British Shorthair Relocation to Singapore | BOAS Test & Short-Nosed Rules

• Pet Samko（British Shorthair）
• Destination Singapore
• Departure 24 June 2026
• Breed type Brachycephalic
• Special handling BOAS test

Samko is a British Shorthair and does not look especially flat-faced. But the airline's breed list classifies him as a short-nosed breed — a classification that decides whether extra paperwork is required, and the step most owners never see coming.

Before departure: not flat-faced, yet still "short-nosed"

Airline restrictions on brachycephalic breeds are based on BOAS risk — Brachycephalic Obstructive Airway Syndrome — rather than appearance alone. Although the British Shorthair's face is not extremely flat, its skull structure and nasal proportions place it on some airlines' restricted lists.

The consequence is an additional veterinary BOAS assessment confirming the cat's airway is fit to fly. Without it an airline may refuse carriage, and that is usually discovered at check-in or at the cargo counter — far too late to fix.

What we did

We checked the airline's latest short-nosed breed list to confirm whether Samko fell inside it, since the list is updated and old information is not safe to rely on. We then arranged the veterinary examination and BOAS assessment and had the documents issued. In parallel we processed Singapore's import permit, microchip, rabies vaccination record and health certificate so that the validity windows lined up, and we liaised with the approved agent in Singapore for clearance on arrival.

Outcome

With the paperwork complete, Samko arrived in Singapore safely.

Three common misconceptions about short-nosed cats

First, "it doesn't look flat-faced, so it isn't short-nosed" — the test is the airline's breed list, not appearance. Second, "the same cat faces the same rules anywhere" — flying to the USA and flying to Singapore can be entirely different, and some routes apply seasonal restrictions to brachycephalic breeds. Third, "any vet letter will do" — the format, issue date and validity of the assessment all matter, and a document issued too early can expire before departure.
