1 of the 9 airlines we track will take it under the seat on their published figures: Frontier.Footprint as published, height with at most one inch of squash. Check yours against the source.

12.5 × 10.5 × 16.5 inches. Up to 25 lb. This is a backpack, and we are going to be exact about what that means before anything else.

Standing up it is 16.5 inches tall against under-seat heights of 8.5 to 11, so standing up it goes under nothing. Lying on its back — the only way a backpack ever goes under a seat — the numbers become 16.5 × 12.5 on the floor and 10.5 tall. On those figures it gets under the seat on exactly one of the nine airlines in our guide: Frontier, which publishes 18 × 14 × 11. No squashing and no argument on that one. On the other eight it does not fit under a seat, so it is not a way to fly with your pet on those airlines.

One airline is one airline. If you are flying anyone else, buy an under-seat carrier instead — they are all here, each with its three measurements published.

What it is actually for

  • Both hands free. Padded shoulder straps, worn like a rucksack. Through security, through the terminal, round a car park, up a trail.
  • Large top and side openings for airflow and for checking on your pet without taking the bag off.
  • Up to 25 lb — the highest weight limit of anything we sell.
  • Soft-sided and collapsible, so it folds flat when it is not in use.
  • Two colors, grey and navy blue — pick above. Same bag, same measurements, same price.

Sizing: measure your pet lying down, nose to the base of the tail, and add 2 inches. Then measure standing, floor to the top of the head. Your pet has to be able to stand up and turn around inside.

No carrier is “airline approved”. Airlines publish a maximum size; the gate agent decides whether the bag fits. Compare all nine before you book.

How to measure your pet

Two measurements decide everything.

Length. With your pet lying down, measure from the nose to the base of the tail — not the tip. Add 2 inches. That is the interior length you need.

Height. With your pet standing, measure from the floor to the top of the head.

Your pet must be able to stand up and turn around inside the carrier. That is the rule every airline writes, and the one gate agents actually check. If your pet falls between two interior sizes, take the bigger one — but check its exterior against your airline first. A bag your pet fits in but the airline will not take is no use to either of you.

Shipping & delivery

We ship within the United States only, from warehouses in California and Nevada. Orders placed before 1pm ET on a business day are handed to the carrier the same day; after that, the next business day.

Delivery is typically 1–5 business days depending on how far you are from the warehouse. Shipping is free on every order, with no minimum — you never pay for delivery. Alaska, Hawaii and Puerto Rico are included at the same price; allow a few extra days for those three.

You get a tracking number by email as soon as the label is created.

Returns & exchanges

Thirty days from delivery, in the original packaging and unused. Email us and we will send you a return authorisation and the address for that warehouse before you post anything — a parcel sent back without one cannot be credited.

Wrong size is the most common reason people write to us, and it is the easiest to solve: tell us your pet's measurements and your airline and we will tell you which size to swap to.

Why buy it here

The measurements come first

Sized before it is listed

Every carrier lists a length, width and height. Every backpack lists the back length and the weight limit it is built for. The numbers are on the page before you buy, not in the box after it arrives.

Shipped from inside the U.S.

California and Nevada. No customs form, no six-week wait. Most orders leave in a single parcel; where a kit is drawn from two different warehouses we say so on the product page.

Ask before you buy

Send us your pet’s measurements and your airline. We will tell you which size to order, or tell you honestly that we do not have one that fits.
