Sherpa Original Deluxe Travel Pet Carrier Review: The Cabin Bag Frequent Flyers Trust

Sherpa has been making this carrier for decades, and it shows up on “what to buy before you fly with a pet” lists for a reason: the company backs it with a Guaranteed On Board policy, promising a refund if the carrier is turned away for size on a major participating airline. For anyone who has stressed over gate-checking a carrier at the last minute, that kind of assurance is worth a lot, and it’s the single biggest driver of the thousands of repeat purchases and reorders that keep this carrier a perennial best seller.

Beyond the airline guarantee, it’s just a well-thought-out soft carrier. Mesh panels on multiple sides let pets see out and get airflow, the faux-lambskin liner pad gives them something soft to settle onto, and the shape collapses flat for storage between trips. It comes in a handful of sizes, so it works for cats and small dogs rather than being a one-size-fits-all guess.

Owners consistently describe the carrier as comfortable for the pet and easy to carry, thanks to the padded shoulder strap and top handles that make it simple to switch between a shoulder carry and a hand carry through security lines and terminals. The mesh windows genuinely help with ventilation, and many pets seem to settle down faster in it than in a hard-sided box, likely because the sides flex a bit and it feels more like a den than a crate.

Where it gets more polarizing is interior space. The Sherpa sizing charts are based on a pet’s length and weight, and if your dog or cat is right at the upper edge of a size, owners often report the carrier feels snug rather than roomy — there’s not much wasted space inside once the liner pad is in place. The general advice from longtime users is to size up if your pet is a border case rather than sizing down for a supposedly better fit under the seat.

This is a soft-sided bag, not a structured crate, so it doesn’t offer the same back support or protection as a hard carrier — it can sag a little when a heavier pet shifts around inside, and it won’t hold its shape sitting empty on a shelf the way a molded carrier does. It also costs noticeably more than generic mesh carriers with similar specs, which some buyers balk at until they factor in the airline guarantee. And because pets can have accidents or shed heavily on the included liner pad, several owners note they end up washing or replacing it more often than expected to keep odors in check, especially on longer trips.

If you fly with a cat or small dog more than once a year, this carrier’s combination of name recognition, airline-friendly sizing, and a real fit guarantee makes it one of the safer bets in the category — it’s the carrier most gate agents have seen a hundred times and won’t question. Measure your pet carefully against Sherpa’s size chart before you buy, lean toward the larger option if you’re between sizes, and plan on tossing the liner pad in the wash regularly.

If you rarely travel, mostly need something for vet visits, or want a rigid structure that holds its shape on its own, a simpler or harder-sided carrier may serve you just as well for less money. But for the specific job of getting a pet through an airport and under a seat with minimal drama, the Sherpa Original Deluxe remains one of the most dependable picks on Amazon.
