“Fits in-cabin” means the carrier's dimensions are within that airline's published under-seat allowance (verified 2026-07-02) — not an airline endorsement. Soft-sided carriers compress slightly; the gate agent has final say. Snub-nosed breeds face extra rules on some airlines. Always confirm on the airline's page before you fly.
