Flying with your cat may sound challenging – cats are known for disliking changes. In reality, flying with a cat is very common and works well with proper preparation. In this guide, we explain what you need to know before boarding a plane with your cat.
Cat travel documents within the EU
When traveling between EU countries, your cat must have an EU pet passport. The passport is issued by a veterinarian and includes:
- Microchip – mandatory identification method for all pets traveling within the EU
- Rabies vaccination – must be valid, and a 21-day waiting period is required after the first vaccination
- Parasite treatments – recorded in the passport by the veterinarian
Your cat must be at least 15 weeks old before traveling. If you are traveling outside the EU or returning from there, you need an EU animal health certificate instead of a pet passport. It must be obtained from an official veterinarian no more than 10 days before travel.
Remember that you are responsible for all documents and vaccinations being up to date. If the paperwork is not in order at the airport, the airline is not liable for compensation.
Transporting a cat in the cabin
Good news for cat owners: most cats are small enough to travel in the cabin. The combined weight of the cat and carrier bag traveling in the cabin may be up to 8 kg, which suffices for the majority of cat breeds.
The carrier bag must be:
- Closed, tight, and well-ventilated
- Spacious enough for the cat to stand, turn, and lie down
- Leak-proof at the bottom
- Can be placed under the seat in front
Airlines set their own size requirements: for example, airBaltic allows a carrier bag up to 55 × 40 × 23 cm and KLM up to 46 × 28 × 24 cm. Always check your airline’s requirements before traveling.
A high-quality carry-on seat is designed precisely for such situations – it meets the most common airline size requirements and offers your cat a safe and calm travel experience.

Airline prices and policies
A separate fee is always charged for transporting a pet. Prices vary by airline:
- Finnair: About 40 € per direction on European flights, 75 € on long-haul flights. Cats allowed in cabin and hold.
- airBaltic: 70 € per cage per direction in the cabin, 110–220 € in the hold depending on size.
- KLM: 70–500 € depending on the flight length and travel method.
- Ryanair: Does not allow pets on its flights.
Remember: Pet seats are limited on every flight. Reserve your cat’s seat immediately after purchasing the ticket – especially during holiday seasons, seats fill up quickly.
Minimizing cat’s stress during the flight
Cats are sensitive to environmental changes, so minimizing flight stress is especially important. Here are some tips:
- Acclimate the cat to the carrier bag at least 2–3 weeks before the trip. Let the cat explore the bag freely and reward with treats.
- Familiar scent calms: Place your cat’s own blanket or clothing with home scents inside the carrier bag.
- Pheromone spray inside the carrier bag can help calm the cat.
- Feeding: Do not feed the cat 4–6 hours before the flight to avoid travel sickness. Offer water as usual.
- Aisle seat: If possible, choose a seat further from the engines – less noise helps the cat to calm down.
- Do not open the carrier bag during the flight – the cat may get scared and escape in the cabin.
Special situations and restrictions
Not all countries allow pet import as easily. Points to note:
- United Kingdom: The EU pet passport is no longer valid – an animal health certificate is required
- Stopover over 24 hours: Some airlines charge a separate pet fee for each flight
- Certain aircraft types: Pets cannot be transported in the cargo hold on KLM’s Boeing 787 or Airbus A321neo aircraft
- Hong Kong, UAE, Australia: Transporting pets with passengers is not possible
We recommend always checking both the airline’s and the destination country’s requirements well in advance of the trip.
From the airport home – the journey continues
The journey does not end at the airport. Continuing by car from the airport also requires a safe transport solution. Crash-tested transport box protects your cat throughout the entire travel chain – from the flight to the car and all the way to the destination.
