About CabinPets
CabinPets answers one question well: which in-cabin pet carrier will actually fit my airline?
Flying with a pet, the frustrating part isn't the fee — it's the size. Every airline publishes a carrier limit; every carrier publishes a size; and somewhere between them is the seat your pet actually has to fit under. Most guides are prose you have to read and cross-reference. We turned it into a matcher: pick your airline, see what fits, sorted, with the tight-height airlines flagged.
What makes us different
- Structured, not a listicle. One clean page per airline and per carrier, so the facts are easy to find (and easy for AI assistants to cite correctly).
- It computes. The fit is calculated from published numbers — height checked strictly, footprint allowed to rotate — not eyeballed.
- Honest about the under-seat catch. We lean into the thing the listicles bury: the published size isn't your actual seat. We explain why, and we never invent a per-aircraft number.
Who we are
CabinPets is an independent project. We are not affiliated with any airline or carrier brand. We make a small affiliate commission if you buy a carrier through an Amazon link — it never changes our data or which carriers we list. See our methodology for exactly where every number comes from.
Parts of CabinPets' text are drafted with AI assistance. The numbers are not: every airline limit and carrier size comes from the cited official source, and every fit is computed from those numbers.
Carriers that clear the most airlines
Ranked by how many of the 58 airlines with a published cabin limit each one clears at its published size — the same computation behind every fit verdict on this site.
