What documents, vaccinations and airline rules are required to fly internationally to Nha Trang, Vietnam with a cat?

Step-by-step prep process for flying with a cat: first microchip the cat, next day give a rabies vaccine (e.g., Rabifel combined with Multifel), then wait 30 days. 1–3 days before the flight, visit a state veterinary clinic with the cat's vet passport to get a deworming treatment (e.g., Inspector) and a sticker added to the passport — they issue certificate No. 1 there. At the airport, arrive early to go through veterinary control, where certificate No. 1 is exchanged for certificate No. 5. Also register the pet quota with the airline (Aeroflot in this case) well in advance, and note that in-cabin pet seating is usually only available near the window.

Pet travel must be arranged with the airline ahead of time: one traveler was seeking a passenger able to register a cat on their ticket for an August 29 flight. Do not assume you can add a cat only at airport check-in.

Before booking, check whether your chosen airline accepts cats in the cabin or as checked baggage and what documents it requires. Travelers specifically seek airlines that have successfully carried pets to Vietnam.

A rabies vaccination is a key preparation item. If only a Russian-made vaccine is available, ask the airline and veterinary authorities in advance to confirm that the vaccine and its veterinary-passport record will be accepted for entry to Vietnam via Cam Ranh (CXR).
