze.
